Convert BMP to PNG
PNG gives you the same lossless fidelity as BMP but with proper compression, so files are typically 2–5× smaller. It's the right modern replacement for BMP whenever you need pixel-perfect images.
Your files never leave your device. No upload. No sign-up.

Why convert BMP to PNG?
Software developers, retro game artists, and scanner users convert BMP to PNG to keep every pixel exact while making files reasonable to share, store, and version-control.
Frequently asked questions
- Is PNG truly lossless?
- Yes. Every pixel in the BMP is preserved exactly in the PNG — only the file is encoded more efficiently.
- Does PNG support transparency from BMP?
- Standard BMPs are opaque, so the PNG will be opaque too. If your BMP has an alpha channel, it is preserved.
- How much smaller will the PNG be?
- Usually 50–80% smaller than the BMP, depending on the image content.
