BMP to PNG: cut the weight by 5× without losing quality
BMP is a legacy uncompressed Windows format: a 24 MB BMP can become a 5 MB PNG with no visible loss. The final format should match how you plan to use it. Conversion is available on the free plan within its daily usage quota. The result depends on what the BMP and PNG formats can preserve.
Universal compatibility, unlike BMP
Every browser, website, social network, and modern app opens PNG. BMP is stuck on Windows and legacy software — not natively rendered on iOS or by Instagram, for example. A quick check can prevent problems later. Choose a file, run the conversion, then check the result before downloading it.
Transparency preserved when present
Some BMPs embed an alpha channel (32-bit BMP): the PNG conversion preserves it. For graphic or web use, that transparency lets you drop the image over colored backgrounds without further cut-out work. A quick check can prevent problems later. Always check the output file before sharing it.
