🔁 Convert BMP to PNG
About these formats
About BMP. BMP is an old, essentially uncompressed bitmap format. Files are very large for what they contain, so converting to a compressed format saves a lot of space with no visible difference.
About PNG. PNG is a lossless format with full transparency support, which makes it ideal for logos, icons, screenshots and graphics with sharp edges or flat colour. Files are larger than lossy formats because no detail is discarded.
Going from BMP (uncompressed raster) to PNG (lossless raster) keeps your picture intact while moving to a format that can also store transparency if you need it later.
When to keep the original instead. There is no quality penalty to worry about here, but it is still wise to keep the original BMP as a master copy.
