Gmail Video Compressor

Compress videos locally before attaching them in Gmail, with an editable target size and compatible MP4 output.

When to use the Gmail compressor

Prepare product walkthroughs, support evidence, class clips and personal videos for a Gmail message.

Duration and quality

Keep attachment clips short when possible. Longer videos require lower bitrate and often 720p or 480p output.

Recommended resolution

720p by default; 480p when duration is more important

Recommended output settings

Use MP4/H.264, check the final attachment in Gmail and keep a safety margin below the limit shown for your message.

If compression or upload fails

Retry with H.264, lower the resolution or target size, trim unnecessary footage, close other tabs and start again from the original. Recheck the platform's current upload screen before sending.

All videos are processed locally in your browser. Refreshing or closing the page clears the video and result.
