Convert PDF to Dark Mode

Yes. Upload the PDF above, pick Smart Dark and a dark theme, and download the result. The converter turns the white page background dark and the black text light, while colored text, images and illustrations keep their look. It works online in any modern browser, with no app to install.

Open this page, drop in your PDF, choose Smart Dark (keeps colors) or Full Invert (flips everything), pick a theme like dark gray, black or sepia, and click Convert to dark mode. Check the before and after preview, then download your dark PDF. It takes about a minute.

Choose Smart Dark and the Black (OLED) theme. The white background of the PDF turns black and the black text turns white, while colored text and images keep their look. It works the same way for any white background PDF. If you want to print instead, use our PDF to black and white converter, which removes the colors and keeps the white page.

Yes. There's no watermark, no page limit and no account.

No. The conversion runs entirely in your browser. Your PDF never leaves your device, so it's safe for confidential documents.

Yes, in Smart Dark mode. Only white, black and gray are flipped. Red stays red and blue stays blue; very dark colors are brightened a little so they're readable on a dark page. Photos and illustrations stay exactly as they are, on a white background like in the original.

Yes. Ebooks, textbooks and study guides with hundreds of pages work fine. The whole book is converted in your browser, figures and photos stay original, and you can convert only certain chapters by entering a page range like 20-45.

Yes. Smart Dark changes the colors inside the PDF instead of turning pages into pictures, so text stays selectable and searchable. Scanned pages keep their existing text layer if they have one, for example after OCR.

Yes. Scanned pages are detected automatically and recolored pixel by pixel: the paper turns dark and colored ink stays colored.

Yes. Pages are processed one at a time to stay within phone memory limits. On iPhone, tap Save dark PDF and choose Save to Files or open it in Books. Very large scanned PDFs are faster on a computer.

The converter checks what's actually inside the file, not just its name. Ebooks in EPUB format are sometimes downloaded with a .pdf ending. Those aren't PDFs, so they can't be converted here. Open them in an ebook app like Apple Books, which has its own dark mode.

PDFs that need a password to open can't be converted. Remove the password first. PDFs that open without a password but have editing restrictions are converted page by page as images, so their text won't be selectable.

Full Invert uses a standard PDF blend effect that Chrome, Edge, Firefox, Safari, Adobe Acrobat and Apple Books support. A few very basic viewers ignore it and show the original colors. Smart Dark works in every viewer.

Better not. Dark pages use a lot of ink. Dark mode is made for reading on screens, especially at night. Keep the original PDF for printing.
