If you are a candidate you have scanned your certificates perfectly, but the government portal rejects them because they exceed 200KB or 500KB.
Most users think compression just "zips" a file. In reality, PDF compression involves complex algorithms that target three areas of the file structure:
Portals like often have a strict limit (e.g., 200KB). If you compress too much, your signature or community certificate becomes a blurry mess, leading to application rejection.
At PDFBlink, we use a "Smart Compression" algorithm. Instead of a blanket reduction, our tool analyzes the text-to-image ratio. We ensure that text remains sharp—essential for hall tickets and mark sheets—while aggressively optimizing the "white space" and background metadata that you don't need.
Security is non-negotiable when dealing with government IDs. I designed this tool using WebAssembly. Your certificates are never uploaded to a server; the compression happens entirely inside your browser. This is the highest standard of data privacy in the IT industry today.
Use our secure, browser-based tool to get under the limit in seconds.
Open PDFBlink Compressor →What is the best format for scanning certificates?
Scan as a PDF at 300 DPI initially, then use PDFBlink to bring the size down to the portal's specific limit.
Will the portal reject a compressed PDF?
No, as long as the text is legible. Our "Smart Compression" is designed to keep your name, date of birth, and register numbers crystal clear.
