How to Compress PDF to 100KB
Compressing a PDF to 100KB is one of the most common requirements for Indian government recruitment portals. SSC, UPSC, IBPS, and many state PSC application forms have strict file size limits, often requiring documents under 100KB. Our free PDF compressor helps you reduce your PDF file size to meet these requirements. The tool works entirely in your browser — your documents never leave your device, ensuring complete privacy for sensitive certificates, marksheets, and identity proofs. Many candidates face rejection or failed uploads because their scanned documents exceed the 100KB limit. With our compressor, you can quickly optimize your PDFs to fit within the required size. The tool strips unnecessary metadata, removes duplicate objects, and streamlines the PDF structure. For best results when targeting 100KB: scan documents at 150-200 DPI instead of 300 DPI, use grayscale instead of color where possible, and ensure the scanned area doesn't include unnecessary margins. After scanning, use our compressor to further reduce the size. This tool is also valuable for professionals who need to email PDF attachments within size limits, upload documents to portals with restrictions, or share files via messaging apps with size constraints. The compression is quick, usually completing in just 2-3 seconds.
