Grayscale PDF

Convert a PDF to grayscale or black and white. Pages are re-rendered as images, and you see the before and after file size before you keep the result.

Runs 100% in your browser — only same-origin app assets load, never your file.

or click to browse — files stay on your device

Keep this file on this device so I can come back to itOff by default. Ticking this stores a copy in your browser's own storage — never uploaded — which is deleted after 24 hours, when you untick this, or when you press Clear session.

Every page becomes an image. In the converted PDF the text is no longer selectable, searchable, or readable by a screen reader, and links and form fields are lost. Your original file is not changed — keep it if any of that matters.
