Reduce PDF Size: what you need to know
Most of a PDF's size comes from photos and scanned pages. FilesForU recompresses those images to a sensible resolution while leaving text and vector graphics untouched, so the document stays sharp and readable.
Start with Recommended. If the file is still too big, try Strong; if you need the best image quality, choose Light. You'll see exactly how much smaller the file became.

Questions & answers
Will compressing make my text blurry?
No. Only images are recompressed; text and drawings stay exactly as they were.
Why didn't my PDF get much smaller?
PDFs that are mostly text are already small. Big savings come from files with photos or scans.
Can I compress several PDFs?
Compress one file at a time, then click Start over for the next.
Are my files uploaded to your server?
No. This tool runs entirely inside your browser, so your files stay on your device. FilesForU never receives, stores or sees them.

Yes. Every tool is free with a free account — no daily limit, no watermarks, and files up to 500 MB.
