Convert video to MP4, WebM, MOV or MKV

A file that will not play, will not upload or will not open in your editor usually just needs another container or codec. Convert it here — nothing to install.

How it works

1Drop the video — MP4, MOV, MKV, WebM, AVI or M4V.
2Choose the target format, and the codecs if you care which.
3Download the converted file.

What you get

Codecs you choose

H.264, H.265 or VP9 for video; AAC, MP3 or Opus for audio.

Lossless when possible

When the streams already fit the target, “copy” changes only the container: fast, and nothing is re-encoded.

Same result in your code

What you run here is one multipart request over the API, with a webhook when the job is done.

Pay for processing time

One tariff for every operation, capped per file. A failed job is refunded automatically.

Same thing over the API

One header, one multipart request with the file, then poll the job or take a webhook. The same operation you just tried in the browser.

Questions

Which format should I pick?

MP4 with H.264 for anything that has to play everywhere; WebM for websites; MOV for Apple editing tools; MKV to keep several audio or subtitle tracks.

Will converting lose quality?

Re-encoding changes the data a little; the defaults keep it visually close. Choosing “copy” where possible avoids re-encoding entirely.

Do I need an account?

Small files can be converted without signing up. An account adds a daily free allowance and an API key.

Can I automate it?

Yes. Send the file to the API with service “clipconvert” and operation “convert” with the format you want, then poll the job or take a webhook.
