BMP to PNG converts raw Windows bitmap images into PNG — a lossless but compressed format. Because BMP stores pixels uncompressed, files are huge; PNG keeps the exact same quality while compressing losslessly, so you get a pixel-identical image at a far smaller size.
This is the right conversion when fidelity matters: screenshots, graphics, line art, and anything with sharp text or transparency come through perfectly, unlike a lossy JPG. The only trade-off versus JPG is file size — PNG is larger than JPG for photographs, but still dramatically smaller than the original BMP.
Everything runs in your browser, so your images are never uploaded, with no watermark or limit, and the PNG opens on essentially any device or app.
Use this tool when you need lossless quality or transparency; when you'd rather have the smallest possible photo file, the BMP to JPG converter is the better fit.
Use PNG for screenshots, graphics, and anything with sharp text — it stays crisp and lossless
Switch to BMP to JPG if you only need a small photo file and don't need lossless quality
PNG keeps transparency if the source has it, unlike a JPG conversion
