Free PDF Compressor
Shrink a PDF in your browser by re-rendering pages as compressed images at a chosen quality and resolution. Best for scans/image-heavy PDFs. Nothing is uploaded.
PDF Compressor
Files you add are processed entirely in your browser — nothing is uploaded to our servers.
How it's calculated
- • Renders each page with pdf.js, re-encodes it as a JPEG at your chosen quality and resolution, then rebuilds the PDF with pdf-lib — all in your browser (pinned CDN libraries).
- • Because pages become images, selectable text and bookmarks are lost. This works best for scanned or image-heavy PDFs; text-only PDFs may not shrink (or could grow).
