Why Merge BMP to PDF?

BMP (Bitmap) is Microsoft's uncompressed image format — common in Windows screenshots, legacy applications, and industrial imaging. BMP files are very large (a 1920×1080 image is ~6 MB), making them impractical to share individually. Merging BMP files to PDF compresses them into a single, compact document.

Each BMP file becomes one page in the combined PDF, with significant file size reduction since PDF compresses the raw bitmap data.

BMP to PDF Use Cases

Frequently Asked Questions

Will the PDF be much smaller than the BMP files?

Yes. BMP is uncompressed, so the PDF will be significantly smaller. "Screen" compression gives the smallest output.

Can I control PDF quality?

Yes. Under "Image Compression," set "Image Quality (%)" for embedded images. Under "Compression Type," choose Screen (smallest), Ebook, Default, Prepress, or Printer (highest quality).

Can I create individual PDFs instead of one combined file?

Yes. Under "Combine?," select "Individual PDFs" to create one PDF per BMP file.

Can I set page orientation?

Yes. Under "Page layout," choose "Portrait" or "Landscape."

Can I remove transparency?

Yes. Under "Image Transparency," choose "Removed" to replace transparent areas with a white background.
