CSMC All Group C Posts PDF Compressor & Merger

Tool 1: Certificate to PDF Converter
Tool 2: Multi-Page PDF Merge & Compressor
100% Private: All processing happens in your browser. Files never leave your device.
How this tool works
This tool redraws each page as a compressed image and merges everything into one PDF under 200 KB, the CSMC limit for All Group C Posts documents. If the first result is too large, it lowers quality and resolution step by step until the file fits. Text in the result cannot be selected, which does not affect the upload.

Common All Group C Posts PDF Upload Errors
"PDF exceeds 200KB size limit"
The CSMC portal blocks certificate uploads above 200KB. Our compressor automatically reduces file size while preserving readability.
"Multiple marksheets rejected — only single PDF accepted"
Many portals require all semester marksheets merged into one PDF. Use our merger tool above to combine multiple pages into a single file.
"Uploaded image instead of PDF"
Some portals only accept PDF format for certificates. Use our converter above to turn JPG/PNG images into properly formatted PDFs.
