- Product
- Device & OS
- not provided
- Scenario
- Sending a PDF document through an electronic signature service like Adobe Acrobat Sign.
- Observed behavior
- The electronic signature platform blocks the document from being sent, citing a 10 MB file-size limit.
Check the exact file size of your current document and confirm the specific file-size limit of your electronic signature provider (such as the 10 MB limit for Adobe Acrobat Sign).
Compress the PDF Document Below 10 MB
Reducing the file size of your document is the most effective way to meet the 10 MB limit without losing the content necessary for the electronic signature.
Electronic signature platforms enforce file-size limits (often 10 MB) to ensure fast processing and reliable email delivery. If your document exceeds this limit, compressing the file will optimize background images and fonts, allowing it to pass the size check.
Launch your preferred PDF editing application and open the oversized document you intend to send for signing.
Navigate to the 'Tools' or 'File' menu and select the 'Compress PDF' or 'Reduce File Size' option.
Choose a compression level that brings the estimated output size below 10 MB. Standard compression is usually sufficient while maintaining readability.
Click 'Compress' and save the newly optimized file to your computer. Upload this new file to your electronic signature platform.
Split the Document into Multiple Parts
Use this solution if your document is extremely large and cannot be compressed below 10 MB without severe quality loss.

Frequently Asked Questions
What is the standard file-size limit for Adobe Acrobat Sign?
For most individual and standard business plans, the file-size limit for a single document sent for electronic signature via Adobe Acrobat Sign is 10 MB. Enterprise tiers may have different limits depending on their specific service agreements.
How do I check the file size of my PDF before sending?
On Windows, right-click the PDF file and select 'Properties' to view the size. On a Mac, right-click (or Control-click) the file and select 'Get Info'. Ensure the size displayed is less than 10 MB (approximately 10,240 KB).
Will compressing a PDF affect the legality or validity of the signature?
No. Compressing a PDF prior to sending it for an electronic signature only optimizes the background code, images, and fonts. It does not alter the text of the agreement or affect the legal validity of the digital signature applied afterward.
Can I remove unnecessary pages to reduce the file size?
Yes. If your document contains draft pages, redundant cover letters, or heavy image exhibits that do not require signing, you can delete those specific pages using a PDF editor before uploading the file to the signature platform.
