About PDF Size Compressor
Large PDF files frequently exceed upload limits on email servers, job boards, and government portals. Our client-side compressor strips redundant metadata objects and optimizes embedded graphics.
Because processing happens entirely inside your browser using pdf-lib, private bank statements, contracts, and tax documents remain 100% confidential.
Common Use Cases
- Downsizing PDF resumes and portfolios for job applications.
- Compressing scanned tax forms and identity documents for upload portals.
- Reducing large PDF reports to attach easily in standard emails.
Private & Secure Browser Processing
All processing is executed locally in your browser. Files are never transmitted or stored on remote servers.
