Video Tools (All-in-One)

Trim, crop, video to audio, add music, effects, resize and high-resolution export, convert, compress and video to GIF. All processing is client-side in your browser with ffmpeg.wasm, so your video file never leaves your device and the server pays nothing. No new paid service or key is used.

High-resolution export resizes / upscales the source with ffmpeg. Upscaling cannot add detail the source does not have. First load downloads the ffmpeg engine (about 30 MB) and may take a while; large files can fail on phones with little memory, so use a desktop browser and short clips for best results.
