Convert BMP to PNG Online
Runs 100% in your browser — your files never leave your device.
BMP carries every pixel uncompressed, which makes it faithful but heavy. PNG keeps the same lossless fidelity at a fraction of the size, with broad support everywhere. Convert locally in your browser — the pixels are never re-compressed with loss.
How it works

- 2

The bitmap is decoded and re-encoded as a lossless PNG locally.
