Why a reading palette works better
A dark page should calm the canvas—not scramble the document.
Simple screen inversion treats every pixel the same. This tool gives document backgrounds, text, and colorful regions different jobs.
Keep color recognizable
Auto mode leaves high-chroma pixels closer to their source colors instead of turning every photo into a negative.
Choose true black only when useful
OLED Black is available for supported displays; Comfortable Dark is the calmer default for most documents.
The three reading results
Pick the page atmosphere—not just “dark.”
These swatches match the actual background and foreground colors used by the converter.

What Auto mode actually does
Photo protection is a pixel rule—not object recognition.
The preview is the source of truth, especially for diagrams, scientific imagery, screenshots, and colored text.
- 01
Measure color variation
High-chroma pixels can stay close to their original colors in Auto mode.
- 02
Map document tones
Low-chroma paper and ink are mapped into the selected background and foreground pair.
- 03
Let the preview override the guess
Switch Photo handling to preserve or invert when the automatic result is not right for that document.
Before you convert
PDF dark mode questions
Can I read the converted PDF offline?
Yes. The result is a separate PDF file you can keep and open in another compatible reader or device.
Will text, links, and forms remain interactive?
Not in the current export path. Converted pages are rasterized for predictable appearance, so keep the original for search, copying, links, forms, and editing.
Which preset should I start with?
Start with Comfortable Dark. Try OLED Black for a true-black display or Warm Night when you prefer amber text.
