Everything you need to know about BMP to PNG conversion
BMP (Bitmap) is an image format developed by Microsoft for Windows. It stores image data without compression, resulting in perfect quality but extremely large file sizes.
No, PNG uses lossless compression, meaning it preserves every single pixel exactly as in the original BMP. The quality is identical, but the file size is significantly smaller.
PNG files are 50-80% smaller than BMP, meaning faster website loading times and better user experience. PNG is also universally supported by all web browsers, while BMP is rarely used online.
Yes, PNG fully supports transparency (alpha channel). This makes it perfect for logos, icons, and graphics that need to overlay on different backgrounds. BMP has limited transparency support.
Yes, your images are processed entirely in your web browser. We never upload your BMP files to any server, so your images remain completely private and secure.
We support BMP files up to 50MB, which is sufficient for most bitmap images.
