What is the PDF Compressor Tool?

The PDF Compressor reduces the file size of PDF documents without noticeably diminishing document readability or image quality.

Whether you need to shrink an invoice to send via email, upload a thesis under university size caps, or submit a contract under a 2MB portal limit, our tool optimizes internal font streams and image resolutions client-side.

Frequently asked questions

Does compressing a PDF reduce text sharpness?
No. Standard PDF text vectors and fonts remain crystal sharp. Compression primarily optimizes redundant font definitions and scales down high-resolution embedded images to screen-friendly DPIs.
Is it safe to compress confidential legal or financial PDFs here?
Yes. Our client-side compression engine executes locally in your browser sandbox using WebAssembly/JavaScript. Your documents never touch our servers.
How much file size reduction can I expect?
PDFs with scanned photos or high-res images can often be reduced by 50% to 80%. Text-only PDFs are already compact, so reductions range from 10% to 30%.
