Reduce PDF file size for free, right in your browser. Great for scanned and image-heavy PDFs. Adjust quality, then download. No upload, fully private.
Compress PDF makes large PDF files smaller so they are easier to email, upload or store. It works entirely in your browser — your document is never sent to a server.
The tool re-renders each page as an image at the quality you choose, then rebuilds a lighter PDF. This shrinks scanned documents and image-heavy PDFs the most. Text remains perfectly readable, but note it becomes part of the page image rather than selectable text.
PDFs that are already optimized, or that contain only text, may not shrink much. This tool helps most with scanned pages and image-heavy documents. Try a lower quality or resolution.
No. Because each page is rebuilt as an image, text stays readable but is no longer selectable or searchable. If you need selectable text, keep the original.
No. Everything happens locally in your browser. Your file never leaves your device.
