Gmail says your attachment is too large

· ~4 min read · Steps verified against Google's Gmail limits and the Drive attach guide

What you see: Gmail refuses to send because your attachments are too big. The limit for personal Gmail accounts is 25 MB total — and here's the part most people miss: when you exceed it, Gmail's documented behavior is to automatically convert the attachment into a Google Drive link in the email. If that handoff fails or you want it done properly, use the flow below.

The fast answer

In Compose, click the Drive icon ("Insert files using Drive") at the bottom of the message instead of the paperclip. Pick your file, choose Drive link, and send. A Drive link has no 25 MB limit — the only ceiling is your Google storage (15 GB free).

Why 25 MB exists (and what the real limits are)

The proper flow: Insert files using Drive

  1. In Gmail, click Compose.
  2. At the bottom of the message, click Insert files using Drive (the triangle logo, next to the paperclip).
  3. Select the file(s) you want to attach — you can upload from your computer at this point too.
  4. At the bottom of the dialog, decide how to send: Drive link (works for any file, any size) or Attachment (only available for non-Docs/Sheets/Slides files under the limit).
  5. Click Insert, then send.

The sharing prompt (the step that trips people)

If your recipients don't already have access to the file, Gmail stops you: "you'll be prompted to change the sharing settings of the file before you send your message." Choose:

For sensitive files, prefer "Restricted" sharing set in Drive itself: select the item > Share > under General access choose Restricted, add your recipients explicitly, then paste the link into the email.

When you truly can't use Drive

Some recipients (banks, government forms) demand real attachments. Options: compress with ZIP (helps for uncompressed formats, does nothing for already- compressed video/PDF), split archives into under-25MB parts, or use a file- transfer service and send the download link. If Drive itself rejects the upload, you're likely out of storage — see our Drive storage guide.

You'll know it worked when

The message sends, and the recipient opens the file straight from the link — no bounce-back, no "attachment removed" notice. Send yourself a test copy first if it matters.

Still broken?

If Drive rejects uploads or links error out, check storage at drive.google.com/settings/storage — and the Gmail Help Community for account-specific quirks.

Drive links are only unlimited up to your quota. Google One plans start small and scale — compare tiers if 15 GB is the real bottleneck.
