Frequently asked questions
- Is my PDF uploaded to a server?
- No. Compression happens entirely in your browser, so sensitive documents never leave your device.
- How small can the file get?
- It depends on the content — image-heavy PDFs shrink the most. You can choose a stronger setting if you need to hit a specific size like under 100 KB or 2 MB.
- Will the text stay selectable?
- Heavier compression re-renders pages and can affect text selectability; choose a lighter setting if you need the text layer preserved.
- Is there a size limit?
- No fixed limit — you're only bounded by your device's available memory, since the work is done locally.
