Why Use Our PDF Compressor for Exam Uploads?
Many exam portals like Kerala PSC, UPSC, SSC, and banking exams have strict file size limits for document uploads. Our PDF compressor helps you meet these requirements without losing document quality.
The compression works by optimizing embedded images in your PDF while keeping text crisp and readable. Perfect for scanned documents, certificates, and mark sheets.
Common File Size Limits by Exam Portal
Different exam portals have varying requirements: Kerala PSC typically limits uploads to 100-200KB, while UPSC allows up to 300KB for documents. SSC CGL/CHSL portals usually accept 200-500KB files, and IBPS banking exams commonly have a 500KB limit.
Our compressor lets you target any specific size – whether you need to reduce a 5MB scanned certificate to 100KB or compress a multi-page mark sheet to 500KB. The intelligent compression algorithm prioritizes visual quality, ensuring your documents remain legible even at smaller file sizes.
For scanned documents with lots of images, you can achieve 70-90% size reduction. Text-heavy PDFs typically compress by 30-50%. Use the quality slider to find the right balance between file size and visual clarity for your specific needs.
