Turn a color PDF into grayscale or high-contrast black and white without uploading the file. PDFPeach converts pages in your browser so print jobs, archives, and drafts look consistent — free and private.
Choose Grayscale for soft shades across the whole page, or Black for a print-like high-contrast look. Photos stay as smooth grayscale so they are not crushed into harsh black-and-white dots.
How to make a PDF grayscale
- Drop a PDF into the uploader.
- Choose Grayscale or Black mode and preview the result.
- Download the converted PDF.
Why convert to grayscale on PDFPeach
- Two clear modes. Soft grayscale for reading and archives; Black for high-contrast, ink-friendly pages.
- Photo-friendly. Detected images remain smooth grayscale even in Black mode, so faces and photos do not posterize.
- Instant preview. Thumbnails update as you switch modes before you download.
- Private. PDFPeach never uploads your document.
When to use Grayscale PDF
- Prepare color decks for black-and-white office printers.
- Normalize mixed color scans into a consistent gray archive.
- Reduce visual noise before sharing drafts that do not need color.
- Create a high-contrast Black version for clearer photocopies of text-heavy pages.

What changes in the file
Pages are converted to images for the color change. Text is no longer selectable in the downloaded PDF — treat the result as a visual/print document, not an editable text PDF.
Privacy
All processing stays in your browser. No account, no upload, free on PDFPeach.
Frequently asked questions
What is the difference between Grayscale and Black?
Grayscale converts the whole page to shades of gray. Black makes text and page content high-contrast black and white, while detected images remain smooth grayscale.
Will I still be able to select text?
No. Each page becomes an image, so text is not selectable in the downloaded PDF.
Do photos become harsh black and white?
No. Photos stay as smooth grayscale so they do not get crushed into harsh black-and-white.
Are my files uploaded?
No. Grayscale conversion on PDFPeach runs entirely in your browser.
