2. Go to More Tools, then Extensions.
3. Disable all extensions by toggling them off.
4. Reload Gmail and try the attachment again.
5. Re-enable extensions one at a time to identify the one causing the issue.

Fix 4. Update Your Browser

An outdated browser is a common but overlooked cause of the Gmail not downloading attachments problem. Updating Chrome or Edge often fixes it.

For Chrome: Click the three-dot menu, go to Help, then About Google Chrome. Chrome will check for and install updates automatically.

For Microsoft Edge: Click the three-dot menu, go to Settings, then About Microsoft Edge, and install any available updates.

Restart the browser after updating and try the download again.

Fix 5. Try a Different Browser or Incognito Mode

If the attachment still will not download, try opening Gmail in a different browser or an incognito window. This rules out browser-specific settings or profile corruption.

Fix 6. Check Your Google Account Storage

If your Google account storage is full, Gmail may fail to process or download attachments. You get 15 GB of free storage shared across Gmail, Google Drive, and Google Photos.

1. Go to myaccount.google.com and check your storage usage.
2. Delete large emails, clear your Trash and Spam folders, or remove large files from Google Drive.
3. If you need more space, consider upgrading to Google One.

Fix 7. Check If the Sender Used Confidential Mode

Gmail’s Confidential Mode allows senders to restrict recipients from downloading, copying, or forwarding email content. If an attachment appears but has no download button, the sender has enabled this restriction.

In this case, you will need to contact the sender and request that they resend the email without Confidential Mode, or share the file via Google Drive with normal permissions.

Fix 8. Temporarily Disable Your Antivirus or Firewall

Some antivirus programs and firewalls block file downloads from web apps including Gmail. If none of the above fixes work, try temporarily disabling your antivirus software and then attempting the download.

Remember to re-enable your antivirus immediately after testing. If disabling it resolves the issue, check your antivirus settings and add Gmail as a trusted source.
