How PDF Compressor works

Reduce PDF file size privately in your browser with no server upload. Best for PDFs that can be structurally optimized.

What you provide
A PDF document.
What FileFix returns
A structurally optimized PDF when the rewritten file is smaller, otherwise the original-sized result with an honest explanation.
Practical limit
Browser-side structural optimization cannot substantially shrink PDFs dominated by already-compressed images or scanned pages.
