PNG to BMP

PNG to BMP Details

This page is a single-purpose converter: it rewrites PNG files as BMP. Drop a file in, run the conversion, take the download.

PNG is a lossless raster format with a real alpha channel, so repeated saves never degrade the picture. BMP stores pixels as they are, with no practical compression standing in the way.

The workflow

The order below follows the page itself, and no step asks you to sign up or confirm anything.

1. Add the PNG files you want converted by dragging them in or clicking to browse.
2. Files line up in the queue as you add them. The ceiling is 20 files, so run a second round for more.
3. The convert button rewrites the selected file as BMP; the batch button repeats that for every PNG file in the queue.
4. Type a different name in the queue field if you want one, and the file lands with that name plus the BMP extension.
5. Save the finished BMP file with the download link, then clear the queue and start the next batch.

Limits and processing behaviour

A few details that make the decision easier:

• Accepted input: PNG (png), up to 24 MB per file.
• The result is written as BMP and written with no compression applied.
• The queue carries 20 files at a time, and each file travels in its own request.
• PNG can hold transparency and BMP cannot, so transparent pixels are flattened onto white.
• BMP applies no compression, so the output file is clearly larger than the source.
• Do not count on metadata surviving: whether EXIF and ICC data travel depends on the engine handling the file, so keep anything critical elsewhere.

When to choose this tool

This conversion earns its place when an existing PNG file has to land somewhere that asks for BMP. Legacy Windows tooling, a handful of printer drivers and software that wants raw pixels still ask for BMP. Files grow several times larger than the alternatives, and in exchange nothing is discarded. PNG is a lossless raster format with a real alpha channel, so repeated saves never degrade the picture.

If the transparent background has to survive, BMP is the wrong destination; pick the converter that outputs PNG or WebP instead.

Practical notes

• Filling the queue with 20 files and hitting convert all is faster than working through them one by one.
• Renaming outputs in the queue keeps your downloads folder readable once several BMP files land there.
• BMP is written losslessly, so saving again does no damage and the file works as an archive copy.
• Open the BMP file afterwards and check edges and colour gradients, and keep the PNG source where it is.

Privacy and data handling

Processing an image means uploading it, and that upload lives only as long as the request. Once the output exists, the file is not stored and never handed to a third party. Ads may appear on the page, but no ad network can reach your upload.
