How it works

KadiTools decodes your BMP file in the browser, draws it onto an in-memory canvas and encodes it again as PNG. BMP files are uncompressed, so the converted file is usually many times smaller.

PNG is lossless and supports transparency, which makes it ideal for screenshots, logos, graphics and anything you'll edit again.

FAQ

Is my BMP uploaded to a server?

No. The whole conversion happens in your browser using the Canvas API; the file never leaves your device.

Will converting to PNG reduce quality?

No. PNG is lossless — every pixel of the decoded image is kept exactly.

Is there a size limit?

There's no artificial limit. Very large images (above roughly 50 megapixels) may be slow or fail on phones because of browser memory limits.
