Can I convert BMP to PNG?

Yes. Choose the BMP file in BMP to PNG and download the converted image. There is no quality slider because PNG encoding here is lossless.

Does this preserve BMP transparency?

Only when the browser decodes an alpha channel from the source BMP. Most BMP files have no transparency, so most outputs are fully opaque.

Are my files uploaded?

No. BMP to PNG conversion runs locally in your browser and does not upload your file to Looty Tools servers.

Why is the PNG a different size than the BMP?

PNG uses lossless compression, so file size depends on image content rather than matching the original BMP byte-for-byte.

Why did decoding fail?

Some uncommon BMP variants or corrupted files cannot be decoded by every browser. Try re-exporting the file, or use a current version of Chrome, Edge, Firefox, or Safari.

Can I convert to JPG instead?

Use BMP to JPG when you need a smaller file and do not need transparency.
