Convert BMP images to PDF
Combine BMP bitmaps into a single PDF in your browser. Reorder, choose page size, no upload required.
Files are processed entirely in your browser. Nothing is uploaded to any server.
About this tool
BMP — Bitmap — is one of the oldest image formats in use. It stores pixel data without compression, which means every pixel is recorded exactly, with no quality loss whatsoever. That makes it common in certain technical and legacy workflows: screenshots from older Windows utilities, exports from scientific instruments, and output from older industrial imaging software often arrive as BMP files.
BMP to PDF converts these uncompressed bitmaps into a PDF document that any modern reader can open. Because BMP files are large by nature, they are converted to JPEG inside the PDF to produce a practical file size, while maintaining visually equivalent quality. Arrange multiple BMPs into the order you need, choose your page dimensions, and download.
Mixing BMP with other formats in the same PDF is supported — add JPG, PNG, or WebP files alongside your BMPs and they will all be combined in sequence. No upload is required; the entire conversion happens in your browser.
