What PNG to BMP conversion does

Convert a PNG image to BMP directly in your browser. BMP is a widely recognized uncompressed bitmap format still expected by some older Windows software and compatibility workflows that do not read PNG.

How to convert PNG to BMP

1. Choose a PNG file.
2. Select Convert & download.
3. Save the .bmp file from your browser downloads.

Why use this conversion

BMP is the format some legacy Windows applications, print pipelines, or embedded/older tooling expect by default. Converting a PNG to BMP keeps compatibility with software that does not understand PNG.

Transparency and output quality

BMP output here is 24-bit RGB with no alpha channel. Transparent pixels from the source PNG are flattened onto a white background, the same convention used for JPG output. This tool writes an uncompressed 24-bit BMP, so the file will usually be noticeably larger than the source PNG.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: PNG (.png) only, up to 25.0 MB and 8,192 px per side.
• BMP output has no transparency support in this tool — use PNG to WebP or PNG to AVIF instead if you need to keep an alpha channel.
• Metadata is not preserved in the downloaded file.

PNG to BMP FAQ

Why convert PNG to BMP?

BMP is a widely recognized uncompressed bitmap format expected by some older Windows software, print workflows, and legacy tooling that does not read PNG.

Does BMP output keep transparency?

No. BMP output here is 24-bit RGB with no alpha channel. Transparent pixels in the source PNG are flattened onto a white background, the same convention used for JPG output.

Is BMP output compressed?

No. This tool writes an uncompressed 24-bit BMP (BITMAPINFOHEADER, BI_RGB), so the file will usually be larger than the source PNG.

Are my files uploaded?

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

What is validated before conversion?

The file must actually be a PNG — the tool checks the PNG signature bytes, not just the filename or extension, before decoding.
