PDF to black and white / no color

Remove the color from a PDF without turning its text into a blurry picture.

Quick answer

How do I convert a PDF to black and white?

Add your PDF, choose Grayscale or Black and white, then download the converted copy. Text, drawings and images lose their color, but text stays sharp and selectable because it is not turned into a picture. Black and white also turns scanned pages and photos into pure black and white, which suits scanned text and usually makes the file smaller. It runs in your browser, so the file is not uploaded.

Privacy by default

The conversion runs locally in this browser tab. Your PDF stays on your device while a black and white copy is created.

Why convert this way

Color out, quality kept

Grayscale or pure black and white

01

Text stays text

Colors are changed where the PDF defines them, so text stays sharp, selectable and searchable instead of becoming an image.

02

Grayscale or black and white

Keep smooth shades of gray, or make scanned pages and photos pure black and white.

03

Images, gradients and forms too

Photos, gradients, patterns, form fields and comments lose their color along with the text.

04

Smaller scans

Pure black and white images need far less data than color ones, so scanned documents usually shrink.

05

Works locally after the page loads

The PDF is converted in your browser tab and never sent to a server.

06

No account required

Open the tool and use it without registration or a subscription.

Grayscale, printing and file size

PDF to black and white FAQs

Grayscale, printing and file size

How do I convert a PDF to black and white?

Add the PDF, choose Grayscale or Black and white, and download the converted copy. Everything happens in your browser.

What is the difference between grayscale and black and white?

Grayscale turns every color into a shade of gray, which keeps photos and charts readable. Black and white also turns scanned pages and photos into pure black and white, which looks crisp for scanned text and makes the file smaller, but photos lose detail. Text and drawings become gray in both.

Will the text stay selectable?

Yes. Text is not turned into an image; only its color changes, so you can still select, search and copy it.

Will printing it save color ink?

The converted file has no color to print, so it prints in gray on any printer. Some color printers still mix gray from color inks; to avoid that, also choose grayscale or black ink only in the print settings.

Does it make the PDF smaller?

Often. Gray images hold a third of the data of color ones, and black and white scans shrink the most. A PDF that is mostly text changes little.

Is my PDF uploaded?

No. The file is converted in your browser tab and never leaves your device.

Verify it yourself

Your file is not uploaded. Here is how to check.

The core tools run inside your browser tab, so a document you open here is not sent to FreePDFKit or to anyone else. You can confirm that in about a minute.

  1. Step 1

    Open the tool and let it load

    Wait until the page has finished loading.

  2. Step 2

    Open your browser’s developer tools

    Press F12 (or Cmd+Option+I on a Mac) and switch to the Network tab.

  3. Step 3

    Run the tool on a test file

    Choose a non-sensitive file of the type the tool accepts and process it as usual.

  4. Step 4

    Look for a request that carries the file

    You will not find one. The page loads its own scripts, then the work happens in your browser.

What backs this up

  • Open-source libraries in the page. PDF handling uses libraries such as pdf-lib and Mozilla’s PDF.js, which run in your browser.
  • No PDF endpoint on the server. The only server routes are the contact form and the social-preview image generator.
  • A restrictive security policy. The site’s Content-Security-Policy limits the fetch and XHR connections page scripts can make to our own origin and Cloudflare’s anti-spam check, plus Google Analytics, which receives page views only.
