How it works

The tool finds every piece of text in the PDF and changes the colour it is drawn in, leaving shapes, lines and pictures alone.

Text that is part of a picture, such as a scanned page or a screenshot, isn't real text, so its colour can't be changed this way.

Tip: Want a softer look for printing? Dark grey text uses less ink than black.

Your files stay on your device

Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.

Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.

Frequently asked questions

Why didn't the text in my scan change?

Scanned text is part of a picture, not real text.

Can I change only black text?

Yes. "Only change dark text" is on by default.

Can I change the background too?

Yes, with Change PDF Background Colour.

Is it free?

Yes. There is no sign-up, no limit on files and no watermark.

Are my files uploaded?

No. The tool runs inside your web browser and works on the file on your own device. Nothing is sent to a server, so private documents stay private.
