WhatsApp video will not send: make the file smaller

Steps

1. Check the current message or limit in the send screen.
2. Keep the original and convert a copy to MP4 at a practical size.
3. Play the converted file before sending.

ClipForge

Free conversion runs in your browser. When WhatsApp cannot send a video, check the message in the share screen and create a sharing MP4. Verify playback as well as file size.

Checklist before converting

• Keep the original file
• Check the error shown by the destination
• Trim only unneeded footage
• Play the result to the end

What to check first

Keep the original file and make a separate sharing copy. Check the error on the destination service, the video length, and whether the original plays correctly before changing several settings at once.

Recommended starting settings

For sharing, start with MP4 and H.264. Try 720p when size matters or 1080p when detail matters. Play the finished file on the phone before uploading or sending it.

On a phone

After choosing a video on iPhone or Android, wait for its name and size to appear. If it does not appear, reload the browser, select it again, and allow Photos or Files access when asked.

If it does not work

Update the browser, check free device storage and use a stable connection. If sharing still fails, play the converted file to the end, then try a shorter clip or lower resolution.

About sharing limits

Limits and supported formats on LINE, X, Instagram, WhatsApp, and other services can change. Follow the current message in the service instead of relying on an old fixed number.
