Repair Your Adobe Acrobat Installation
Repairing the Acrobat software can resolve underlying background glitches that cause incorrect file size readings during the sending process.
A small PDF might trigger false size or sending errors if your Adobe Acrobat installation is corrupted or experiencing a temporary malfunction.
Launch Adobe Acrobat on your computer and navigate to the 'Help' tab located in the top menu bar.
Click on 'Repair Installation' from the dropdown menu. Wait for the built-in diagnostic and repair process to complete.
Once the repair is finished, close Adobe Acrobat completely, restart your computer, and attempt to send the 3 MB PDF document again.

Frequently Asked Questions
What is the maximum file size allowed for Adobe Sign?
The maximum file size for uploading a document to Adobe Sign typically depends on your service tier. Standard accounts generally support files up to 10 MB or 25 MB, though enterprise tiers may allow larger files. You should check your specific plan details in your Adobe account dashboard.
Why does a compressed PDF still fail to send in Adobe Acrobat?
Even if a PDF is small in megabytes, hidden metadata, complex fonts, corrupted objects, or an underlying software glitch in Acrobat can trigger false file-size errors. Repairing the installation or re-saving the PDF usually resolves this.
How can I reduce the size of a PDF further before sending?
You can reduce a PDF's size in Acrobat by going to File > Reduce File Size, or by using the PDF Optimizer tool to compress images and discard unnecessary background objects. Alternatively, free tools like WPS Office offer quick PDF compression features.
Are there free alternative tools to add electronic signatures to PDFs?
Yes, software like WPS Office provides built-in, free tools to draw, type, or insert image-based signatures into your PDF documents quickly and easily without needing a premium subscription.
