Convert BMP images to PDF in your browser. Each image becomes a page, and nothing is uploaded — the file is built on your device. Add several images to combine them into one PDF.
100% private — files are converted in your browser and never uploaded.
Drop one or more images — they stay on your device.
Each image becomes a page, in order.
Save the finished PDF.
BMP stores every pixel uncompressed, which is why a modest screenshot can be 5–10 MB. The converter decodes the bitmap in your browser and re-encodes it as lossless PNG inside the PDF, so the image is identical but the PDF is typically 5 to 20 times smaller than the BMP.
Each BMP becomes one page at its pixel dimensions, in the order you added the files.
BMP is what older Windows tools, some scanners and screen-capture utilities still produce. Converting to PDF makes the file emailable and viewable on a phone, and lets you combine several captures into one document.
If the BMP is a photograph and size matters, converting to JPG first (BMP to JPG) and then to PDF gives a much smaller file at no visible cost.
Yes. Add several images and they're merged into a single PDF, one image per page.
No. The conversion runs entirely in your browser using JavaScript — your file never leaves your device, so it's safe even for sensitive documents.
Yes — completely free, no signup, no watermark, and no daily limits.
BMP has no compression at all. PNG inside the PDF compresses the same pixels losslessly, so nothing is lost — the BMP was simply storing them inefficiently.
Anything your browser can display works, which covers the common 24-bit and 32-bit variants. Very unusual BMP encodings may fail to decode.
