Guides/Invert PDF colours
How to invert pdf colours free — no upload, no watermark
Pages are rendered, colour-mapped, and re-embedded. Text on those pages becomes part of the image. This guide is for ProMaxPDF on promaxpdf.pro. The file never leaves your browser — students and businesses use the same local engine.
- Open the tool. No account. The page loads the editor in your browser.
- Add files. Drop files onto the page. They are read locally and never uploaded.
- Invert. Pick a mode. Pages are rasterized with the new colours.
- Download. The result is saved to your device. Nothing is stored on a server.
FAQ
Is text still selectable?
Not after invert — pages are images so the colour change is permanent.
Are files uploaded?
No.
Why rasterize?
True vector recolor of arbitrary PDFs is not portable in the browser.
