About PNG to BMP
PNG to BMP converts PNG files to BMP. PNG is a lossless raster format that supports full transparency. It suits screenshots, logos and graphics with sharp edges, but photographs make large PNG files. BMP is an old, usually uncompressed Windows bitmap format, so files are very large.
The formats involved, when to use this conversion, and where it runs.

Legacy Windows software and devices that only open bitmap files.
Converted on our servers with our image processing service. The file travels over HTTPS and is deleted automatically afterwards.
Desktop, tablet, or mobile—use the same workflow on any device.
Start converting for free with no account. Paid plans raise limits; see the Pricing page.
What happens to your file from upload to download.
The file type and size are checked before anything is processed, so unsupported files are rejected straight away.
The file is uploaded over HTTPS and converted to BMP with our image processing service.
Save the result to your device. Copies on our servers are deleted automatically by a cleanup job.
Other conversions available for these formats; search above to open them.
Step-by-step instructions for this conversion.
Add your PNG file by dragging it into the upload area or choosing it from your device.
Confirm BMP as the output format and, if offered, adjust quality or size.
Start the conversion. The file is uploaded and converted on our servers while the progress bar updates.
Download the BMP file and check it before deleting the original.
Differences between the two formats that affect the result.
BMP files are uncompressed and can be many times larger than the source image. Images larger than 1,024 pixels are scaled down to fit.
BMP cannot store transparency, so transparent areas in the PNG are filled with a solid background. If you need to keep a see-through background, choose PNG or WebP instead.

You download a new BMP file; your PNG file is not changed.
This conversion runs on ToolzStack servers: your file is uploaded over HTTPS, converted, and kept only so that you can download the result. An automated cleanup job then deletes it (see the Privacy Policy for the current retention period).

BMP has no transparency, so transparent pixels are filled with white. Use PNG or WebP to keep transparency.
Make sure the file really is PNG (renaming an extension does not change the format) and that it opens correctly on your device. Password-protected, DRM-protected or corrupted files are rejected. If the file is very large, try again with a smaller one.
