PDF Dark Mode — frequently asked questions

Why not just invert colours?+

A plain invert turns blue links orange. Dark mode flips only lightness, so headings, links and charts stay the colour you expect.

Is text still selectable?+

No — pages become flat images.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The AI tools that used to send extracted text to a server are currently disabled.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
