How this tool works
What it does
BMP to PNG converts a BMP image to PNG in your browser.
Lossless PNG
No quality setting — PNG is lossless and can preserve transparency when the source has an alpha channel.
Result details
The result panel shows original and output format, dimensions, and file size.
Privacy & metadata
Conversion is in-browser; nothing is uploaded. Re-encoding through the browser canvas removes EXIF and other metadata.
BMP to PNG in your browser
BMP to PNG converts a BMP image to PNG entirely in your browser — the file is processed with the HTML canvas and never uploaded to a server.
PNG can preserve transparency when the source has an alpha channel; a JPG source has none to recover. PNG is lossless, so there is no quality setting.
BMP to PNG shows the original and output format, dimensions, and file size in the result panel. BMP decoding depends on your browser; a rare BMP variant that the browser cannot decode will show a clear error. Re-encoding through the browser canvas removes EXIF and other metadata.

Frequently asked questions
Are my images uploaded to a server by BMP to PNG?
No. BMP to PNG converts the image in your browser using the HTML canvas, and the file is never sent to imgtoolsbase or any server.
Does BMP to PNG preserve transparency?
Yes. PNG supports an alpha channel, so transparency present in the BMP source is preserved. PNG is also lossless, so there is no quality setting.
Why might a BMP file fail to convert to PNG?
Browser BMP decoding varies, so a rare or unusual BMP variant may not decode. BMP to PNG relies on the browser to read the BMP, and shows a clear error if it cannot.
Does BMP to PNG change image quality or metadata?
Converting BMP to PNG is lossless (no compression quality loss), but re-encodes through the canvas, which removes EXIF and other metadata.
