How to PDF to BMP with PrivaTools

1. Upload a PDF — Drop a PDF up to 500 MB.
2. Choose DPI — Higher DPI gives sharper output. 150 DPI for screen, 300 for print, 600 for archival.
3. Download a ZIP of BMPs — Each page becomes one BMP file. BMP is uncompressed so files are LARGE — typically 5-30 MB per page at 300 DPI.

Frequently Asked Questions

Why are BMPs so much larger than PNG?

BMP stores every pixel uncompressed. PNG losslessly compresses to ~20% the size. Use BMP only when you specifically need uncompressed pixel data.

What's BMP good for?

Legacy Windows software that doesn't support modern formats; embedded systems; precise pixel manipulation.

Can I get just one page as BMP?

Extract that page first with Extract Pages, then convert.
