What is the Gmail attachment size limit for videos?

A personal Gmail account can send attachments up to 25 MB. Google's support page says that work and school accounts get a limit set by their administrator, so check with your organisation if you use one.

What the limit means for a video

The limit is about the total size of the attachments you send. A single 25 MB video already uses the whole allowance, so a video plus a document or two can go over the limit even when each file looks small.

If your video is bigger than 25 MB

1. Make it smaller. Compress a video to 25 MB in your browser. If you need it smaller still, compress video for email aims for under 18 MB.
2. Send it through Google Drive. Google's support page recommends Google Drive for files over the attachment limit. Choose this when the video has to stay at full size.

What we measured

On an iPhone running iOS 18, a 33-second video of 63.3 MB compressed to 12.19 MB with the 25 MB option, in about 5 seconds. That is one measured run on one device, not a promise. The size you get depends on the video, so the tool measures the real file before you can save it.

Your video stays on your device

Compression runs inside your browser. The video is never uploaded to us or to anyone else.
