BMP (Bitmap) is the legacy Windows image format — every pixel stored uncompressed, which means a screenshot of a typical desktop can easily run 5-10 MB. That's painful to email, painful to upload, and painful to store. PDF compresses the embedded image (using JPEG-style lossy or PNG-style lossless inside the PDF) and produces a file an order of magnitude smaller — without changing what you see on screen.
PDFly decodes the BMP using your browser's native image engine (BMP support has been universal in browsers for over a decade) and embeds the result into a PDF page with PDF's built-in compression. Everything runs locally — no server upload.

Step 4 — Download the PDF
When the conversion finishes, the result panel shows your new PDF with file name and size. Click "Download" to save it locally — your BMP image is now wrapped into a universally-readable document.
