Frequently asked questions
How does the compression work?
It re-renders each page as a compressed image and rebuilds the PDF, which dramatically shrinks scanned and image-heavy files. Selectable text becomes part of the image.
Is my PDF uploaded?
No — everything is processed locally in your browser, so your document never leaves your device.
