Gmail video size limit in 2025

Gmail lets you attach up to 25MB before it hands the file to Google Drive. Follow this guide to stay under the cap or send a high-quality Drive link.

Quick answer

Gmail attachment limit: 25MB per message. Anything larger is uploaded to Drive and shared as a link.

Need to hit the limit? Use the Gmail video size limit calculator for bitrate math or open the 25MB email compressor.

Compress a video to stay under Gmail's 25MB limit

  1. Open the FitToMB Gmail preset or load the calculator to check bitrate requirements.
  2. Upload your video (up to 500MB). Pick 25MB or drop to 20MB if you know the recipient's admin enforces a lower cap.
  3. Enable downscale to 720p or 480p for clips longer than a minute. Gmail recipients usually watch in small preview windows.
  4. Download the optimized MP4 and attach it in Gmail. The result stays within the encoded size budget.
  5. If Gmail still creates a Drive link, accept it and verify sharing settings before you press send.

When to let Gmail upload to Google Drive

Drive links are perfect for longer clips or 4K exports you don't want to recompress. Gmail uploads the file silently and offers sharing controls inline.

Sending to a Yahoo inbox? They will still see a Drive link-the Yahoo Mail guide explains how recipients download large files.

Gmail attachment FAQ

Does Gmail compress videos automatically?

No. Gmail either attaches the file as-is (if under 25MB) or uploads it to Drive. Use the compressor to control bitrate and resolution.

Can I send multiple 10MB videos in one Gmail?

Yes, as long as the combined encoded size stays under 25MB. Otherwise Gmail switches the conversation to Drive.

Why can't recipients view my Drive video?

The Drive link might be restricted to your organization. Change sharing to "Anyone with the link" or download, compress, and resend as an attachment.
