Convert BMP to PDF
Updated Jul 2026
BMP is an old Windows image format that stores pictures with no compression, so files are large and awkward to share. To convert BMP to PDF, open the file in a converter and export it as a PDF. Doing this on your own computer means the image never has to travel to anyone else's server first.

BMP vs PDF: what actually changes
| BMP | ||
|---|---|---|
| File size | Large, stored with no compression | Much smaller, since the image is compressed inside the PDF |
| Quality | Lossless, exact pixels | Lossless, the image is preserved as-is |
| Opens everywhere | Mostly Windows, awkward on other devices | Yes, PDF readers exist on every platform |
| Multiple pages | No, one image per file | Yes, several BMPs can become one multi-page PDF |
| Easy to print or attach | No, not treated as a document | Yes, PDF is built for printing and sharing |
| Transparency | No | No |
When to convert, and when not to
Convert BMP to PDF when you need to email, print, or archive an old Windows image as a proper document, especially if you want to combine several BMPs into one file.
Keep the BMP if you still need to edit the raw pixels in an image program, since PDF is meant for viewing and printing, not pixel-level editing.
Why not just use an online converter?
Free online BMP to PDF converters ask you to upload your file to their server, convert it there, and send it back. That means a stranger's server briefly holds a copy of whatever the image shows, whether it's a scanned document, a screenshot, or something private. Converting on your own computer keeps the file right where it is the whole time.
Questions
Does converting BMP to PDF lose quality?
No. BMP stores the image with no compression, so the PDF holds the exact same pixels. Nothing is thrown away in the conversion.
Can I combine several BMP files into one PDF?
Yes. That's actually one of the main reasons people convert BMP to PDF, since BMP only ever holds one image, and a PDF can hold as many pages as you need.
Why convert an old BMP file at all?
BMP was common on older Windows machines but isn't easy to share, print, or view consistently across devices. PDF opens the same way everywhere, which makes it a better fit for sending or archiving.
Can this be done without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never has to leave your machine or touch the internet.
Will the PDF be smaller than the BMP?
Almost always. BMP files are uncompressed and can be quite large, while the same image inside a PDF is compressed, so the resulting file is typically much smaller.
