Why Convert Videos in the Browser?
Video files come in many formats, and devices and platforms each prefer their own. Converting in the browser means no software to install and no files leaving your device.
Because everything runs locally, there is no upload queue and no server-side file cap. Even large files convert at the speed of your own machine.

Frequently asked questions
Which video formats are supported?
MP4, WebM, MOV, MKV, AVI, FLV, WMV, MPEG, 3GP, TS, M4V and OGV. More formats are added as the tool grows.
Does converting reduce video quality?
Format conversion keeps the original quality unless you choose a re-encoding preset that trades size for quality. The converted file is a new copy; your original stays untouched.
Is my video uploaded anywhere?
No. The file is processed locally in your browser with the codecs your browser provides. Nothing is uploaded, stored, or tracked.
Your videos never leave your browser
All processing happens locally on your device. Nothing is uploaded to a server, stored, or tracked.
