Frequently asked questions
Does compression work on every PDF?
Compression is most useful for image-heavy PDFs such as scans and photo-based documents.
Is the PDF uploaded?
The tool is designed to perform processing in your browser.
Will compression always make a PDF smaller?
Not every PDF shrinks substantially; already-optimized or mostly-text PDFs may see limited savings.
