QUICK ANSWER
Is it possible to convert BMP to PDF?
Yes - BMP converts to PDF.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

The simplest route on any OS is print-to-PDF: open the .bmp and send it to your system PDF printer to get a single-page PDF in seconds. BMP stores raw uncompressed pixels, so the output PDF is typically much smaller - though the page dimensions depend on the DPI the converter applies.

Why convert BMP to PDF?

BMP is an uncompressed format, so files are large and awkward to share or print directly. Wrapping the image in a .PDF produces a fixed-layout file that any device or OS can open without special software. PDF is also the accepted format for email attachments, upload portals, and print queues.

How to convert BMP to PDF

Microsoft Print to PDF BUILT-IN

Right-click the .bmp in File Explorer, choose Print, set the printer to Microsoft Print to PDF, and save.

macOS Preview BUILT-IN

Open the .bmp in Preview, then go to File > Export as PDF and click Save.

LibreOffice Draw OPEN-SOURCE

Insert the .bmp via Insert > Image, then export with File > Export as PDF.

Command line - ImageMagick CLI

Run magick input.bmp output.pdf; add -density 300 to set output DPI or *.bmp as the input to merge multiple files into one PDF.

.BMP Windows Bitmap Image

Quality & what to watch

  • BMP is uncompressed, so the output PDF is usually much smaller - a 10 MB .bmp often becomes 1-2 MB.
  • If the .bmp has no embedded DPI metadata (common), some converters default to 72 or 96 DPI, which can make the page unexpectedly large or small.
  • 32-bit BMP files with an alpha channel will have transparency flattened to white in most PDF converters.

Frequently asked questions

Will converting BMP to PDF reduce the file size?
Usually yes - BMP stores raw pixel data with no compression, while PDF writers apply internal compression. A 10 MB .bmp can shrink to 1-2 MB as a PDF.
Can I combine multiple BMP files into one PDF?
Yes. On Windows, select all .bmp files, right-click > Print > Microsoft Print to PDF (each file becomes one page). With ImageMagick, run magick *.bmp combined.pdf to merge them.
Does the conversion lose image quality?
Print-to-PDF and Preview export preserve visual quality. ImageMagick applies JPEG compression by default inside the PDF; add -compress Lossless to avoid any quality loss.
Why does the image look tiny or huge in the PDF?
BMP files often lack embedded DPI information, so the converter falls back to a default (72 or 96 DPI) that may not match the intended print size. Set the resolution explicitly before converting.
