Why Compress and Merge PDFs Online?

Meet Strict Government Portal File Size Limits

Online application portals for scholarships, job recruitments, and tax filings often impose strict size ceilings (such as 100KB or 200KB) on PDF documents. When multiple scanned documents exceed these limits, users struggle to upload them successfully.

Our Compress & Merge PDF Tool allows you to select up to 3 PDF documents simultaneously, scale them down to an exact target KB size, and combine them into a single streamlined file without losing text legibility.

100% Privacy Guaranteed: All PDF parsing, canvas rendering, and compression occur locally inside your browser using client-side libraries. Your files never touch a remote server.
