8 Best Ways to Fix Gmail Won't Attach Files Error

Fixing Gmail File Won't Attach Error

The fastest way to resolve this issue is to use a different email account from another service provider. Another way can be to upload the file to different cloud storage spaces like Dropbox or even Drive and then share a public link. In the meantime, let’s find out why this is happening and how to fix it.

1. Limits of Gmail attachments

Gmail may be the king of email service providers, but it’s not without its flaws, or should I say limitations. Here they are in no particular order:

  • Total attachment size is limited to 25MB (includes all attachments)
  • Executable files ending in .EXE are not allowed for security reasons
  • The list of supported browsers only includes Chrome, Edge, Firefox and Safari

Gmail will automatically upload the file to Google Drive and add a link to it instead of the attachment size exceeding what is prescribed. You can check the composed mail for Google Drive links.

3. Switch to private browsing mode

Be honest and tell me how many add-ons or extensions you have on your browser? Too much? Any of the extensions could interfere or interrupt the functionality of Gmail. Open the incognito or incognito window and sign in to your Gmail account again.

Check if you can now attach files to Gmail emails. If you can, the problem lies with one of the add-ons / extensions, and you will need to fix it. Otherwise, keep reading because we’re not done yet.

One way to reduce conflicting extensions is to disable half of them to check if the problem persists. Continue with the other half and then turn off the half (8> 4> 2> 1). Continue the halving process until you have one left.

4. Try the Gmail mobile app

What about the browser itself? Are you using an older version or maybe a beta version? Open Gmail on your smartphone and see if you can compose, attach files, and then send the email. There are many ways to transfer files between desktop and mobile.

5. Browser data and cache

Clearing browser cache and data can help solve many browser related issues including the one you are facing where Gmail will not attach files to your email. There is a nifty little shortcut to clear the browser cache if you’re using a Chrome or Chromium browser. All browsers also have this feature in the settings.

Can’t attach files to Gmail on Android? Clearing app cache and data can help on smartphones. Don’t worry, it won’t delete your emails or any other data. All this data is stored remotely on Google’s servers. You’ll need to log back into Gmail and allow it to sync, which shouldn’t take long.

6. Different browser / Update

Can you attach files to a Gmail email on another browser? Some users found that the issue persisted in incognito mode but worked fine on a different browser. I suggest you use an app like Revo Uninstaller to completely uninstall the browser and reinstall it from scratch to get rid of corrupt files and install the latest version.

7. Storage permissions

Gmail needs storage permissions to access and attach files from your mobile device.

Step 1: Open Settings> Applications> Gmail> Permissions> Storage. Make sure it’s set to Allow so that Gmail can access and attach files on your phone.
