MP4 (the most widely compatible container, playable on virtually every device and platform) isn't always accepted where you need to upload, edit or share it. AVI is an older Windows container format, still required by some legacy software and editors, which is usually why people convert to it.

Input: MP4, MKV, MOV, AVI, WEBM, FLV, WMV, M4V, MPG, MPEG, 3GP, TS, OGV, DIVX and more. Output: MP4, MKV, WEBM, MOV, AVI, FLV, WMV, M4V, MPG, 3GP, TS, OGV, GIF, Animated WebP.

Yes. Set any custom resolution (width × height), or use a preset like 1920×1080, 1080×1920 (Shorts), 3840×2160 (4K) or Square (1080×1080).

Both options exist. The online converter on this page uploads your video to convert it, because video encoding needs more processing power than a browser tab can provide. The file is deleted the moment you download the result, and nothing is stored. If you would rather nothing ever leaves your computer, download the free offline Windows app . It runs offline, with no internet connection or upload required.

Yes. Add all your videos at once, set the output format, and convert everything in a single click. Pause and resume anytime.

You control quality. Use a high bitrate preset for near-lossless output, or reduce quality for smaller file sizes.
