How PDF to grayscale works

Render pages locally with PDF.js, convert pixels to grayscale, and embed those images in a new PDF.

Processing uses bundled libraries in this browser. The download contains the generated file, rather than a link to a conversion service.

How to create grayscale PDF

Start with the supported input, then check the generated result.

Choose the supported file

Choose PDF document. The file stays in this browser; it is not saved by the page.

When to use PDF to grayscale

These workflows use the formats and behavior supported by this implementation.

Prepare an image-only monochrome copy

Make a separate grayscale copy while keeping the original PDF. This output stores rendered page images rather than editable page content.

Source text lines represented as large readable document shapes. — Work with your source text. Concept illustration.

Review pages with grayscale pixels

Check colored areas in the generated pages. Pixel conversion produces neutral grayscale values, but it does not simulate every printer’s output.

Text documents with highlighted lines for comparison and review. — Compare and review text. Concept illustration.

Make a copy at a chosen resolution

Choose a DPI that balances raster detail and file size. Searchable text, links and forms are removed at every supported resolution.
