FAQ
How does it compress?
Each page is re-rendered as an optimized JPEG image at reduced resolution. This works brilliantly for scanned documents and image-heavy PDFs.
Any downside?
Because pages become images, text is no longer selectable/searchable in the compressed copy. Keep the original for editing; use the compressed one for uploads.
Is my PDF uploaded?
No — compression happens entirely in your browser using open-source pdf.js. Nothing is sent to any server.
