About BMP to PNG
BMP and PNG are both lossless formats, but BMP stores pixels uncompressed while PNG applies DEFLATE compression. That means a PNG converted from a BMP is typically much smaller without any loss in quality. PNG also handles transparency, though standard BMP files do not contain an alpha channel.
This tool converts BMP files to PNG directly in your browser. Your images never leave your device — the conversion runs locally using the Canvas API. No upload queue, no server processing, no privacy risk.
Output is pixel-perfect: full resolution, exact colors, and no compression artifacts. PNG uses lossless compression, so nothing is thrown away. Ideal for design pipelines and archival — no watermark, no account, no limit.
Perguntas Frequentes
Why convert BMP to PNG?
PNG applies lossless compression to the same pixel data, so you get a smaller file with identical quality. PNG is also more widely supported in design tools and web workflows than BMP.
What is PNG format?
PNG is a lossless image format that supports transparency. Unlike BMP, it compresses the image data, which makes files smaller without throwing away any pixels.
Will the image quality be preserved?
Yes. PNG uses lossless compression, meaning no image data is thrown away. Resolution and color accuracy are preserved exactly.
Is there a file size limit?
There is no hard limit. Since processing runs locally in your browser, the practical limit depends on your device's memory. Most BMP images convert instantly.
Do I need to sign up or pay?
No. There is no account, no watermark, no subscription, and no "upgrade for HD" trap. Every feature is free and unlimited.
Is my image data safe?
Yes. All conversions happen entirely in your browser using the Canvas API. Your images never leave your device — no uploads, no servers, no logging.
