Learn about this tool
You can convert BMP to PDF with up to 20 bitmap images in a file. BMP is usually created by old software, scanners, or uncompressed export modes, so even a few images can occupy a lot of space.
The total size of the selected BMP files must not exceed 256 MB. It is recommended to crop the image close to the content area before uploading. The tool maintains the aspect ratio, automatically rotates images, and does not have separate options for DPI or paper size.
Convert BMPs exported from accounting or lightweight CAD applications into PDF for sending.
Combine BMP pages from old scanners into a document that is easy to open.
Convert separate BMPs into a PDF to keep with the records instead of maintaining many bitmap files.

Frequently asked questions
The tool accepts valid BMP files based on the file signature. Very large images still must remain within a total of 256 MB. If a file is not a real BMP even if it has a .bmp extension, the system will reject it.
Not on this page. Each format tool only accepts that specific type. Convert each group separately, or use Image to PDF for JPEG, PNG, and WebP.
Images are placed on the PDF page with the original scale, but the PDF is not a byte-for-byte copy of the BMP. The size and internal compression in the PDF may differ from the source file.
Access expires after one hour and cleanup runs every five minutes. Download any results you need before they expire.
