Gmail Attachment Size Limit per Email
The Gmail attachment size limit applies to the email as a whole, not just one file. Several smaller files can still push one message over the limit.
Pick the PDF, image, or video you want to email. The size check is free.

Sending to work or school?
You do not normally need this. If you are sending to a work, school, or company address, paste it here and we will check the mail service when we can.
You can leave this empty. It is only here if you want to check a work, school, or company email address.
Optional Devenia help
Rather have us make the smaller copy?
The check and advice above are free. You can try the changes yourself, or ask Devenia to make a smaller copy for you.
We use this to send the finished file and receipt.
What this page is for
Use this guide when a Gmail message has multiple attachments or one file that is close to the limit. The total size can grow after email encoding, so staying comfortably below the limit is safer.
If the message is too large, reduce one or more files or use a Drive link.
How to handle it
- Add up the size of all attachments before sending.
- Leave room for email encoding overhead.
- Compress the largest PDF, image, or video first.
- Split attachments across messages only when that is acceptable to the recipient.
- Use Drive for files that cannot be reduced safely.
What to check before sending
- Open the smaller file before sending it.
- Check the final file size, not just the compression setting.
- Keep the original file until the recipient confirms the smaller copy works.
- Make sure important text, faces, forms, signatures, or charts are still clear.
