Upload a color PDF and convert each page to grayscale by re-rendering page images. Useful for print drafts. Text will no longer be selectable. Processing runs locally.
Pages are re-rendered as images. Vector text and forms are flattened.
How to use this tool
1. Upload a color PDF. 2. Start grayscale conversion—each page is re-rendered without color. 3. Monitor progress for large files. 4. Compare file size in the results if shown. 5. Download the grayscale copy for print drafts or fax-friendly sharing.
Worked example
Example: a 12-page color brochure converted to grayscale often shrinks visually complex pages and is easier to proof on a black-and-white office printer.
