Frequently Asked Questions

Will text stay selectable?

This tool rasterizes pages to images, so text may not remain selectable after compression. Use it when file size matters more than editability.

How much can I reduce the size?

Results depend on the original PDF. Image-heavy or scanned documents compress the most; already-optimized PDFs may see little change.
