Free video converter — MP4, MOV, WebM, MKV, MP3 and GIF
Convert videos between MP4, MOV, WebM and MKV, extract audio as MP3 or WAV, or turn a clip into a GIF — using your device’s hardware encoder, right in the browser. Your video is never uploaded.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Fast, because it uses your hardware
The converter uses WebCodecs, your browser’s built-in access to the GPU’s video encoders. When the streams already fit the new container they’re copied without re-encoding — instant and lossless.
Large files, no upload
Because nothing is uploaded, a 2 GB video converts as quickly as your device allows, with no waiting for transfers and no size-based paywall.

What can you do with a video converter?
Creators convert iPhone MOV clips and screen-recorded WebM files to MP4 before posting to Instagram, TikTok or YouTube; podcasters and students pull MP3 audio from interviews and lectures; developers and support teams turn short screen captures into GIFs for docs and chats; editors rewrap MKV recordings into MP4 so their NLE accepts them; and motion designers convert Animdock WebM exports into whatever format a client or platform needs.
