ANSWERS BEFORE YOU START

Frequently asked questions

How do I compress a PDF to 100KB?

Choose Compress PDF, select the under 100 KB target, and process it locally. The strongest compression rasterises pages, so text becomes non-selectable.

Will compression keep selectable text?

Low and medium modes preserve the PDF structure when possible. Under-target raster compression converts page content to JPEG images and text is no longer selectable.

Does compression upload my file?

No. Compression runs entirely in your browser with a progress bar.
