About converting BMP to PNG

This converts BMP images to PNG entirely in your browser. BMP is an uncompressed Windows format that stores images at full quality but in very large files. PNG is a lossless format that keeps every pixel exactly and supports transparency, at the cost of larger files — ideal for graphics, screenshots and logos. Converting a BMP to PNG is the standard way to shrink a huge uncompressed bitmap without losing any quality. The conversion runs on your device using the Canvas API, so your images are never uploaded.

How it works

Your BMP image is decoded and redrawn onto an HTML canvas, then re-encoded as PNG. PNG is lossless, so no quality is thrown away in the encoding. The pixel dimensions are kept the same — only the format changes. PNG supports transparency, so transparent areas are preserved.

Good to know

The PNG is dramatically smaller than the BMP with identical pixels, since PNG compresses losslessly where BMP does not.

Privacy

Conversion happens entirely in your browser with the Canvas API. Your BMP images and the PNG result are never uploaded or stored. Re-encoding also strips any embedded metadata, such as camera info or GPS location.

Perguntas frequentes

Is this BMP to PNG converter free?

Yes — 100% free, no sign-up, no watermark, and no limits. It runs entirely in your browser.

Are my BMP images uploaded to a server?

No. Conversion runs on your device with the Canvas API, so your images never leave your browser.

What happens to transparency?

PNG supports transparency, so transparent areas are kept in the converted image.

Will the image quality change?

PNG is lossless, so the encoding itself adds no quality loss.

Does it change the image dimensions?

No. The width and height stay the same — only the file format changes. Use the Resize Image tool if you also need to change the size.

Does converting remove my photo's metadata?

Yes. Re-encoding through the canvas strips embedded metadata like camera details and GPS location — a small privacy bonus.
