Video Re-encode Studio

A video re-encoder rebuilds your file with a new codec, container, resolution or bitrate — to shrink it, make it play everywhere, or hit an upload limit. This studio reads your video's format locally (codec, resolution and duration), shows every re-encode it can produce, and gives you HandBrake-style control: pick H.264, H.265/HEVC, VP8 or VP9, dial in CRF quality, scale the resolution, cap the frame rate, set the audio bitrate or aim for a target size in megabytes. Nothing is uploaded — the conversion runs on WebAssembly and your device's hardware encoders.

1. Drop your video

   We detect the container, video codec, audio codec, resolution and duration instantly — no upload.

2. Pick a re-encode and tune

   Choose a target (MP4, WebM, MKV, GIF, MP3…) and adjust codec, CRF, resolution, frame rate and audio bitrate — or start from a preset.

3. Convert and download

   Encode locally and download the result. Re-encoding is lossy, so tweak the settings and run it again to compare.

• Auto format detection

  Drop any video and instantly see its codec, resolution and duration — plus every re-encode you can run.

• Full encoder control

  Codec (H.264, H.265, VP8, VP9), CRF quality, resolution, frame rate, audio bitrate and target size — not just a fixed preset.

• 100% private

  Your video is processed in your browser with WebAssembly and WebCodecs. Nothing is uploaded to a server.

• No signup or limits

  No account, no watermark, no daily cap. Re-encode as many videos as you need.

• MOV to MP4

  Convert iPhone/QuickTime MOV videos to universal MP4.

• MP4 to WebM

  Re-encode MP4 to smaller, web-friendly WebM (VP8/VP9).

• MP4 to GIF

  Turn a short video clip into a looping animated GIF.
