Select a AVI video file
AVI (Audio Video Interleave) is a Microsoft container from 1992 — the format of camcorder archives, DivX/XviD rips and old Windows software. Modern phones, smart TVs, browsers and editing apps often refuse AVI files or play them without sound, because the codecs inside (DivX, XviD, MJPEG, MS-MPEG4) are long deprecated. Converting to MP4 with H.264 video and AAC audio makes the file playable everywhere, streamable on the web, and typically smaller. Because most AVI files use legacy codecs, this tool defaults to Re-encode mode, which rebuilds the video in modern codecs while preserving quality.
Drop your AVI file — old camcorder clips and DivX/XviD videos welcome.
Pick the conversion options that fit — sensible defaults work for most files.
Get your converted file instantly — it plays on every device and platform.
AVI files usually contain legacy codecs like DivX, XviD or MJPEG that modern devices no longer ship decoders for. Converting to MP4 (H.264 + AAC) solves this — every phone, TV, browser and editor made in the last decade plays it natively.
Re-encoding always involves a generation of compression, but at the High quality preset the difference is visually negligible — and the MP4 is usually smaller than the original AVI. If your AVI already contains H.264 video (rare but possible), try Fast Copy mode for a lossless remux.
No. The conversion runs entirely in your browser using FFmpeg compiled to WebAssembly. Your video never leaves your device — it is 100% private and works even on sensitive footage.
The limit is your device’s available memory since everything runs locally. Most modern computers handle AVI files up to 500 MB–1 GB comfortably.
Yes. In Re-encode mode you can downscale to 1080p, 720p or 480p and pick a quality preset — useful for shrinking huge old camcorder files before sharing them.
Completely free, no watermark, no sign-up. Because the conversion uses your device’s own processing power instead of our servers, we can offer it without limits.
