Free video converter
that never uploads

Turn MOV, MKV, WMV and AVI into MP4, make a video smaller to send it, cut the start or end, or save it as a GIF — all on your own device.

  • No sign-up
  • No upload

Two converters, one page

Fast convert

MP4, MOV, WEBM and MKV are handled by the video encoder built into your browser. If only the container changes, it takes seconds.

Old formats

WMV, AVI, FLV and MPG are unpacked with FFmpeg and re-encoded to MP4 by your browser. It works, but slowly — the page says how long to expect.

Picked for you

Drop a file in the wrong box and the page tells you which one to use, with a button to switch.

How to convert a video to MP4

  1. Drop your video above.
  2. Choose MP4 (plays almost everywhere) or WEBM.
  3. Optionally lower the resolution, set a target size or trim the start and end.
  4. Click Make MP4 and download the result.

FAQ

Is my video uploaded?

No. Everything happens in your browser. The video never leaves your device, which also means there is no upload wait for large files.

Which browser works best?

Recent Chrome or Edge on a computer. Safari and Firefox work for most tasks, but some encoders may be missing; the page tells you if your browser cannot make a format.

Why is MP4 recommended?

MP4 with H.264 video and AAC sound plays on phones, Windows, Mac, smart TVs and every messenger. WEBM is smaller for the web but not every device opens it.

Is there a file size limit?

No fixed limit for the fast converter. Old formats (WMV, AVI) may stop on files over about 1 GB because the whole job runs in browser memory.
