BMP to PDF with lossless compression
-
Usually smaller than the BMP
Most BMP files store every pixel uncompressed. The PDF keeps the same pixels with lossless compression, so the file usually shrinks.
-
Pixel for pixel
Nothing is smoothed or re-encoded with loss: colors and hard edges come through exactly as in the bitmap.
-
Read by your browser
Your browser decodes each BMP, and the pixels it draws are what goes into the PDF.
-
One page per bitmap
Every bitmap is placed on a page sized for that file alone, so a small icon and a full-screen capture in the same batch each keep their own shape.
-
Named after the first file
The download takes the name of the first bitmap in your list, with the site's name added, whatever the size of the batch.
-
One failure stops the batch
A single BMP that will not open stops the whole conversion with an error instead of being skipped, so the batch either finishes together or not at all.
Bitmap to PDF: where BMP files come from
BMP is the Windows bitmap format. Paint can save it, and older scanning and screen capture software often did, so BMP files turn up in archives, shared drives and attachments from older systems.
As a PDF, the same image opens in any PDF viewer, sits on a paper size of your choice and can join your other documents in one file.
Because a BMP carries no compression to undo, the conversion has no quality decision to make: the pixels your browser reads from the file are the pixels the PDF stores, and the only thing left to choose is the page they sit on.
Whatever the source, converting a bitmap to PDF works the same way here: one page per file, at full pixel size.
When to convert a bitmap to PDF
-
Old screen captures
Screenshots saved by older Windows tools as BMP become a document that opens the same way on any computer.
-
Scanner output set to bitmap
Some office scanners default to BMP. Turning the pages into one PDF makes them easier to file and send.
-
Technical drawings from legacy CAD tools
Exports from older engineering software are often BMP; a PDF keeps the exact pixels without needing that software to view them.
-
Clearing out an old backup
A folder of uncompressed BMP files becomes a smaller set of PDFs, one per bitmap or several combined.
How to convert BMP to PDF
-
Add the bitmaps
Drop your .bmp files in; a thumbnail appears for each one.
-
Arrange them
Drag the thumbnails to set the page order, or take one out with its close button.
-
Pick the page
A4, Letter and Legal scale each bitmap to fit the sheet; Auto (Match Image) sizes the page to the bitmap itself.
-
Convert and download
Click Convert to PDF and save the result.

In everyday use, yes: BMP is the Windows bitmap format, and those images carry the .bmp extension. That is the file type this page takes.
No, the pixels-per-inch value is ignored. With Auto (Match Image), each pixel becomes one point, 1/72 inch. For a scanned page, pick A4 or Letter so it comes out at paper size.
Rare BMP variants, and damaged files, fail to load in the browser, and the conversion stops with an error. Open the image in Paint, save it again as a 24-bit bitmap and try once more.
Yes. Convert it here, then join the two files with Merge PDF.
BMP usually stores every pixel with no compression, unlike JPG or PNG, so the file is often far larger for the same picture. The PDF that comes out of it is typically smaller than the BMP itself.
Yes. Each BMP is placed on its own page, sized for that file, so a small icon and a full-screen capture can sit one after another without either being distorted.
One. Every bitmap you add becomes a page in the same file, in the order shown by the thumbnails, so a batch always comes out as a single PDF.
No. Your browser expands it to full color pixels the same way it does any bitmap, so the black-and-white result looks the same but is no longer stored in that compact 1-bit form.
