Why this works
Render each page of a PDF as a BMP bitmap image \u2014 useful for legacy Windows systems, industrial control software, and specialised workflows that still require BMP input.
BMP (Windows Bitmap) is rare in modern workflows but persists in specific niches. PDF to BMP exists for those niches: older Windows-only document-management systems that haven\u2019t added support for newer image formats; industrial control software with hard-coded BMP input requirements; specialised imaging pipelines that standardised on BMP decades ago; legacy government and archival systems where BMP was the original spec.
For modern workflows, PDF to PNG or PDF to JPG is almost always the better choice \u2014 PNG has the same lossless quality at a fraction of the file size, JPG is even smaller for photographic content, and both are universally readable on every operating system. BMP files are large (uncompressed pixel data, no transparency support) and only well-supported on Windows.
Use this tool when downstream consumers specifically require BMP. Don\u2019t use it just to render PDF pages as images \u2014 PNG or JPG will produce smaller, more portable output for any other purpose.
The output is one BMP per page, packaged as a ZIP. Resolution options are the same as PDF to JPG: High (300 DPI, print-grade), Standard (150 DPI, screen-grade), Web (72 DPI, thumbnails). At High quality each BMP can be 5\u201310 MB even for a single page, so for multi-page documents the ZIP gets large quickly.
If you have a BMP requirement but file size is also a constraint, drop the resolution to Standard or Web. If you can negotiate the requirement away \u2014 ask whether PNG would work instead \u2014 do that; modern software almost always accepts PNG transparently. PDF to BMP is here for the cases where you can\u2019t change the downstream consumer.
How it works
-
1Confirm you need BMPFor most uses, PDF to PNG or PDF to JPG is a better choice \u2014 smaller files, broader compatibility. Use BMP only when downstream explicitly requires it.

Real-world uses
Industrial QA
Inspection software that only accepts BMP input for archival photo proof.
Legacy archives
Government or corporate systems that standardised on BMP and haven\u2019t modernised.
Specialised imaging
Scientific or medical imaging tools with hard-coded BMP support.
Forensic preservation
Workflows that demand uncompressed image data for evidence-chain reasons.
Common questions
Why is BMP still used anywhere?
Niche legacy systems \u2014 older Windows document management, industrial control software, government archival systems that mandated BMP decades ago. For any modern workflow, PNG or JPG is a better choice.
Should I really use BMP over PNG?
Almost never, unless a downstream consumer explicitly requires BMP. PNG has the same lossless quality with much smaller files and broader compatibility. Ask whether the consumer accepts PNG before defaulting to BMP.
Will the output ZIP be huge?
At High quality, yes \u2014 BMPs are uncompressed pixel data. A 10-page PDF at 300 DPI can produce a 50+ MB ZIP. Drop to Standard or Web if file size matters.
Does BMP preserve transparency?
No \u2014 BMP doesn\u2019t support transparency. Any transparent regions in the source PDF render as solid white in the BMP output. For transparency-preserving output, use PDF to PNG.
Is the format truly lossless?
Yes. BMP stores raw pixel data with no compression \u2014 the image inside is bit-perfect. The trade-off is file size: BMPs are roughly 10x larger than equivalent PNGs at the same resolution and content.
Can I get one specific page as BMP?
Use Extract Pages first to pull the page you want into a single-page PDF, then run PDF to BMP on that.
