Convert video format — MP4, WEBM, MOV or MKV

Drop in a video and pick what you need back: MP4 for anything, WEBM for the web, MOV for Apple and editing, MKV for keeping everything.

No account, no watermark. Works just as well as a large video converter to MP4 — files up to 1200 MB, not only short clips.

Every converter here is free, full size, no account. Photos convert in your browser and never leave it, except camera RAW files and SVG tracing. Those, like video, audio and e-books, need our server — and we delete them right after.

Which one do you actually need

MP4 is the answer nine times out of ten. Every phone, every browser, every TV, every editing program opens it. Convert into MP4 first if something refused your file and you do not know why.

WEBM is noticeably smaller at the same quality and plays in every current browser, so it is the right pick for a video on your own website. Older desktop players and some phones will not open it.

MOV is what iMovie, Final Cut and QuickTime prefer — pick MOV as the target if you need to convert MP4 to QuickTime specifically. MKV holds anything — multiple audio tracks, subtitles — which makes it good for archiving and bad for uploading anywhere.

Whichever target you pick, this works as a full online video converter. It's a free video converter, and a free online video converter at that. In short, a video converter free of watermarks, accounts and installs. Most video converters, video and converter sites alike, ask you to install something or register first; this one doesn't. A quick online video convert is drop, pick, download, and it's a video converter tool for any device: to convert video online from a phone, the steps are the same. It doubles as a general video file converter too: MP4 to WEBM, WEBM to MP4, MOV to MKV, and back again, without leaving the browser tab.

What conversion costs you

Changing format means re-encoding, and re-encoding always loses a little. Not enough to see on one pass, plenty to see on five. So convert from your original rather than from a file that has already been through two other tools.

Anything taller than 1080 pixels is scaled down to 1080. A 4K file at a sensible bitrate looks worse than 1080p at the same bitrate, so this is the choice that keeps the result looking right rather than the number looking big.

Sound comes along

The audio track is converted with the picture — AAC for MP4, MOV and MKV, Opus for WEBM. A file with no sound stays a file with no sound. If you want the audio on its own, pull it out as an MP3; if you want it gone, mute it.

About your file

This runs on our own machine, not in your browser, like every video tool here. Your file is deleted the moment the result is ready. Limits: 1200 MB and 20 minutes per upload on the free tier.

How to convert video format

To change video format, you don't need to install software either. Wondering how to convert video format without installing anything? Drop your file above, pick MP4, WEBM, MOV or MKV, and download — that's it. On Android and iPhone, how to convert the video format on your phone works the exact same way: open it in the browser and go. And if you specifically searched how to convert video file format for editing software, MOV is usually the safe target. People who search for "convert it video" usually mean: I have this clip and want it in another format. That is the whole job here: drop the file in, pick MP4, WEBM, MOV or MKV, and download.

One tool for every device and format

It reads every common video format: MP4, MOV, WebM, MKV and AVI, plus older MPG, FLV and 3GP files and GIFs, which makes it close to an all video format converter on the input side. Four formats come out: MP4, WEBM, MOV and MKV. As a video type converter it sticks to those four on purpose rather than offering dozens nobody needs.

On a phone it works as an Android video format converter or on an iPhone in Safari, since nothing gets installed. An old clip in 3GP from a phone or camcorder goes in like any other, so the 3GP video format converter case is covered too: pick MP4 and it plays everywhere, iPhones included.

Not what you're looking for?

Searching to convert a video into text or a transcript rather than another video format? That's a different job — ScribeGrab turns video or audio speech into text. Comparing this to Online-Convert or the Kapwing video converter? Same idea; this one needs no account and adds no watermark.

4K, HD and what happens to the resolution

Anything larger than 1080p is scaled down to 1080p on the way through, automatically; nothing smaller is touched. That also makes it a 4K video converter and a basic video resolution converter in one direction, a 4K to 1080p converter that needs no picker: to convert MP4 to 1080p from a 4K phone clip, just convert it. It isn't an HD video converter in the upscaling sense, though: nothing is made bigger. So uploading a 4K file is, in effect, how people convert 4K to 1080p here without a separate step. To pick a specific resolution yourself (720p, 480p), use the video resizer.

Every format change re-encodes, whatever the movie converter or resolution converter, so the video quality drops a touch each time. It's a video quality converter only in that limited sense: invisible on one pass, visible on five. Convert from your original, and pick MP4 unless you have a reason not to.

Common questions

What video format should I use?

MP4 unless you have a reason not to. It plays on everything. WEBM is smaller and right for your own website; MOV suits Apple editing software.

Does converting lose quality?

A little, every time — re-encoding always does. One pass is not visible; convert from your original rather than from an already-converted file.

Why is my 4K video coming back as 1080p?

Anything over 1080 pixels tall is scaled down. At a sensible file size, 1080p looks better than 4K squeezed into the same bitrate.

Can I convert a GIF this way?

Yes: drop the GIF in and pick MP4, WEBM, MOV or MKV. To convert GIF to video it is the same upload box, and a GIF to video convert works the same whichever target you pick (a GIF convert to video takes seconds). See GIF to MP4 for what that saves you.

Is there a file size limit?

1200 MB per upload, and no daily cap. There is no watermark and no account.

Is my video uploaded?

Yes. A browser cannot rewrite a video container, so this runs on our machine and the file is deleted right after.

Can I convert file to video format that plays on a TV?

Yes: pick MP4, which almost every smart TV and media player reads. To convert a file to MP4 from an old camcorder format, the same steps apply; any online converter would need to re-encode it too.

How do I get an MP4 that plays everywhere?

Drop it in and pick MP4: converting a video into MP4 is the safest choice when you don't know what the other side can open, and that is the whole video converter MP4 process. It is not only a converter to MP4, though: pick WEBM for a smaller file in the WebM format for your own website (convert to WebM format if every current browser is your audience), or MOV or MKV. Large files up to 1200 MB work too, with no account, no watermark and no charge.

Which video format works for LinkedIn and other platforms?

MP4 — every platform including LinkedIn accepts it, and it's the safest default here too. If you need to switch the format from mov to mp4 specifically for an upload, pick MP4 as the target and download.

Can it turn a video into audio, or audio into a video?

No to both. Every output is a video container, never a standalone MP3 or other audio file, so this page does not convert video into audio and has no "convert to video to MP3" option; to strip the sound out, remove audio from video hands back a silent video. Nor does it go the other way: to convert audio to video, convert sound to video or convert audio into video, say MP3 to video for a podcast clip, you need at least one image as the picture track, combined with the sound in a video editor. To convert MP3 audio into an existing video, add music to video lays the track under a clip you already have.

Do I need VLC to convert a video format?

No. VLC can convert files if you already have it, but this page needs nothing installed: you use it from the browser and the conversion runs on our server.

Can I change a video format on an iPhone?

Yes — open this page in Safari on your iPhone and convert any supported format on the go.

How do I convert MP4 to MOV online?

Drop the MP4 onto this page, pick MOV as the output format, and download the result. Useful when Apple software like Final Cut or iMovie needs a MOV file.

Which formats can it read and write?

It reads MP4, MOV, WebM, MKV and the older AVI video format, and converts between MP4, MOV, WEBM and MKV; an AVI video in and MP4 out gives the most compatible result. An iPhone's HEVC-encoded MOV is decoded on our server like any other clip, so you don't need to change your camera's format setting first.

Can I convert to HD or change the quality?

Down to 1080p, yes: a 4K upload is capped at 1080p automatically, so to convert 4K video to 1080p you just convert it. To convert to HD video from something smaller, nothing here adds detail; that would need an upscaler. Quality only changes downwards, as a side effect of re-encoding: to change it on purpose, compress video sets a file size and the video resizer sets the resolution.

Can I paste a YouTube or other link?

No. Paste-a-URL isn't offered anywhere on this site; the box needs an actual video file, and that applies to any link: YouTube, Vimeo, a Google Drive or Dropbox share. There is no YouTube convert video option, no YouTube to video download and no link to video fetcher. If the clip is your own and you have the file, drop it in to convert YouTube video exports to MP4, WEBM, MOV or MKV like anything else; to convert YouTube clips you don't own, you'd need the owner's permission anyway.

Which format should I use for X (Twitter)?

MP4, which is what X expects and the safest default for every other platform too. To convert videos for Twitter, pick MP4; X re-compresses whatever you send anyway, so there is no special export mode that would change what comes out the other end.

Can I get a transcript of the video?

No: this only changes the container and never reads what is said. For a video to text convert job use ScribeGrab, the sister site that turns video to transcript: its transcription gives a video transcript, with timestamps next to each line, in a downloadable video transcript format. A plain format converter has no way to convert video to text or produce a transcript with timestamps.

Can I convert to midi format from a video's soundtrack?

No — MIDI stores individual notes and instruments, not a video or an audio waveform, and turning a real recording into playable notation is a specialised pitch-detection job no tool on this site attempts. This converter only swaps one video container for another; the audio track inside is carried over untouched, never analysed.

Can I convert video to photo here, or convert video to stills for a whole set?

Not this page — it changes the container, not what's inside it. Video thumbnail generator grabs a single frame at whatever second you pick and hands it back as a JPG at the video's own resolution; run it once per moment you want if you need more than one.

Can I convert eps format files here?

No — EPS is a vector graphics format, not a video or a container this page has ever touched; nothing on this converter reads or writes it.

Which output should I use for iPhone?

Convert to iPhone-friendly MP4: iPhones play MP4 and MOV. To convert to iPhone video format free, pick MP4 and download.

Is it free, and is it a website or an app?

A website, so nothing is installed, and the online video converter free tier has no daily cap: the only limits are 1200 MB and 20 minutes per file. It is a format changer between four common formats, nothing more, and it deletes the file afterwards.
