CEAC upload errors, including Invalid Image Detected

CEAC can fail even when the file looks correct on your device. Errors such as Invalid Image Detected often mean the portal wants a simpler, cleaner upload copy rather than the original export you started from.

When CEAC fails even though the file looks fine

• The file opens locally, but CEAC still rejects its structure, restrictions, or packaging.
• The upload slot is stricter than the original document source.
• The problem can be a portal constraint, not necessarily a broken PDF.

Invalid Image Detected: what to try

• Save the document as PDF again.
• Print to PDF or save a fresh flat PDF copy.
• Import that cleaner copy into PDF Ready and regenerate a simpler upload-ready version.
• If the document is protected and can be unlocked, unlock it first before generating the new copy.

What PDF Ready can do

• Regenerate a cleaner copy on-device.
• Re-export a simpler version that is more suitable for strict CEAC-style upload constraints.
• Help remove restrictions when the file can actually be unlocked.

What PDF Ready cannot promise

• It cannot fix CEAC outages or portal-side bugs.
• It cannot guarantee that CEAC will accept the file.
• It cannot process a file that asks for a password you do not know.
