Frequently asked questions
How much smaller will my file get?
It depends on the file. PDFs with unoptimized structure shrink noticeably; already-optimized or image-heavy PDFs may shrink only slightly. The tool always shows both sizes honestly.
Does compression reduce quality?
No. This optimization only reorganizes how the file is stored; page content is preserved.
Are my files uploaded?
No. Compression runs entirely in your browser.
