What File Size Is Considered Large in Adobe Send?

Product: Adobe Send
Device & OS: not provided
Scenario: Sharing documents or media that are too large for standard email attachments.

Determine When to Use Adobe Send for Large Files

Identify the 5 MB threshold and use cloud-based sharing to bypass restrictive email delivery limits.

Email providers generally impose strict limits on attachment sizes to prevent server overload. This often causes delivery failures for files that exceed 5 MB to 20 MB. Adobe Send is specifically designed to handle these larger files securely by sending a link rather than the actual file.

Check the document file size

Right-click your file and select 'Properties' on Windows, or 'Get Info' on Mac, to view its exact size in Megabytes (MB).

Identify the 5 MB threshold

If your file is larger than 5 MB, it is considered 'large' in the context of standard email sharing and is a prime candidate for Adobe Send.

Verify your specific Adobe plan limits

Log into your Adobe account to check the maximum file upload size supported by your specific subscription plan, as upload limits can vary based on your tier.

Frequently Asked Questions

Why do email providers block large file attachments?

Email servers typically enforce attachment limits (often around 20-25 MB, but sometimes as low as 5 MB) to prevent server overload and ensure smooth mail flow across networks. Exceeding this limit results in a bounced email.

What is the maximum file size I can send with Adobe Send?

The maximum file size depends entirely on your specific Adobe subscription plan. You must check your Adobe account settings or billing details to see the exact maximum upload limit for your current tier.

Can I share large files without using Adobe Send?

Yes, you can use alternative cloud storage and sharing ecosystems like WPS Cloud, Google Drive, or OneDrive to upload your large documents and share them via a secure URL instead of an email attachment.
