Frequently asked questions
How does compression work?
Photos and scans inside the PDF are re-encoded at a lower quality and resolution, and the file structure is optimized. Text, fonts and vector graphics are left untouched, so text stays selectable.
What does Maximum reduction do?
It turns every page into an image. That can shrink stubborn files further, but text can no longer be selected or searched. Run OCR afterwards if you need text back.
Why didn't my file get smaller?
PDFs that are mostly text are already tiny, and some files are already well optimized. When there's nothing to gain, we tell you rather than hand back a bigger file.
Are my files uploaded anywhere?
No. This tool runs entirely in your browser. Your files never leave your device and nothing is stored.
