Compress PDF for UPSC Form Upload
UPSC-style exam forms can require photos, signatures, certificates, ID proof, category documents, and scanned PDFs. Upload errors often happen because a file is just over the portal limit.
Last verified: July 18, 2026. UPSC and exam portal upload rules can vary by exam cycle, document field, photo/signature requirement, and official notice. Follow the live portal prompt.

Why the upload failed
Upload errors usually come from files that are just over the limit, exported in the wrong format, or created from high-resolution scans and phone photos.
Upload target
Exam portals often have separate limits for photos, signatures, and PDFs.
Portal mismatch
The file was exported from a phone scanner without compression.
Manual fix, then permanent fix
Compress each document field separately, keep certificate numbers readable, and follow the exact photo/signature/PDF instructions shown by the exam portal.
Auto Compress helps prepare smaller exam-form files in Chrome before the portal receives them.
Check the prompt
Use the latest file-size and format rule shown by the upload portal.
Prepare a smaller file
Compress carefully so the document remains readable.
Upload normally
The destination website receives the smaller file. Auto Compress does not store it for compression.
