Frequently asked questions

Yes. Snipmill is free to use and needs no account.

No. Open a tool and use it.

No. There is no watermark on your videos.

An MP4 with H.264 video and AAC audio. It plays almost everywhere: phones, computers, chat apps and social sites.

Up to 2 GB on desktop Chrome and Edge, 1 GB on desktop Safari and 500 MB on phones. Everything happens in your browser’s memory, so very large files need a computer.

A small target for a long video leaves few bits per frame. A lower resolution at that bitrate looks sharper than a blocky full-resolution picture, so we step down when needed.

10 MB holds about 80 megabits. Spread over five minutes that is too little for a sharp picture at any frame size. Cut the video to the part that matters and compress it again, or send a bigger size if the place allows it.

Only a few seconds of it. A 4K clip at 10 MB comes out much smaller than 4K, because the planner steps down to a frame size the budget can fill.

The limit counts the whole message, and mail encoding makes files about a third bigger. Compress to 18 or 20 MB and the video goes as a normal attachment.

It works, but at 240p it looks blurry. For ten minutes, use 50 MB or more, or share a cloud link instead of attaching the file.

Hardly. Going from 60 to 50 MB lowers the bitrate by a sixth, and the planner keeps the frame size when it can. The result is re-encoded once, so it isn't identical, but side by side it is very hard to tell apart.

About ten minutes at 480p, or two minutes at full 1080p. Longer videos still compress, at a smaller frame size.

Your video is over the size WhatsApp sends as a video on your connection (64 or 100 MB). Compress it to 60 MB here, or 16 MB to be sure, then send it again.

Yes, WhatsApp re-compresses every video it sends as a video. Starting from a clean 60 MB file gives it less to throw away than a huge original, so the person you send it to sees a sharper picture.

A minute or two looks fine. For longer clips we lower the resolution so the picture stays clean; trim it to the part you want to show first, and it stays sharper.

Yes. Recordings saved as MKV or MP4, from a game recorder or a screen recorder, both work, and you get an MP4 with H.264 video. A long recording at 19 MB loses detail, so cut it to the moment you want to show first.

At 20 MB, a few minutes still look good. For longer videos, trim them first or send a link to a shared folder instead.

Yes. The file is an MP4 with H.264 video and AAC sound, which opens on phones, Windows, Mac and in the mail app's own preview.

In most browsers, no: the part you keep is copied without re-encoding, and only the frames right at the cut points are encoded again. Browsers without a built-in video encoder re-encode the clip at high quality.

Yes. iPhone videos work, and you get an MP4 back.

Length doesn’t matter, file size does: up to 2 GB on desktop Chrome and Edge, 1 GB on desktop Safari and 500 MB on phones.

"Plays everywhere" re-encodes the video to H.264, which phones, computers and TVs play. "Fastest" keeps the original video when the MP4 format allows it, so it takes seconds and the quality is unchanged, but HEVC video may not play on older Windows PCs.

Up to 2 GB on desktop Chrome and Edge, 1 GB on desktop Safari and 500 MB on phones.

Yes. iPhone MOV files (H.264 or HEVC) convert to MP4. With "Fastest", the video is copied as it is and the conversion takes about a second.

Sometimes it plays, often it doesn't: renaming changes the name, not the format inside. Converting writes a real MP4, and with "Plays everywhere" the video inside is H.264 too.

WebM usually holds VP8 or VP9 video, which MP4 players rarely support. We re-encode it to H.264 so it plays everywhere.

VP9 packs a picture into fewer bytes than H.264, so the same quality needs a higher bitrate in an MP4. If size matters, run the MP4 through Compress Video afterwards.

If the MKV holds H.264 or HEVC video with AAC sound, "Fastest" copies it into the MP4 untouched. Other codecs are re-encoded to H.264 at a similar bitrate.

Files up to 2 GB on desktop Chrome and Edge work here. For longer sessions, OBS Studio can turn its own MKV recordings into MP4 when you stop recording: Settings → Advanced → Recording → "Automatically remux to mp4".

Browsers have no built-in support for AVI, so we use a slower converter that works everywhere. A few minutes for a long video is normal; keep the tab open.

Yes. Convert it to MP4 first, then turn it the right way with Rotate Video. Turning an MP4 is instant and doesn't touch its quality.

The MP4 plays once, like other videos; most apps and sites can loop it, and Instagram and TikTok loop short videos on their own. Colors usually look better than in the GIF, which only has 256.

Yes, with Video to GIF: pick up to 30 seconds of the video, the width and how smooth it plays.

Yes, in Safari and Chrome. Files up to 500 MB work on phones; on a computer you can use files up to 1 or 2 GB.

No. It converts files that are already on your device, like videos you recorded or were sent.

MP3 is a compressed format, so it is re-encoded. At 192 kbps or 320 kbps the difference is very hard to hear.

Convert the whole MP4 here, then open the MP3 in Audio Cutter to keep the part you want, with a fade at the start and end.

Yes. Choose the MOV from your Photos or Files app and you get an MP3 back.

Safari asks whether to download it; it then lands in Files → Downloads. From there you can share it or open it in another app.

Yes. Voice memos are M4A files. Share or save one to Files, then choose it here. 128 kbps is plenty for speech.

It depends only on the quality you pick and the length: about 1 MB per minute at 128 kbps and 2.4 MB per minute at 320 kbps. A 10-minute voice memo at 128 kbps is about 10 MB.

MP3, M4A, WAV, OGG, FLAC and other recordings, and videos (MP4, MOV, WebM, MKV). For a video, only the sound is used.

Yes. Snipmill is free to use and needs no account. Each recording can be up to 60 minutes long. There is no daily limit.

No. Everything runs in your browser, so your files stay on your device. They aren't uploaded.

It uses OpenAI's Whisper speech model, which knows about 100 languages. Pick yours from the list, or let it detect the language. English is the most accurate.

Up to 60 minutes per file on the free plan. There is no daily limit. For a longer recording, cut it into parts with Audio Cutter.

Yes, in Safari and Chrome. Newer phones use their graphics chip and are much faster; on older ones it still works, just slower. Keep the page open while it runs.

Yes. Save the result as SRT or VTT. YouTube, VLC and most video editors can load these files next to the video.

It is made for speech. Sung lyrics over music are often misheard, so expect more mistakes there.

Yes. Pick Translate to English: speech in another language comes out as English text, with the same times.

In the Voice Memos app, tap the memo, tap "…", choose Share, then "Save to Files". Then choose it here from Files.

Only the first time, to download the speech model (145 MB, Wi-Fi is better). After that it is kept on the phone, and memos turn into text without sending anything anywhere.

Up to 60 minutes per file on the free plan. For a 90-minute class, cut it into two parts with Audio Cutter and turn each into text; the times start again at 0 in the second part. On a phone, close other apps first.

Yes, with Voice Recorder: it records in the browser, and the finished recording goes straight on to Audio to Text. Ask the lecturer first; many classes have rules about recording.

No. It writes what is said and starts a new line where the speaker pauses, but it does not tell voices apart. Add names while you edit the lines; a quick read with the recording playing is usually enough.

The recording and the text stay in your browser on your device. They aren't uploaded. Keep the saved files somewhere as safe as the recording itself.

Recordings saved by Zoom (MP4 or M4A), Microsoft Teams and Google Meet (MP4), and any phone recording. For a video only the sound is used.

Each file can be up to 60 minutes on the free plan. Cut the recording into two parts with Audio Cutter and turn each one into text.

Yes. The text is yours. Read it through first: names of guests and products are the most common mistakes. A transcript on the episode page also helps people find it in search.

Yes. Normalize Audio sets an episode to −16 LUFS, a common podcast level, so it sounds as loud as the shows around it.

Yes. Snipmill is free to use and needs no account. Videos can be up to 10 minutes long: plenty for Reels, TikTok and Shorts.

The speech model knows about 100 languages; English is the most accurate. You can also turn speech in another language into English captions. On some browsers, captions in scripts other than Latin can only be saved as SRT or VTT.

Yes. After choosing the video, press "or use my SRT/VTT file" and pick your subtitle file. Its lines appear next to the video, ready to style; the speech model is not needed.

Turning speech into text is usually faster than the video plays, on a computer with a graphics chip. Making the video takes about as long as other video tools here: a few seconds per minute of video on a recent computer, longer on a phone.

Many people watch short videos with the sound off. Captions in the picture show on every app, and you don't have to type them again in each one.

No. A video that is already 9:16 keeps its frame; only a wide or square video is cut to 9:16 from the middle. Choose "Keep frame" if you want a wide video to stay wide.

Yes. Save them as SRT, then in YouTube Studio add subtitles to your video and upload the file.

Not yet: the crop keeps the middle of the picture. If your subject is at the side, choose "Show everything" so nothing is cut off.

No. Everything runs in your browser, so your videos stay on your device. They aren't uploaded.

A wide 16:9 video doesn't fill a phone held upright, so the app adds bars. Cropping it to 9:16 here first makes it fill the screen.

Yes. Instagram Reels and YouTube Shorts use the same 9:16 shape, so one 1080 × 1920 MP4 fits all three.

4:5 for a post in the feed, 9:16 for a Reel or a story. The feed shows posts up to 4:5, so a taller video gets cut in the feed preview.

The app trims anything taller than 4:5 or wider than 1.91:1 to fit the feed. Resizing to 4:5 here first means you choose what stays, instead of the app.

Yes. Square videos show without bars in feeds on Instagram, Facebook and X, and on phones held either way.

Not yet: "Show everything" uses black bars. They look neat on dark themes, and the picture inside keeps its full size.

Phones save which way is up as a note in the file. Current players on phones, Windows, macOS and in browsers follow it; a few old players don't. If a video plays sideways everywhere, the note is wrong: rotate it here to fix it.

Choose 180° and "Mirror left-right": together they flip the picture top to bottom.

Yes, with Video to MP3: it saves only the sound as an MP3.

Not with this tool: it removes all sound. To keep the words, save the sound with Video to MP3 and clean it up in a sound editor.

Yes, up to 4× here. For a stronger time-lapse, run the result through again: 4× twice is 16×.

The whole video changes speed. To speed up one part, cut it out with Trim Video first, speed it up, then put the pieces back together with Merge Videos.

A normal phone video has 30 frames per second; at 0.25× you see about 7 per second. Film in your phone's slow-motion mode (120 or 240 fps) for smooth results.

Copied straight off the phone, a Slo-mo clip is stored at its full frame rate, and Apple's Photos app does the slowing down when it plays it. Slow the file down here, 0.25× for a 120 fps clip, and it plays slowly in every player.

Video formats store only what changes between frames and use millions of colors efficiently; GIF is from 1987 and stores each frame with 256 colors. Where an app accepts MP4, a short MP4 looks better and is smaller.

Yes, with GIF to MP4: the MP4 is usually a fraction of the size and plays everywhere.

Yes. Save the frame as PNG, then add text in an image editor. YouTube recommends 1280 × 720 thumbnails, so a frame from a 720p or bigger video is large enough.

No. The video and sound are copied exactly as they are; only the information around them is left out.

Sometimes. On an iPhone the share sheet has "Options" at the top with a Location switch, and many messaging apps remove it. Files sent as documents, by email, through cloud folders or AirDrop often keep it. Removing it here makes sure.

All the descriptive metadata: location, camera make and model, creation date, encoder, title, comment, chapters. What a player needs to play the file (size, frame rate, codec) stays, because the file would not play without it.

Yes. Choose the video: you get the part you pick as a sound file. To keep the picture, use Trim Video instead.

It is encoded again at 192 kbps, which sounds the same as the original to almost everyone. Keep the original if you plan to cut it many times.

Yes. Choose the video and pick the format; you get only its sound. For MP3 there is also Video to MP3.

About ten times smaller at 128–192 kbps: a 50 MB WAV becomes about 5 MB.

Yes, if you might edit or master the sound again: every MP3 made from an MP3 loses a little more. Share the MP3 and keep the WAV as your original.

No. The WAV holds exactly what the MP3 had, uncompressed, so editors can work with it. What the MP3 left out doesn't come back.

Yes. Audio CDs use 16-bit, 44.1 kHz stereo, which is what an MP3 at 44.1 kHz turns into here, so burning software takes the file without converting it again.

320 kbps keeps the most of a lossless FLAC. 192 kbps is about a third smaller and still sounds the same to most people.

Yes. Choose up to 10 tracks together; they all get the same quality, and "Download all (ZIP)" saves them in one go.

Yes. Choose the video: the picture is copied as it is and only the sound gets louder. You get an MP4.

Phone microphones are set low so loud places don't distort, and speech filmed from a distance ends up quiet. +10 dB or evening out the loudness usually fixes it.

LUFS measures how loud something sounds over its whole length. −16 LUFS is a common target for podcasts and spoken word; music services play songs at about −14.

Yes. Running each episode or clip through the same −16 LUFS target makes them sound equally loud one after another, so listeners don't reach for the volume between them.

Yes. Choose the video: the picture is copied as it is and only the sound is cleaned. You get an MP4.

Many of them send your file to their servers and rebuild the voice with a large AI model. Here the cleanup runs on your device with classic noise reduction: more natural on light noise, less dramatic on very bad recordings, and your file isn't uploaded.

Yes. Snipmill is free to use and needs no account. Recordings and videos can be up to 30 minutes long, and up to 10 files at once.

The low rumble of wind, yes, with Clearer voice on. Strong gusts that hit the microphone change too fast to be removed cleanly.

Start with Light noise removal, Clearer voice and Even loudness, and listen to 10 seconds. Only try Strong if the noise is still loud: it removes more but can make voices thin.

Songs bought on iTunes since 2009 have no copy protection, so they work. Music saved from Apple Music or Spotify for offline listening is locked to those apps and can't be used.

Ringtones copied from a computer can be up to 40 seconds; longer M4R files may not show up in the list. GarageBand on the iPhone keeps at most 30 seconds, and offers to shorten a longer one.

Yes. Once it is on the iPhone, it is in the list for text tones too, and in Contacts → Edit → Ringtone you can give one person their own sound. For a text tone, a few seconds is enough.

Up to 10 at once on the free plan, as long as together they fit in your device's memory: about 2 GB on a computer, 500 MB on a phone.

The clips are encoded again at about the same quality. For a lossless join the clips would need the exact same format and size, which phone clips rarely have.

Yes. An MP3, a WAV and a voice memo can go in one list; they are brought to the same sound settings and saved in the format you pick.

Yes. Snipmill is free to use and needs no account. You can join up to 10 files at once.

The joined file is encoded again at 192 kbps, which sounds the same as the originals to almost everyone.

Yes. Drag the handle on the video's filmstrip, or type the time in "Music starts at". Before that moment the video keeps only its own sound. You can also stop the music before the end.

Yes. Drag the handle on the song's waveform to where it should begin, and the other one to where it should end. With "Repeat" on, that part plays again until the music stops.

No. The picture is copied as it is (H.264 and HEVC videos); only the sound is made new. Other kinds of video are encoded to H.264.

Yes. Record it with any voice recorder, choose it as the second file and set "Video's own sound" to 0% and "Music" to 100%. This page starts that way.

As long as you like: the recording is kept in your browser's memory, about 1 MB per minute. Keep the page open and the phone awake while recording.

No. It is recorded in your browser, so it stays on your device. It isn't uploaded.

No. The video is kept in your browser's memory while you record, from a few MB to about 20 MB per minute, depending on what is on screen, so very long recordings need a computer with enough memory.
