About BMP To PDF
Converts BMP bitmap images into a PDF. BMP is uncompressed, so the source files are large and the tool re-encodes them on embedding rather than carrying the raw pixel data into the document.
Even very large BMP files are handled entirely in memory in your browser — nothing is uploaded, which also means no waiting on a slow upload for a 25 MB source.
How to use BMP To PDF
- Add your BMP files. They may be noticeably slower to load than other formats because of their size.
- Set page size and image placement.
- Convert.
- Download the document.
On a production
BMP turns up from older Windows equipment, industrial scanners and some measurement instruments — the kind of hardware that outlives several generations of software. Turning that output into a PDF makes it archivable alongside everything else.
Frequently asked questions
- Why are my BMP files so large?
- BMP stores every pixel uncompressed — three bytes per pixel with no encoding at all. A photograph that would be 2 MB as a JPG can be 25 MB as a BMP. The PDF will be far smaller than the sources.
- Is any quality lost?
- The pixels are exact going in. They are re-encoded for embedding, which is where any loss would occur; for line art and screenshots choose a lossless path, and for photographs the difference is imperceptible.
- Should I still be using BMP?
- Only if something in the chain requires it. PNG is lossless like BMP but a fraction of the size, and is supported everywhere BMP is. Convert once and work in PNG thereafter.
