Why convert BMP to PDF instead of JPG or PNG?

PDF is the standard for document sharing and archival. If your BMP images are part of a document workflow (reports, records, scans), PDF is the appropriate format. The conversion also significantly reduces file size since BMP is uncompressed while PDF applies efficient compression.

How much smaller will the PDF be compared to BMP?

BMP files are uncompressed and can be very large. A 10 MB BMP image typically converts to a 200 KB - 1 MB PDF depending on image content. The reduction is typically 90-98% without visible quality loss.

Are all BMP variants supported?

Yes. The converter handles standard BMP formats including 1-bit, 4-bit, 8-bit indexed color, 24-bit true color, and 32-bit with alpha channel. Both top-down and bottom-up BMP orientations are handled correctly.

Can I combine multiple BMPs into one PDF?

Yes. Upload multiple BMP files and they are combined into a single PDF with one image per page.
