BMP to PDF
Turn BMP bitmaps into one compact PDF. Every pixel stays the same, and the file usually ends up much smaller than the originals.

Converting BMP to PDF
BMP files come from older Windows programs, Paint, technical software, measuring devices and some scanners. They tend to be huge, because the picture is stored without compression. Converting BMP to PDF packs the bitmaps into one compact document that is easy to send, opens on any device and prints in a fixed order.
How to convert BMP to PDF
-
1
Choose BMP files
Click Choose images or drag .bmp files onto the page. Bitmaps from very old programs work too.
-
2
Arrange them
Each bitmap becomes one page. Set the order with the arrows and remove the files you do not need.
-
3
Choose the page size
Match image keeps each bitmap at its natural size, ideal for screenshots and diagrams. A4 or US Letter with margins suits printing.

Download the PDF
Click Convert BMP to PDF. The page count and image dimensions are checked before the download.
Why the PDF is usually smaller than the BMP
A typical BMP stores every pixel without compression, so a single screenshot can take several megabytes. In the PDF the image is stored with lossless compression: every pixel and every colour stays exactly the same, but the file often shrinks to a fraction of the original. The tool reads 1, 4, 8, 16, 24 and 32-bit bitmaps, including files with RLE compression.
Old screenshots, drawings and device output
Many archives still hold BMP screenshots, drawings from Paint or graphs exported by laboratory and machine software. Putting them into one PDF makes them easier to share and keeps them in a fixed order, with each image on its own page.
With Match image, each page follows the dimensions of its bitmap, so a diagram looks the same as on the original screen. For a report that will be printed, choose A4 or US Letter: wide images get a landscape page and nothing is cropped.
Quality, transparency and text
Because the conversion is lossless, there is no blur and no colour shift, not even with the limited palettes of old 4-bit or 8-bit images. If a 32-bit BMP contains transparency, it is kept, but PDF viewers show the page on white, so transparent areas look white.
Labels and numbers inside a bitmap remain part of the image, so they cannot be searched or copied in the PDF. To combine BMP files with photos or scans in other formats, use Images to PDF.
