Compress PDF files, free and without uploading
Large PDFs are usually large because of the photos inside them. This tool re-compresses only those images and leaves text, fonts and drawings untouched, so the document looks the same and stays searchable. If a file can’t get smaller, you keep the original.

Questions, answered
- Are my files uploaded?
- No. Everything runs in your browser on this device; the files never reach a server.
- Why did my PDF barely shrink?
- Text-only PDFs are already small. Scans and PDFs full of photos shrink the most.
- Will the text still be searchable?
- Yes. Only images are re-compressed; text and fonts are not touched.
