Compress PDF
Shrink a PDF by recompressing its embedded photos — entirely in your browser.
Scanned documents and image-heavy PDFs can balloon in size, making them awkward to email or upload. This tool recompresses the photos embedded in your PDF to shrink the file, without sending it anywhere but your own browser.

Frequently Asked Questions
Will compressing reduce text quality?
No — text and vector content stay sharp. Compression only re-encodes the embedded photos.
How much smaller will my file get?
It depends on the PDF — files with large, high-resolution photos or scans see the biggest reduction; text-only PDFs shrink very little since there's nothing to recompress.
