How it works
Add your PDF
One or more files.
Pick a colour
Soft cream is gentle for long reading.

Check the preview and save.
Content stays as it is
The colour is painted under the page content, so text and drawings are not changed and stay selectable.
Scanned pages are pictures that cover the whole page, so the colour does not show on them.
Private
Your file is processed inside your browser with the open-source pdf-lib library. It is never uploaded, and nothing is saved after you close the page.
Questions
Are my files uploaded?
No. The tool runs inside your browser, so your files are opened and changed on your own device. They are never sent to us or to anyone else.
Why do scanned pages not change?
A scan is a picture that covers the page, including its white paper. Use Adjust PDF colours instead.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
