Compress a WhatsApp-ready MP4 directly in your browser without uploading the source video to our server.
WhatsApp is convenient for quick video sharing, but large videos still create friction. A phone recording, product demo, class clip or travel video may fail to send, upload slowly, or look worse after the app compresses it. The practical answer is to choose the right path before sending: compress the video locally when you want a smaller file, use MP4/H.264 for compatibility, or share a link when the original quality matters more than file size.
Do not aim exactly at the platform limit. If you need the file to stay under a certain size, set the target slightly lower, such as 90MB for a 100MB limit or 1.8GB for a 2GB limit. A margin helps because metadata, container overhead and platform-side processing can slightly change the final file size. For short clips, a smaller target usually keeps acceptable quality; for long videos, leave more space.
720p for everyday sharing; 1080p for short detail-heavy clips
For everyday sharing, MP4 with H.264 video and AAC audio is the safest combination. MOV, AVI, MKV or WebM files can work in some situations, but recipients may use different phones, app versions or operating systems. If your source video comes from editing software, screen recording tools or a camera app, converting to MP4/H.264 before sending avoids many playback problems.
If a video still will not send, check the file size, switch to MP4/H.264, try a stronger compression target, verify your network connection and restart the app if needed. For very long videos, trim unnecessary openings, pauses or endings before compressing. If the result looks too soft, increase the target size and compress again from the original file rather than recompressing the already compressed output.
