Question details
The user is unable to attach a PDF document stored in Adobe Cloud to an email because the device reports the file size exceeds the allowed limit.

- Product
- Email App / Adobe Cloud
- Device & OS
- Nexus 7 (Android)
- Scenario
- Attempting to attach a PDF file from cloud storage to an outgoing email message.
- Observed behavior
- The email application blocks the attachment process and displays an error message stating that the file is too large.
Verify the exact file size limit of your specific email provider (usually 20MB to 25MB) and check the current size of your PDF document in your cloud storage.
Compress the PDF File
Reduce the overall file size of the PDF so it fits safely within standard email provider attachment limits.
Most email clients restrict attachments to 25MB. If your PDF contains high-resolution images or extensive graphics, compressing the file will reduce its size without significantly impacting document readability.
Use a dedicated PDF app with compression capabilities or an online PDF compressor accessible via your Nexus 7 web browser.
Select the oversized Adobe Cloud PDF file and choose the standard or high compression level to reduce its size.
Save the newly compressed PDF to your device's local storage, then open your email app and attach the smaller file.

Share an Adobe Cloud Link Instead
Bypass email attachment size limits completely by sending a direct cloud download link.
Update Your Email and Cloud Apps
Ensure both applications are up to date to rule out software glitches that falsely trigger file size errors.

Frequently Asked Questions
What is the maximum email attachment size limit?
Most major email providers, including Gmail, Outlook, and Yahoo, enforce a strict maximum attachment size limit of 20MB to 25MB per email. Anything exceeding this must be compressed or shared via a cloud link.
Will compressing my PDF document reduce its quality?
Standard PDF compression generally reduces file size by optimizing background images and removing redundant hidden data, which keeps text perfectly legible. However, high compression settings might slightly reduce the clarity of high-resolution images within the document.
Why does my Nexus 7 say the file is too large even if it's under 20MB?
This can happen due to app caching issues, software bugs, or because email encoding adds roughly 33% overhead to the file's size during transmission. A 18MB file might temporarily swell past 24MB when attached. Clearing your app cache or sending a cloud link usually resolves this.
