How to convert png to bmp file

Legacy Windows programs, device import tools, and some game pipelines require BMP files instead of PNG. Converting creates a compatible pixel copy, usually with a substantially larger file size.

PNG format

PNG (Portable Network Graphics) is a raster format using lossless compression: it reduces file size without discarding pixel data. It is widely used for screenshots, web graphics, icons, interface elements, diagrams, and images that need clean edges or transparency.

PNG supports RGB color, indexed palettes, grayscale, and alpha transparency. Browsers, screenshot utilities, design applications, office software, Adobe Photoshop, GIMP, and Paint.NET commonly create or export PNG files.

Because its compression is content-dependent, PNG is often much smaller than BMP for screenshots, text, flat-color artwork, and interface graphics. A PNG can also store 16-bit-per-channel color, which many common BMP workflows do not preserve.

BMP format

BMP (Bitmap) is a raster format closely associated with Microsoft Windows. Standard BMP files commonly store uncompressed pixel rows, making them simple for older software and hardware to decode but much larger than equivalent PNG files.

Many BMP variants exist, including palette-based, 24-bit RGB, 32-bit, compressed, and bitfield-based files. For the broadest compatibility, use a 24-bit uncompressed BMP unless the receiving software explicitly requires another variant.

A 1920 × 1080 24-bit BMP contains 6,220,800 bytes of pixel data, about 5.93 MiB, plus headers and row padding. The size of a PNG at the same dimensions varies greatly with image content.

Convert a PNG file to BMP

Upload the PNG to the converter on 101convert.com, choose BMP as the output format, start the conversion, and download the resulting .bmp file. Keep the original PNG; creating a BMP copy does not add detail or improve image quality.

On Windows, open the image in Paint and use File → Save as → BMP picture. If Paint offers a bit-depth choice, select 24-bit BMP for older applications and devices. Test a 32-bit BMP only when the target software documents support for that specific BMP variant and alpha handling.

In GIMP, open the PNG, use File → Export As, enter a name ending in .bmp, and confirm the BMP export settings. Use Image → Flatten Image before export when the target cannot process transparent pixels.

For batch work with ImageMagick, this command composites transparency onto white before writing BMP:

magick input.png -background white -alpha remove -alpha off output.bmp

In Windows Command Prompt, convert all PNG files in the current folder with:

for %f in (*.png) do magick "%f" -background white -alpha remove -alpha off "%~nf.bmp"

Transparency, color, and compatibility

PNG alpha transparency is the main conversion issue. Although some BMP files can contain an alpha byte or alpha masks, many older BMP readers ignore it, interpret it inconsistently, or display transparent areas as black. Flatten transparent areas onto the required background color before conversion for predictable output.

A normal 8-bit-per-channel PNG converted to a 24-bit BMP retains its visible RGB pixels without JPEG-style quality loss. However, indexed PNGs may be expanded to full RGB, and 16-bit PNGs may be reduced to 8 bits per color channel by common BMP exporters.

PNG color profiles and gamma metadata are not handled consistently by BMP readers. If exact color appearance matters, check the BMP in the receiving application rather than relying only on its appearance in the exporter.
