Readability matters
Exact compression depends on the original file. Scanned documents usually compress differently from text PDFs. If the result is blurry or still too large, try a higher target, rescan around 150 DPI, or split a multi-page PDF.
Before you upload
- Check the official portal requirement before processing.
- Preview names, dates, seals, signatures, and marks.
- Keep the original file until your application is accepted.

Frequently asked questions
How do I compress my OBC or Caste certificate under 100KB?
Scan the certificate as a PDF, crop clean edges, upload it here, select 100KB, and verify that names and dates are visible before downloading.
Will a compressed certificate be rejected if the seal is faint?
Yes. Always check the final download. If the stamp or seal becomes unreadable, scan at a lower resolution or use 150 DPI and re-compress.
