How it works

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.
