DownloadAbout BMP to PDF
Combines BMP images into a PDF. The format is rare nowadays, but when you meet it, it is usually painful — BMP applies no compression at all, storing every pixel as-is, so the sizes are absurd: a 4000 × 3000 BMP is about 36 MB, while the same picture as JPG might be 2 MB.
Converting to PDF usually shrinks it dramatically, because what goes into the PDF is compressed JPEG — a 36 MB BMP often ends up a few megabytes. That is the practical use here: gathering BMPs spat out by old software, industrial equipment or scanner drivers into a single PDF you can email or archive.
Output quality is 92, which is invisible in practice. For charts or text documents there may be faint colour fringing; output at original dimensions and accept the larger file if you need it perfectly clean.
Typical BMP sources: old Windows programs, some medical and industrial devices, scanner drivers, and screenshots from early games. Those situations rarely offer another format, which is why this entry is worth keeping on its own.
Frequently asked questions
Why are BMP files so large?
They are uncompressed; every pixel is stored in full. A 4000×3000 BMP runs about 36 MB, where the same content as JPG might be 2 MB.
Will the PDF be smaller?
Yes, usually much. What goes into the PDF is compressed JPEG, so a 36 MB BMP often becomes a few megabytes.
What produces BMP files?
Old Windows programs, some medical and industrial devices, scanner drivers, and screenshots from early games. Those setups often offer no other format.
Can I convert many at once?
Yes, but BMPs are large and dozens at a time will consume a lot of memory — batch them.
