Free PDF Compressor
Reduce PDF file size in your browser. Best for scanned or image-heavy documents — see exact before/after numbers, not a promised percentage.
Compression re-renders each page as an image and rebuilds the PDF at your chosen quality — this shrinks image-heavy or scanned PDFs well, but the output text is no longer selectable or searchable. Not every PDF gets smaller; a small, already-efficient text PDF can end up larger.

Frequently Asked Questions
How does the compressor reduce file size?
It re-renders each page as an image at your chosen quality level and rebuilds the PDF from those images. This is especially effective for scanned documents and image-heavy PDFs.
Will the text in my PDF still be selectable afterward?
No. Because compression works by rasterizing each page, the output is pixels, not text — you lose text selection and search in the compressed file. If you need the text preserved, don't use this tool.
Will every PDF get smaller?
No. A PDF that's already small, text-only, or well-optimized can come out the same size or even larger after rasterization. The tool always shows the real before/after size so you can decide.
Are my files uploaded to a server?
No. Compression runs entirely in your browser.
