Convert PDF to Grayscale (Black & White)
Convert every page of a PDF to grayscale — useful for printer-friendly handouts and removing color from drafts. The tool converts every page to an image, so the output looks identical but text is no longer selectable. Free, in-browser, and no signup — your file stays on your device.

How to use convert pdf to grayscale (black & white)
Open your PDF
Drag and drop your PDF onto the upload area, or click to choose a file. The file stays on your device — there is no server upload.
Convert each page to grayscale
USA Sky PDF renders every page in your browser, applies the standard ITU-R BT.601 luma formula to each pixel, and re-embeds the result as a JPEG. Color drains uniformly to neutral grays — what professional design tools call a true grayscale conversion.
Download the grayscale PDF
Click Download to save the new .pdf to your device. Every page now looks identical in shape and layout, just rendered in shades of gray.
Why use USA Sky PDF
Your file stays on your device
Nothing is uploaded. The grayscale conversion runs entirely in your browser, and the new file is saved straight to your downloads folder.
Standard ITU-R BT.601 luma
Pixels are weighted 30% red + 59% green + 11% blue — the broadcast standard for color-to-grayscale conversion. Skin tones, text, photos, and graphics all convert cleanly without the muddy result simple averaging produces.
Free with no signup
No account, no email, no watermarks. There's nothing to upgrade for this tool because nothing leaves your device.
Frequently asked questions
Is grayscale conversion really free?
Yes. Free with no signup and no per-conversion limit.
Does the file leave my computer?
No. Conversion runs entirely in your browser. USA Sky PDF's servers never see your PDF for this tool.
Will my text still be selectable after grayscale conversion?
No. To convert color reliably, the tool rasterizes every page — that is, it re-renders each page to an image (JPEG) and re-wraps it in a PDF. The result looks identical, but text is now part of the image rather than selectable characters. If you need both grayscale AND selectable text, you'd need a tool that walks each text object and overrides its color — which doesn't exist in our toolset today.
What happens to my form fields?
Form fields are destroyed. AcroForm widgets are interactive layers; once a page becomes an image, those interactive layers are gone — the form is baked into the picture. If you need to keep the form fillable, don't grayscale until after recipients have filled it in.
Will the file get smaller?
Usually not — and often it gets larger. Vector text in a typical PDF compresses much smaller than the same text rendered as a JPEG. Grayscale is for visual appearance, not for shrinkage. If you need a smaller file, use the Compress tool.
