Video converter

Convert video to MP4, WebM, MOV, MKV, AVI or GIF.

Runs in your browser. Your file is never uploaded.

Convert video to MP4, WebM, MOV, MKV, AVI or GIF

Video Converter changes a video's format so it plays where you need it. Turn an iPhone MOV or a WebM screen recording into MP4 for Windows, WhatsApp and video sites, convert MKV to MP4 for a TV, or make a short GIF. You can also lower the resolution to 1080p, 720p or 480p to make the file smaller.

When a video is already H.264, switching between MP4, MOV and MKV copies the tracks instead of re-encoding them, which takes seconds and loses no quality. Everything runs in your browser, with no upload and no queue.

Video converter in short

Add one or more videos, then pick the format and, if you want a smaller file, a lower resolution, then select Convert and download. It's free, there's no sign-up, and it runs in your browser, so the file never leaves your device.

How to use Video converter

  1. 1

    Add your videos

    One or more files: MP4, MOV, WebM, MKV, AVI, 3GP, WMV, FLV and phone formats.

  2. 2

    Pick the format

    MP4 (H.264) plays everywhere. WebM suits websites. MOV for Apple editing apps. MKV keeps every track. GIF for short silent loops.

  3. 3

    Choose the resolution

    Keep the original, or cap it at 1080p, 720p or 480p for a smaller file.

  4. 4

    Convert and download

    Download each video, or all of them as a ZIP.

Good to know

  • Changing between MP4, MOV and MKV is near-instant when the video is already H.264, because the tracks are copied rather than re-encoded.
  • GIF has no sound and gets large quickly; keep clips short.
  • The first time you use an audio or video tool, your browser downloads our 31 MB processing engine. It's kept for next time, so later runs start straight away.
  • Processing happens on your device, so speed depends on your computer. A minute of 1080p video takes roughly one to three minutes on a recent laptop; phones are slower.
  • This tool runs in your browser. Very large files depend on your device's memory.

Why use ConvertFile

  • Instant when possible

    H.264 video moving between MP4, MOV and MKV is copied, not re-encoded.

  • Smaller files

    Cap the resolution at 720p or 480p to cut the size for email and messaging.

  • Never uploaded

    Your video is processed by your own browser and handed back as a download. It isn't sent to our servers, so there's nothing for anyone to see, keep or leak.

  • No watermark, no sign-up

    The video you download is yours as it is: no logo stamped on it and no account needed. It's free for files up to 500 MB.

  • Files up to 500 MB free

    Videos up to 500 MB work without an account, and Pro raises that to 2 GB. Big files are read from your disk as they're processed, not loaded into memory first.

  • Works on any computer or phone

    Windows, Mac, Linux, Chromebook, iPhone and Android, in Chrome, Edge, Firefox or Safari. Nothing to install, and the tool keeps working if your connection drops once it has loaded.

Video converter: common questions

How do I convert MOV to MP4?
Add the MOV, pick MP4 and select Convert. iPhone videos are usually H.264, so this is near-instant and keeps full quality.
Can I convert a video without uploading it?
Yes. The conversion runs in your browser using ffmpeg compiled to WebAssembly. The video stays on your device.
What about H.265 (HEVC) videos?
They're opened and converted to H.264 MP4, which plays on more devices. Saving as H.265 isn't offered because browsers can't encode it.
Can I convert to Apple or Android presets?
MP4 (H.264) at up to 1080p plays on every current iPhone and Android phone, so one choice covers both.
Is Video converter free?
Yes. Video converter is free, works without an account and adds no watermark, for files up to 500 MB. Pro raises that to 2 GB.
Are my files uploaded to a server?
No. Video converter runs in your web browser, so the file is read on your own device and never sent to ConvertFile.
Does Video converter work on Mac, Windows, Android and iPhone?
Yes. It runs in any modern web browser, with nothing to install. Very large files work best on a desktop or laptop, because in-browser tools use your device's memory.
