Frequently asked questions

How much smaller will my PDF get?
It depends on the content. PDFs full of high-resolution images shrink the most; text-only files are already compact and change less.
Will compression blur my text?
No. Text stays sharp and selectable — compression mainly optimizes the embedded images.
Is the compressor free?
Yes. Compress PDFs for free, with no account and no watermark.
Can I compress a scanned document?
Yes. Scanned PDFs are mostly images, so they usually see the biggest size reduction.
