BMP to PDF
Choose your BMP bitmap images, put them in order and pick a page size. They become one PDF, made on your device.

How to convert BMP to PDF
Choose your BMP or DIB files, or drop them on the box above. You can add more and move them up or down.
Pick A4 or US Letter, then select Make PDF.
Download the PDF: one page for each bitmap, in your order.
Smaller files with no loss
A raw Windows or OS/2 bitmap stores every pixel uncompressed, which makes BMP files large. Each bitmap is compressed without loss when placed in the PDF, so scans and diagrams stay pixel-sharp at a fraction of the size.
Page size and layout
A wide bitmap gets a landscape page and a tall one a portrait page, A4 (210 × 297 mm) or US Letter (8.5 × 11 in). The bitmap is scaled to fill as much of the page as it can, centred, never cropped or stretched.
JPG, PNG and HEIC images can go in the same PDF: add them to the list too.
Your bitmaps never leave your device
Your browser reads each BMP header and pixel array and makes the PDF locally. No image, file name or page is sent to us or to anyone else, and nothing is added, not even a watermark.
