About this tool

Reduce PDF file size locally by rebuilding scanned pages as compressed JPEG images. Use it without creating an account. Results are available immediately, and inputs are not saved between visits.

Does this send my input to a server?

Inputs are processed locally. Optional Analytics sends page statistics only after consent; tool inputs and files are excluded.

Will this PDF compressor preserve selectable text?

No. This mode rebuilds each page as a JPEG image inside a PDF. It can help image-heavy scanned documents, but removes selectable text, links, forms and signatures. A smaller result is not guaranteed.
