Why the upload fails
Ssc and exam application portals often reject files that are scanned at high resolution, exported with large embedded images, or just above the allowed size.
Portal-specific rule
The upload screen may enforce a file-size, format, page, or document-type rule.
Private document
Visa, exam, legal, and identity files should not need a risky upload-download detour.
Manual fix, then permanent fix
The manual fix is to reduce image resolution, remove blank pages, split only when the portal allows it, export again, and retry the upload.
Auto Compress keeps the recurring fix inside Chrome. It prepares the smaller file before the destination website receives it, and it does not store your file on Auto Compress servers for compression.
Check the portal prompt
Use the exact current rule shown during the upload, not an old forum screenshot.
Prepare a smaller file
Compress carefully so signatures, stamps, text, and scanned details remain readable.
Upload normally
Return to the original form and select the prepared file in the same workflow.
