About This PDF Tool
A 50KB target is a practical middle ground for many online forms. It reduces file size enough to meet strict upload requirements while keeping scanned text readable, which is important for certificates and documents submitted during recruitment or verification.
If you are compressing a scanned PDF for SSC or Railway portals, start here when the upload limit is unclear or when 20KB makes the document too blurry. After compression, zoom into the preview on your device to confirm names, dates, and stamp text remain legible.
If the PDF is still above 50KB, it usually means the scan has heavy noise, too many pages, or very high resolution. Re-scan in grayscale or lower DPI (if possible) and compress again for better results.
