Why convert BMP to PDF at all?

BMP files are uncompressed, and many email services, portals and phones handle them poorly. A PDF is compact, opens everywhere and keeps several images together as one document.

Will the images lose quality?

No. The pixels are stored with lossless compression, so the image in the PDF is identical to the bitmap — just in a file that is far easier to send.

Can I change the page order?

Yes. Use the arrows beside each file to move it up or down before converting; the list on screen is exactly the order the pages will have.

How to do it

Add your file
Add the BMP files — scans, screenshots or exports from older software that still saves uncompressed bitmaps.
Set it up the way you want
Choose whether each page matches its image or uses A4 or Letter, and set a margin if the pages are going to be printed.
Download the result
Download one PDF, usually far smaller than the BMP files, because the bitmaps are stored with lossless compression inside it.
