BMP to PDF
Convert uncompressed BMP bitmaps to PDF and cut the file size dramatically. Ideal for old scans and Windows-era image archives.

Über dieses Tool
BMP stores pixels with essentially no compression, which is why a single scanned page can occupy 25 MB. Files in this format usually come from older Windows software, medical or industrial imaging systems, and scanner drivers that were configured a decade ago and never revisited.
Converting to PDF applies proper image compression during embedding, and the size drop is dramatic - often 90 percent or more with no visible difference, because there was no compression to lose in the first place.
You also get one document instead of a folder of individual bitmaps, which makes the collection far easier to store, index and send.
Bedienungsanleitung
Add your BMP files
Drop in up to 100 bitmaps. Large files are expected with this format.
Arrange the pages
Drag into order if the bitmaps are pages of one document.
Set page size and compression
Choose the page dimensions and how aggressively to compress during embedding.
Convert and download
Save the PDF and compare the size to the originals.
Anwendungsfälle
Old scanner output
A folder of 20 MB bitmaps becomes a PDF of a few megabytes.
Legacy system exports
Industrial and medical software that only writes BMP, converted into something shareable.
Archiving image sets
Hundreds of loose bitmaps consolidated into indexed PDFs.
Häufig gestellte Fragen
How much smaller will the PDF be?
Typically 85 to 95 percent smaller. BMP is uncompressed, so almost all of the size is redundancy.
Does the image quality suffer?
At high quality settings the difference is not visible. Lower settings trade sharpness for size in the usual way.
Are 1-bit and 8-bit bitmaps supported?
Yes - monochrome, greyscale, palette and full-colour BMPs all convert.
Can I mix BMP with other formats?
Use Image to PDF for mixed folders. This tool is BMP-only.
