About PDF Compressor
Large PDF files are a common problem when emailing contracts, reports, or application documents. The PDF Compressor reduces file size directly in your browser using adjustable compression levels. Choose Light, Standard, or Maximum, then fine-tune the result with advanced options for image quality, unused elements, fonts, and metadata removal. A preview shows the estimated size reduction before you commit, and Standard compression typically cuts file size by 50-70% with minimal quality loss. Because the entire process runs on your own device, confidential contracts, financial records, and medical documents are never uploaded to a server, so sensitive pages stay under your control from start to finish.

Frequently Asked Questions
Where does my PDF go when I compress it?
Nowhere. The compressor runs entirely in your browser and never uploads your file to a server. Your document stays on your device the whole time, which matters for confidential contracts, financial records, and medical documents.
How much can I reduce my PDF's file size?
With Standard compression you can typically expect a 50-70% reduction with minimal quality loss. Image-heavy PDFs compress much more than text-only documents, while Maximum compression may reduce image quality noticeably.
Is the PDF Compressor free? Do I need an account?
It is completely free with no signup, subscription, or account required. There are no usage limits or watermarks, and no file ever leaves your device.
