Uncompressed Output

BMP files store every pixel without any compression. This ensures zero quality loss and no artefacts — what you see is exactly what is in the file.

🖥️

Maximum Compatibility

BMP is supported by every version of Windows, legacy industrial software, older medical imaging systems and virtually every image viewer ever made.

🎨

Full Color Depth

Supports 24-bit and 32-bit color depth. Every color in your PDF page is preserved exactly in the BMP output.

🔒

100% Private

All conversion runs in your browser. Your PDF never leaves your device.

Our old industrial CNC software only accepts BMP. This tool is the only one I found that produces clean BMP from PDFs without needing desktop software.

Works well for extracting pages as BMP for legacy print workflows. Wish BMP files were smaller but that's the format's nature, not the tool's fault.

I needed BMP files for an older image processing pipeline. This produced pixel-perfect output at 300 DPI with no artefacts. Very impressed.

📖 How to Convert PDF to BMP

Upload Your PDF

Drop your PDF onto the upload area or click to browse. Any PDF type is supported — text documents, scanned pages and vector graphics all convert accurately.

Select Pages & DPI

Choose all pages, a range or just the first page. Set DPI from 72 (screen) to 600 (high-res archiving). Higher DPI = larger BMP files.

Configure Color Options

Select 24-bit or 32-bit color depth. Enable white background for transparent PDF areas to ensure clean BMP output.

Download BMP Files

Click Convert to BMP and download all files as a ZIP archive, ready for use in any legacy or modern application.

🎯 Choose a Different Output Format

❓ Frequently Asked Questions

What is a BMP file and when should I convert PDF to BMP?+

BMP (Bitmap) is an uncompressed raster image format developed by Microsoft. Every pixel is stored individually without any compression algorithm. This makes BMP files larger than JPG or PNG, but ensures absolutely no quality loss. Convert PDF to BMP when working with legacy software, industrial systems, older medical imaging tools, or any workflow that specifically requires uncompressed bitmap input.

Why are BMP files so large?+

BMP stores every pixel individually without compression. A 150 DPI A4 page as BMP is typically 5–15 MB, whereas the same page as PNG is 300–800 KB and JPG is 100–300 KB. This is a characteristic of the format — the tradeoff is zero quality loss and universal compatibility.

Is BMP better quality than PNG or JPG?+

BMP and PNG both offer lossless output, so they're equal in quality for practical purposes. JPG is lossy, so BMP and PNG are both higher quality than JPG. The key difference is that BMP uses no compression (larger files) while PNG uses lossless compression (smaller files). For quality, they're identical. For file size, PNG wins.

What DPI should I use for BMP conversion?+

Use 72 DPI for screen display (smaller files), 150 DPI for balanced quality, 300 DPI for print-quality output, and 600 DPI for high-resolution archiving. At 300 DPI, an A4 page BMP is approximately 25 MB — plan storage accordingly.

Can I convert a multi-page PDF to multiple BMP files?+

Yes. Each page becomes one BMP file. All files are zipped into a single download. Use the page range selector if you only need specific pages.

What color depth should I choose — 24-bit or 32-bit?+

24-bit BMP stores RGB color (16.7 million colors) with no transparency. 32-bit BMP adds an alpha channel for transparency. Most applications that accept BMP use 24-bit. Use 32-bit only if your downstream software explicitly requires it.

Will converting PDF to BMP lose quality?+

No. BMP is uncompressed, so the conversion process preserves all pixel data exactly. The output quality depends only on the DPI setting — higher DPI means higher resolution and more detail.

Is my PDF private when using this tool?+

Yes. All processing is done client-side in your browser. Your PDF is never uploaded to any server. Your documents are completely private.

💡 Why Use Our PDF to BMP Converter?

🖥️

Universal Legacy Compatibility

BMP is the most compatible image format in existence. Every Windows application since Windows 3.1 reads BMP. Industrial, medical, and legacy systems that reject other formats almost always accept BMP.

🎨

Zero Compression Artefacts

JPG compression creates ringing and colour banding around text and edges. BMP has none of this. For workflows that require bit-perfect accuracy, BMP is the right choice.

🔬

Required by Specialist Software

Many scientific, industrial, and medical imaging applications require BMP input. CNC software, older imaging pipelines, and certain document management systems specifically request BMP format.

🖨️

Print Workflow Compatibility

Some prepress and print software pipelines use BMP as an intermediate format. Converting PDF to BMP ensures compatibility with these systems without requiring additional software.

🔒

Complete Privacy

Your PDF is processed entirely in your browser. Nothing is uploaded. No server sees your document.

🆓

Free with No Limits

Completely free, no watermarks, no hidden page limits. Every converted BMP is clean and full-resolution.

What Is BMP and When Should You Use PDF to BMP Conversion?

BMP (Bitmap Image File) is an uncompressed raster graphics format developed by Microsoft and IBM. Unlike JPG, PNG or WebP, BMP stores every single pixel without any compression algorithm. This results in large file sizes but ensures absolute pixel fidelity.

BMP vs Other Raster Formats

Format	Compression	Quality	File Size	Compatibility
BMP	None	Perfect	Very large	Universal
PNG	Lossless	Perfect	Medium	Excellent
JPG	Lossy	Good	Small	Excellent
TIFF	Optional lossless	Perfect	Large	Professional

Industries That Commonly Require BMP

Manufacturing & CNC: CAD/CAM and CNC software packages often require BMP input for toolpath generation from image files.
Medical imaging: Older PACS (Picture Archiving and Communication Systems) use BMP as an intermediate export format.
Legacy Windows applications: Software built for Windows XP/Vista era often has hardcoded BMP support with no alternative.
Embroidery & printing machines: Industrial embroidery machines and specialty printers frequently accept only BMP input files.

Managing Large BMP File Sizes

BMP files are significantly larger than other formats. To manage size: use lower DPI (72–150) when high resolution is not required, use 24-bit rather than 32-bit color when transparency is not needed, and convert only the specific pages you need using the page range selector. For most workflows that accept BMP, you can also compress the files into a ZIP archive without any image quality loss.
