Private video conversion

Convert a whole batch in one go.

Choose several source videos, pick one output format, and let the local queue handle them in order. Your files stay in this browser tab and are never uploaded to ReelShift.

Scaling only ever shrinks a video — larger sources are downscaled, smaller ones are left untouched. Ignored for MP3.

Conversion queue

Processed one at a time on your device

Your selected videos will appear here.

Supported conversions:common video sources supported by the embedded FFmpeg engine can be converted to MP4 (H.264 video, AAC audio), WebM, MOV, AVI, MKV, WMV, an animated GIF (downscaled to 480px wide at 10fps for a reasonable file size), or MP3 audio extracted from the video's soundtrack. The first time you convert something, your browser downloads a small (~30MB) conversion engine and caches it. Every conversion after that starts instantly. Very large files or exotic codecs may take longer or fail depending on your device's memory. Files in a batch are converted one at a time, in order, so memory use stays bounded regardless of queue size.
