Frequently asked questions
Why did my scanned PDF barely get smaller?
The current tool optimizes the file structure without recompressing embedded images. PDFs made mostly of photos or scanned pages may get only slightly smaller, or stay the same size.
Does this tool turn pages into images?
No. The current optimization rewrites the PDF structure with PDF-lib. Check advanced features, such as forms and annotations, in the result.
Can I use a password-protected or digitally signed PDF?
This version rejects encrypted PDFs and files with a detected signature structure. Changing a signed document may affect the signature’s validity.
