FAQ

Frequently Asked Questions

Why convert a PDF to grayscale?

Grayscale PDFs are smaller in file size, use less ink when printed, and are often required for official document submissions. Black and white documents also load faster online.

Will this affect the text readability?

No – text remains crisp and readable. Only colors are removed. Black text stays black, and colored elements become appropriate shades of gray.

Is my PDF uploaded to a server?

No – all conversion happens directly in your browser using pdf-lib. Your file never leaves your device.

Can I convert only certain pages?

The current version converts the entire document. For page-specific conversions, use our Split PDF tool first to extract pages.

Is this tool free?

Yes – completely free with no limitations. No sign-up, no watermarks, no hidden costs.
