Features
Rendered in shades of grey
All colours are converted to consistent grey levels, preserving contrast and keeping text and graphics perfectly legible.
Cheaper printing
A colourless document uses only black ink, cutting the cost per page and sparing your colour cartridges entirely.
Often smaller files
Removing colour information frequently shrinks the PDF, handy for archiving or sending the document by email.
Fully local conversion
Processing happens in your browser; no confidential document is uploaded or kept on any server at any point.
Use cases
- Print a report without wasting colour ink.
- Standardise documents for plain archiving.

Your files never leave your device
Unlike most online PDF tools that upload your files to their servers, all processing happens right here, in your browser. No document is ever sent, stored or analyzed remotely: it's free, no sign-up, and private by design.
Frequently asked questions
- Does text stay selectable?
- No. Colour removal is applied to the rendered page, so it is rasterized and the text becomes a non-selectable image.
- Will the file be smaller?
- Often yes, since colour information is removed; the exact saving depends on the original content.
- Can I revert to colour?
- No, the conversion is permanent on the generated file; keep your original colour version if you may need it.
- Are my files uploaded to a server?
- No. All processing happens in your browser: your files never leave your device.
