GOOD TO KNOW

A few small details.

Does my video get uploaded?

No. Compression and previews run locally in your browser. Your video is never sent to a server.

Which formats can I use?

Choose MP4, MOV, WebM, or MKV input. Export MP4 with H.264 or WebM with VP9. AV1 is available when your browser supports encoding it.

How accurate is the size estimate?

The quick estimate uses your video’s bitrate and audio packets. Check samples encodes short sections for a closer prediction. The final size depends on the footage and encoder, so estimates include an expected range.

Which browser should I use?

A browser with WebCodecs is required. The app checks your device’s encoding capabilities; GPU denoising also needs WebGPU. Performance and supported codecs depend on your browser and hardware.
