Frequently Asked Questions
Is it safe to process confidential contracts or financial PDFs on Zeugly?
Yes. Every PDF operation—compression, merging, page splitting, OCR, and annotation—executes client-side via WebAssembly. Your sensitive files never upload to a cloud server.
Does compressing a PDF reduce text clarity or vector quality?
No. Our client-side compression downsamples embedded raster images and strips redundant metadata streams while preserving crisp vector text and embedded fonts.
Can I use these PDF utilities when working offline?
Yes. Once the page is loaded in your browser or installed as a Progressive Web App (PWA), all PDF operations execute offline without an active internet connection.
