Why exam uploads fail
Exam application portals often reject files because the KB size, dimensions, file type, crop, or scan quality does not match the current portal rule.
Dimension mismatch
A photo may be the right size but still fail because width, height, crop, or aspect ratio is wrong.
Private application file
Exam photos, signatures, ID proof, and certificates should not need a risky upload-download detour.
Manual fix, then permanent fix
The manual fix is to crop correctly, resize to the requested dimensions, compress toward the exact KB target, and check readability before retrying.
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.
Read the portal prompt
Use the current photo, signature, or PDF rule shown during the application.
Prepare the file
Reduce size carefully so the face, signature, text, stamp, or certificate remains readable.
Upload normally
Return to the exam form and select the prepared file in the original workflow.
