FAQ
I have an iPhone MOV that won't play on Windows. How do I convert?
Pick MP4 with the High preset. MOV and MP4 share the H.264 codec under the hood, so the conversion is fast and visually lossless. The output plays on Windows, web, Premiere — anywhere.
MP4 vs WebM — which should I pick?
MP4 if you'll send it to someone or upload to social. WebM if it lives on your own website — about 25% smaller at the same quality, but Safari support is more uneven than MP4.
Will I lose quality converting?
The Original preset (CRF 18) is visually lossless — you can't tell the difference. High (CRF 23) is the everyday choice, loses a hair of detail but the file is much smaller. Medium (CRF 28) is for when storage matters more than fidelity.
Does AVI still make sense?
Only for ancient Windows machines or hardware that can't decode H.264. Otherwise pick MP4 — smaller, plays everywhere, supports modern features.
What's the size limit?
5 GB through the browser. No limit through the API.
Can I do this from code?
Yes — all tools here are wrappers over /v1/tasks. Toggle the API view above to see the exact request your form generates, or read the docs for curl / Node / Python examples.

All twelve tools wrap the same /v1/tasks endpoint — three lines of curl will do the same job inside your build pipeline or backend.
