BMP to PDF Converter

Converting BMP images to PDF wraps uncompressed bitmap files in a portable, compact document format. BMP files are large because they store every pixel without compression, making them impractical for sharing or archiving. A PDF with embedded image compression can reduce the file size by 80–95% while maintaining visual quality, and it provides a professional single-file format for printing or distribution. SublimePDF embeds BMP images into the PDF with configurable compression, page sizing, and layout options — turning raw bitmaps into polished documents.

How to Convert BMP to PDF Online

1

Upload your BMP images

Drag and drop one or more .bmp files. BMP files are large (a 1920×1080 24-bit BMP is ~6 MB), so uploads may take a moment for high-resolution images.

2

Arrange pages and set layout

Reorder images, choose page size (fit to image, A4, Letter), set margins, and select orientation. Each BMP becomes one PDF page, or place multiple images per page in a grid layout.

3

Choose compression settings

Select lossless (Flate/ZIP) compression for pixel-perfect quality, or lossy (JPEG) compression for maximum size reduction. A 6 MB BMP typically compresses to 200 KB–1 MB in the PDF.

4

Download your PDF

The multi-page PDF is ready for sharing, printing, or archiving. The massive file size reduction makes it far more practical than storing raw BMP files.

BMP to PDF Conversion FAQ

How much smaller will the PDF be compared to the original BMP?
Typically 80–95% smaller. A 6 MB BMP page becomes 200 KB–1 MB in the PDF depending on content complexity and compression choice.
Does lossless compression maintain exact pixel data?
Yes. Flate (ZIP) compression in PDF is mathematically lossless — every pixel is preserved exactly. Choose this for medical imaging, technical diagrams, or archival use.
Are 32-bit BMP files with alpha channels supported?
Yes. 32-bit RGBA BMP files are supported. The alpha channel can be preserved as transparency in the PDF or flattened against a white background.
Can I combine multiple BMP files into one PDF?
Yes. Upload multiple BMP files and each becomes a page in the output PDF. You can reorder pages before generating the final document.
What's the maximum BMP resolution supported?
There's no hard pixel limit, but very large BMPs (e.g., 10,000×10,000 pixels) may take longer to process in-browser. Most standard BMP files convert quickly.
