How do I invert PDF colors online?

Drop the PDF here, click Invert, and download. The whole inversion runs in your browser, your PDF is never uploaded to a server.

Can I invert PDF colors for printing on dark paper?

Yes, that's one of the most popular use cases. Inverting first lets you print white text on dark backgrounds, which can dramatically reduce ink usage on text-heavy documents.

What's the difference between inverted PDF and dark-mode PDF?

Dark mode in a PDF reader changes how YOU see it. Inverting a PDF changes the file itself, so it stays dark for anyone who opens it, on any reader.

What happens to images in the PDF?

Image colors are inverted along with text. Photos look weird inverted; the tool works best on text-heavy PDFs like papers, ebooks, contracts, and code listings.

Will text stay selectable?

We rasterize pages to apply the inversion, so the output is image-based. Text becomes non-selectable. For selectable inverted text, change your PDF reader's view settings instead.

Will color inversion change the page size?

No, output PDF page dimensions match the input exactly. Only the colors change.

Is this PDF color inverter really free?

Yes, no signup, no watermark, no daily limits, no upload. Works offline once the page has loaded.

Does this work for invert PDF colours (UK spelling) too?

Yes, same tool, same result, regardless of spelling.
