Convert a PDF to grayscale

An ink-friendly black-and-white copy with exactly the same page sizes — for cheaper laser printing, consistent photocopies, or print shops that require grayscale files.

Your PDF is converted locally on your device. Nothing is uploaded, stored or logged.

How it works

  1. Drop your PDF.
  2. Pick a quality. High for print, Balanced for everyday use, Smallest when file size matters more than crispness.
  3. Convert & download. Colors become tonally-accurate grays (proper luminance weighting, not a flat average).

Frequently asked questions

Will the text still be selectable?

No — each page is re-rendered as a high-resolution grayscale image, so text becomes part of the picture. Keep your original for editing; use the grayscale copy for printing and sharing.

Why convert to grayscale at all?

Color pages often print through expensive color toner even when they "look" black. A true grayscale file guarantees the cheap black cartridge, gives photocopier-consistent results, and is required by some print services.

Does the file get smaller?

Usually, yes — grayscale JPEGs compress better than color. The result screen shows before/after sizes. For maximum shrinking, use Compress PDF with its grayscale mode.

Is my PDF uploaded?

No — rendering and conversion run entirely in your browser.
