About This PDF Tool
Many SSC, Railway, and government portals set small PDF limits to keep uploads fast and consistent. The issue usually appears at the final step of a form: your scan looks correct, but the portal rejects it because the PDF is above the allowed KB limit.
This tool focuses on scanned PDFs. A typical workflow is to scan one or two pages (ID proof, certificate, or form), then compress it close to the target and confirm that text is still readable. If your PDF contains many pages or high-resolution photos, the tool may only get close to 20KB; in that case, consider splitting the document or using a higher limit page first.
Common issues include unreadable text after aggressive compression and file-size “sticking” above the limit. When that happens, try a slightly higher target such as 50KB and check the exact portal rule before attempting 20KB again.
