Frequently asked questions
How does browser PDF compression work?
PicFlow renders each PDF page and rebuilds it with compressed page images.
Will every PDF become smaller?
No. Text-heavy, encrypted, or already optimized PDFs may have limited savings.
Does PicFlow upload my PDF?
No. PDF rendering and generation happen in your browser.
