Frequently asked questions
How much smaller will my PDF get?
Scanned and image-heavy PDFs usually shrink by 50–90%. PDFs that are mostly text are already compact and shrink less.
Will compression reduce quality?
Recommended keeps images sharp for screen reading and printing. Extreme lowers image resolution for the smallest file. Lossless never changes image quality.
Is the text still selectable after compression?
Yes. Only images are re-compressed; text, links and fonts stay exactly as they were.
Are my files uploaded to a server?
No. PDFCart compresses PDFs locally in your browser using WebAssembly.
