About the PDF Black & White Converter

The PDF Black & White Converter is a free, browser-based tool from Quenavo. Convert colorful PDFs to grayscale for cheaper printing and a consistent professional look. Quality and layout are preserved. Everything happens locally in your browser: the file you choose is read by JavaScript on your own device, processed in memory, and handed straight back to you — nothing is ever uploaded to a server.

Because Quenavo runs entirely in your browser, the pdf black & white converter works the same on Windows, macOS, Linux, ChromeOS, Android, and iOS. There is nothing to install, no account to create, and no watermark on your results. Enable JavaScript to use the tool interactively.

Your Privacy Comes First

Quenavo was built around one principle: your files are your business. The PDF Black & White Converter processes everything with client-side JavaScript inside your browser. Your files are never uploaded, never stored on a server, and never seen by anyone — including us. When you close the tab, nothing remains anywhere except the file you downloaded.
