The ones that finish in a second
These conversions don't rebuild the video, they move it into a different container. Nothing is re-encoded, so nothing is lost and it's over before you look up.
Edit a video
There are 14 video tools as well as the conversions, for trimming, cropping, resizing, captioning and shrinking a clip. Trimming and removing the sound copy the picture rather than rebuilding it, so those two finish in about a second. The rest re-encode every frame, which takes as long as it takes.
Every conversion
Working with pictures instead?
The image converter handles PNG, JPG, WebP, AVIF, HEIC and more, and the image tools crop, resize, compress and redact. Everything on this site runs the same way, on your own device.
Common questions
Is the video converter free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The video converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Can you really convert video in a browser?
Yes. ffmpeg, the program behind most video conversion anywhere, has been compiled to WebAssembly and runs inside the page. It's the same tool doing the same work, just on your machine instead of someone else large server. That's why nothing has to be uploaded and why there's no size limit or queue.
Why are some conversions instant and others slow?
A video file is a container with codecs inside it. Moving H.264 video from a MOV into an MP4 changes only the container, so it takes about a second no matter how long the video is. Converting to WebM means every frame has to be decoded and encoded again, which takes roughly as long as the video lasts. Each page says which kind it is.
How big a video can I convert?
There's no limit imposed here, but there's a practical one. The file is held in your browser memory while it works, so a few hundred megabytes is comfortable on a computer and a phone will give up sooner. This is the opposite trade from an upload site, which caps you at a size but does the work on hardware you don't have to own.
