BMP (Bitmap) is a raster image format developed by Microsoft. It stores pixel data with no compression, making it a lossless format that is widely supported by Windows applications. BMP files are larger than JPEG or PNG but contain full, uncompressed image data.

What DPI should I use when converting PDF to BMP?

For screen viewing, 96 DPI is sufficient. For printing, use 150 or 200 DPI for standard quality, or 300 DPI for professional print quality. Higher DPI produces sharper images but larger file sizes.

Can I convert a multi-page PDF to BMP?

Yes. Every page of your PDF is converted to a separate BMP file. You can download pages individually or use the Download All as ZIP button to get all pages in one archive.

What color depth does the BMP output use?

The converter produces 24-bit true color BMP files, which support over 16 million colors and faithfully reproduce the full color range of your original PDF pages.

24-Bit True Color BMP

Every converted page is saved as a 24-bit uncompressed BMP — the most compatible BMP format, supported natively by Windows, Paint, Photoshop, GIMP, and virtually every image editor.

DPI Resolution Control

Choose from 72, 150, 200, or 300 DPI. Screen-use exports are fast and compact at 72 DPI, while 300 DPI gives you professional-grade print resolution from your PDF pages.

100% Private — No Uploads

Your PDF never leaves your device. All conversion happens locally using PDF.js in your browser. Safe for confidential, legal, medical, and personal documents.

Download All as ZIP

Convert a multi-page PDF and download all BMP files at once with a single click. Pages are packed into a ZIP archive named after your original PDF file.

Live Preview

Every PDF page renders as a thumbnail preview before you download. Change the DPI setting and new renders update automatically, so you always know what you'll get.

Lossless BMP Output

BMP is an uncompressed format — there is zero quality degradation. Unlike JPEG, no image data is discarded. Every pixel is preserved exactly as rendered from the PDF.

When Do You Need to Convert PDF to BMP?

BMP is the preferred format for many Windows workflows and legacy applications.

🖨️ Print Production Workflows

Some professional print RIPs and prepress workflows require BMP input. Convert PDF pages to high-DPI BMP files for direct printing pipeline compatibility.

🖥️ Windows Application Integration

Legacy Windows software — including older versions of Microsoft Office, industrial HMI panels, and kiosk systems — often only accept BMP files as image input.

🎮 Game Development & Assets

Many game engines (Unity, Unreal, GameMaker) and texture tools accept BMP as a raw source format. Convert PDF artwork or diagrams for import into your asset pipeline.

🔬 Technical & Scientific Imaging

Scientific software, lab instruments, and imaging analysis tools often require uncompressed BMP files to ensure pixel-accurate data and avoid JPEG compression artifacts.

📋 Document Archiving

Archive individual PDF pages as standalone BMP image files for use in document management systems, databases, or repositories that store images rather than PDFs.

🎨 Image Editing

Open a PDF page in any image editor by first converting it to BMP. BMP opens instantly in MS Paint, Photoshop, GIMP, and Affinity Photo without any plugin required.

What is a BMP File?

Understanding the BMP format and why it remains widely used.

BMP (Bitmap Image File) is a raster graphics format developed by Microsoft and IBM. It stores raw, uncompressed pixel data — meaning every pixel's color is written directly to the file with no compression algorithm applied.

Because BMP files are uncompressed, they are lossless — there is no quality degradation whatsoever. This makes BMP ideal for situations where pixel-perfect fidelity is required, such as technical imaging, print prepress, and legacy software compatibility.

The trade-off is file size: a 300 DPI BMP of an A4 page will be significantly larger than the equivalent JPEG or PNG. For most modern web and document use cases, PNG or JPEG are preferred. But for Windows compatibility, hardware interfaces, and uncompressed pipelines, BMP remains the format of choice.

Frequently Asked Questions

Everything about converting PDF files to BMP images online for free.

How do I convert a PDF to BMP online for free?

Upload your PDF, choose your desired DPI, then click the download button on any page. Each PDF page is converted to a separate BMP file and downloaded instantly. You can also download all pages as a ZIP archive with one click.

What is a BMP file and why would I need one?

BMP (Bitmap) is an uncompressed raster image format from Microsoft. It stores raw pixel data with zero compression, making it lossless and pixel-perfect. It's used in Windows applications, legacy software, print workflows, scientific imaging tools, and any situation where compressed formats like JPEG are not acceptable.

What DPI should I use for PDF to BMP conversion?

Use 72 DPI for quick screen previews, 150 DPI for standard digital use, 200 DPI for good-quality printing, and 300 DPI for professional print-quality output. Keep in mind that BMP files are uncompressed, so 300 DPI files will be very large (often 20–60 MB per page).

Are my PDF files uploaded to a server?

No. All PDF to BMP conversion happens locally in your browser using PDF.js. Your files never leave your device — it is completely safe for confidential, legal, medical, and personal documents.

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

Yes. Every page of your PDF is converted to a separate BMP file. Download pages individually by clicking the button on each page card, or use Download All as ZIP to save every page in one archive.

Why is my BMP file so large?

BMP files are uncompressed, so every pixel is stored as raw data — typically 3 bytes per pixel for 24-bit color. A 300 DPI A4 page is 2480×3508 pixels, which equals roughly 26 million pixels × 3 bytes = ~78 MB uncompressed. If you need smaller files, consider using our PDF to PNG or PDF to JPG converters instead.
