How to Fix "Error Processing Image" When Adding a Signature in Adobe DC

Product: Adobe Acrobat DC
Device & OS: not provided
Scenario: Attempting to add a 90 kB JPG image as a personal signature into a PDF document.
Observed behavior: The application fails to process the image and displays the prompt: 'An error was encountered while processing this image.'

Before you start

Ensure your device is connected to a stable internet network, and verify that your JPG file is not corrupted by opening it in a standard photo viewer before attempting to sign the document.

Solution 1Recommended

Refresh Your Account Session and Device

Temporary app glitches or expired login sessions can often interrupt image processing. A quick reset usually resolves this.

Adobe Acrobat DC requires active session authentication for certain cloud-related features to function properly. Refreshing this connection can clear background errors.

Save your current work

Before doing anything, save your current PDF locally to prevent any data loss.

Sign out of Adobe DC

Go to your profile icon or the app settings menu and select 'Sign Out'.

Reboot your device

Completely turn off your smartphone, tablet, or computer, and then turn it back on to clear the system cache.

Sign in and retry

Open the Adobe DC app, sign back in with your credentials, and attempt to upload your JPG signature again.

Check network connection: Make sure your Wi-Fi or cellular data is active when signing back in, as Adobe verifies your subscription status online.

Solution 2

Update the Adobe Acrobat DC Application

Using an outdated version of the app might result in compatibility bugs with image processing algorithms.

Frequently Asked Questions

Is 90 kB too large for an image signature in PDF apps?

No, a 90 kB file is very small and perfectly optimal for PDF signatures. If an app rejects a file of this size, it is typically due to a software glitch, cache issue, or temporary network error rather than a size restriction.

What is the best image format for a digital signature?

PNG is generally considered the best format because it supports transparent backgrounds, allowing your signature to seamlessly blend over text and lines. However, high-contrast JPG images are also widely accepted and functional.

Why does Adobe DC say it cannot process my image?

This error can occur due to corrupted app cache, an outdated app version, an unexpected session timeout, or slight file format corruptions. Restarting your device and updating the software usually fixes the error.
