Convert PDF to Grayscale

Remove colors from your document to save on expensive printer ink.

⚠️ Please Note

Converting a PDF to grayscale rasterizes its pages into images. After conversion, text on those pages can no longer be searched, selected, or copied.

Save Ink and Size

Color printer ink is notoriously expensive. When you need to print a massive 50-page report, lecture slides with heavy blue backgrounds, or tickets, printing in full color is a huge waste of money. The smartest solution is to convert PDF to grayscale before you even send it to the printer.

Our tool processes the entire document—including text, borders, and embedded images—and strips away the color data, leaving a perfectly readable black and white PDF. This ensures your printer will strictly use the cheap black cartridge, preventing it from sneaking in colored ink to make 'rich black'.

As a bonus, stripping out complex color data often reduces the overall file size. And just like all our tools, this conversion happens locally in your web browser. Your proprietary business reports are never uploaded to the cloud, ensuring maximum data privacy.

Frequently Asked Questions

Will photographs look bad in grayscale?

No, photographs are converted using proper luminance mapping. They will look like high-quality black-and-white photos, maintaining their contrast and detail.

Can I just tell my printer to print in black and white?

You can, but many modern printers use a technique called 'composite black', where they mix cyan, magenta, and yellow ink to make black. By converting the file to true grayscale beforehand, you force the printer to only use the black cartridge.
