Frequently asked questions
Is Colour Inverter free to use?
Yes. Colour Inverter on ToolsPilot is 100% free with no account, no watermark and no daily limits for everyday use.
Are my files private and secure?
Colour Inverter runs entirely in your browser, so your file never leaves your device — nothing is uploaded to any server.
Do I need to install any software?
No. Colour Inverter works online in any modern browser on Windows, macOS, Linux, Android and iOS — there is nothing to download or install.
Can I invert the colours of a PDF?
Yes — upload a PDF and every page is inverted into a dark-mode negative automatically. You can also invert ordinary images like JPG and PNG.
Will the inverted PDF still have selectable text?
The inverted PDF is rebuilt from high-resolution images of each page, so it is a visual negative and the text is no longer selectable.
