Reverse page colors for an alternative reading copy
Read a simple light-background document in darker colors
A mostly textual white-background manual is uncomfortable to read, but a few pages contain color photographs. Try 150 dpi and inspect the text-heavy pages alongside the photos. Keep the original for the photographs and for printing; inversion changes all pixels, not just the background.

Options after selecting a fileFrequently asked questions
The details, when you need them.
Are photographs inverted too?
Yes. The transformation applies to all rendered page pixels.
Can I choose only the background?
No. This tool inverts the entire page.
An alternative appearance for reading
Inversion can make a light document appear dark, but it also changes photographs, logos and diagrams. It is not an intelligent dark mode that selectively preserves images. Check whether the result remains comfortable and understandable for your intended use.
Keep the original document
The output is rebuilt from rendered images. Text selection, links and form controls are not preserved, and file size can increase. Store the original for editing, printing or sharing when its original color meaning matters. You can try OCR on the result if searchable text is needed.
Check the saved result
Check photos, diagram colors and fine type. Keep the original for print or any workflow where original color meanings matter.
Photos and diagrams invert too
All rendered colors are inverted, including photos and logos. This is not selective dark mode; links, forms and selectable text are lost.
Photos look unnatural
Inversion applies to the entire page. Keep the original or use a reader with a suitable viewing mode instead.
