How to Convert a PDF to Grayscale or Black and White
Written and fact-checked by The EditPDF AI Team
Whether you can get a grayscale PDF today depends entirely on where you're starting: scanning a physical page in grayscale is directly supported; converting a PDF you already have from color to grayscale is not currently a dedicated feature.
Scanning a physical document in grayscale
If you're starting from a physical page rather than an existing PDF, Scan to PDF includes a grayscale capture filter alongside Enhanced and Black & White modes — you choose it before capturing, and the page is saved in grayscale directly.
- 1Open Scan to PDF and select the Grayscale filter from the scan mode options.
- 2Capture the page with your phone or webcam camera as usual.
- 3Save — the resulting PDF page is already grayscale, with no separate conversion step needed.
Do you already have a color PDF you want converted to grayscale?
This is the harder case, and it's worth being direct about it: converting an existing color PDF to grayscale isn't currently a dedicated feature. The grayscale option lives specifically in the scanning capture step, not as a standalone file-conversion tool.
If the goal is simply a smaller, less colorful file for printing or sharing, PDF Compressor re-renders every page as a JPEG at your chosen quality level — it won't strip color specifically, but it does reduce file size, which is often the actual underlying reason grayscale gets requested in the first place.
When grayscale actually matters
- ·Printing costs — black-and-white printing is typically cheaper per page than color, even for a page that was only ever black text
- ·Consistency across scans — a batch of documents scanned by different people on different devices looks more uniform in grayscale
- ·Reducing file size — dropping color information can shrink a file, though direct compression is usually a bigger factor than color alone
