FAQ

Is my PDF uploaded to your server?

No. PDF Dark runs 100% in your browser. We literally don't have a server that receives your file.

How can I print a PDF in dark mode?

Click download after conversion, then print the downloaded dark PDF from any reader.

Does this work on iPhone or iPad?

Yes. Safari on iOS can drop/upload PDFs directly to this page—no app install needed.

How is this different from a browser dark-mode extension?

Most dark-mode extensions invert everything including images. PDF Dark detects image regions and keeps them in their original colors, so photos and charts look right.

Does it work for scanned PDFs?

Yes. We render each page as an image and apply theme inversion. Handwriting and scanned text become light-on-dark automatically.
