Grayscale PDF
Convert every page of a PDF to grayscale locally
Convert every page of a PDF to grayscale by rendering it, desaturating the result, and rebuilding a new PDF. Processing happens entirely in your browser, and the result is a rasterized, image-based PDF.
No file selected.
Every page is rendered to an image and desaturated, then rebuilt into a new PDF. Selectable text and vector graphics become a flat picture in the result.
Everything on this page is processed in your browser. Nothing is uploaded.
What this tool does
This tool renders each page of your PDF onto a canvas, applies a standard grayscale conversion to its pixels, and rebuilds a new PDF from the resulting images. It is useful for previewing how a document will look in black and white or preparing it for grayscale printing. Because each page is rendered as an image, selectable text and vector graphics in the result become a flat picture.
How to use it
- Choose a PDF file from your device.
- Press Convert to grayscale.
- Download the grayscale PDF.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Does the text stay selectable?
- No. Every page is rendered to an image before it is desaturated, so the resulting PDF is a rasterized picture of each page rather than text and vector graphics.
- Is my PDF uploaded to convert it?
- No. Rendering and rebuilding both happen in your browser.
- Will the file size change?
- It usually will, since the output is a rebuilt, image-based PDF rather than the original document structure.
