What's the best way to compress AVI for WhatsApp?

Upload your .avi file, pick WhatsApp as the platform (it's already selected on this page), and compress. We'll target 15.2 MB to stay safely under WhatsApp's 16 MB cap. Output is MP4 H.264 that plays inline on WhatsApp.

Does WhatsApp accept AVI files directly?

WhatsApp supports MP4, 3GP, and MOV. AVI needs to be converted to MP4 to send as a video message on WhatsApp — otherwise it sends as a generic file attachment.

Will quality drop when compressing to fit?

For short clips under a few minutes, the difference is hard to notice on a phone screen. For longer videos, we scale down resolution (1080p → 720p) before degrading quality at the original size. You can also trim the video to the highlight reel before compressing — that preserves full visual quality in the kept portion.

Do I need an account?

No. Upload, compress, download. Files auto-delete from our servers after 1 hour. No signup, no watermark, no email required.

Compress AVI for WhatsApp

WhatsApp flatly refuses to send AVI as a video message — even on Android where the file system accepts AVI, the send dialog offers it only as a generic document attachment (which loses the auto-play inline preview). This page does the required conversion to MP4 H.264 and compresses to WhatsApp's 16 MB cap in a single pass. Most AVI files we see are either old camcorder rips (typically 480p, already small) or screen recordings from Windows tools like Bandicam/Camtasia (usually 720p/1080p and quite large). Both compress cleanly because AVI's legacy codecs are so inefficient that switching to H.264 alone halves file size before we target a bitrate.

How to compress AVI for WhatsApp

1Drag your .avi file onto the upload zone above (or browse to it).
2WhatsApp is already selected — we'll target 15.2 MB to stay safely under the 16 MB cap.
3Optionally trim to a highlight clip or switch to H.265 for 30-50% smaller files at the same quality.
4Download the compressed MP4 and share it on WhatsApp. Source file auto-deletes from our servers after 1 hour.

What to know about AVI → WhatsApp

WhatsApp sends AVI only as a document attachment (no inline preview) — MP4 is the fix.
Old camcorder AVI at 480p stays 480p in our output; it'll look fine at 16 MB.
Screen-recording AVI from Bandicam/Camtasia benefits most — H.264 alone shrinks these 5-10×.
DivX/XviD codecs inside AVI get replaced with H.264 during compression.

The compression math

A 2-minute 720p AVI screen recording = ~280 MB. WhatsApp target 15.2 MB − 128 kbps audio = ~890 kbps video. H.264 at 720p CRF 30 = ~14.5 MB. 95% reduction, fine for phone viewing.

About AVI files

AVI (Audio Video Interleave) is a legacy Microsoft video format from the 1990s, still commonly produced by screen recording software, older camcorders, and some Windows applications. AVI files are typically 3 to 5 times larger than modern MP4 files at the same quality because they use older, less efficient compression (or no compression at all). CompressYourVideo.com converts your AVI to a compressed MP4 with H.264 encoding, dramatically reducing file size while maintaining visual quality. A 500MB AVI screen recording might compress to 50MB as an MP4. The compressed output is compatible with every modern platform, unlike AVI which most social media sites and mobile devices refuse to play.
