FAQ
Is my PDF uploaded to a server?
No. Compression runs entirely in your browser. Your file never leaves your device.
Why did my file get bigger?
This tool re-encodes pages as images, which shrinks scanned or photo-heavy PDFs a lot but can enlarge simple text-only PDFs. Use a lighter quality or keep the original in that case.
Will the text still be selectable?
No. Because pages are rebuilt as images, text becomes part of the image and can no longer be selected or searched.
