PNG to BMP Converter

About PNG to BMP

Writes a PNG out as a genuine Windows bitmap: a 24-bit, uncompressed BMP assembled pixel by pixel in your browser. BMP is the old, mostly uncompressed Windows format that some legacy software, embedded displays and classroom exercises still expect, which is the usual reason to want this conversion.

How to use it

1. Drop your PNG on the upload area, or click to choose it from your device.
2. Look at the source preview to confirm you picked the right image.
3. Click Convert to BMP. There is no quality slider because BMP is not a lossy format.
4. Review the Output preview and press Download BMP to save the result.

When to use it

• Feeding an image to an older program or microcontroller toolchain whose loader only lists .bmp.
• Preparing a picture for a school assignment that specifies a bitmap file.
• Producing a plain, uncompressed raster for a script that reads raw pixels.

Questions about PNG to BMP

Why are BMP files so large?

A standard 24-bit BMP stores three bytes per pixel with no compression, so a 1920×1080 image is about 6.2 MB regardless of content. The same picture as PNG is usually a small fraction of that.

Does BMP keep transparency?

Classic 24-bit BMP has no alpha channel, so every transparent or semi-transparent pixel is blended onto white when the file is written. If you need to keep see-through areas, stay with PNG or use ICO instead.

Is the downloaded file a true BMP?

Yes. The tool writes the file itself, because a browser canvas silently returns PNG when asked for BMP. The output has the standard 14-byte file header and 40-byte info header, 24 bits per pixel, no compression, rows stored bottom-up and padded to a multiple of four bytes.

Can I set the bit depth or color count?

No. The tool always writes 24-bit color with no compression or palette, and it offers only the single Convert to BMP action.
