Frequently Asked Questions (FAQ)

Are my PDFs uploaded to a server?

No. All processing happens entirely within your device's web browser. Your documents never leave your device or touch our servers.

Does compression reduce quality?

Yes. To reliably hit your target size, each page is re-rendered as an optimized image. This slightly reduces sharpness and makes text non-selectable, but it preserves the layout and appearance of the document.

Can I compress multiple PDFs at once?

Yes. Add multiple PDFs, compress them all in one go, and download the results individually or bundled together in a single ZIP archive.
