Converted Images
BMP files store images without any compression, resulting in unnecessarily large files. Converting BMP to PNG applies lossless compression — reducing file size by 50-80% without losing a single pixel of quality. Unlike JPG conversion which introduces lossy compression artifacts, PNG preserves your image exactly as it is, just in a much smaller file.
Why PNG Instead of JPG?
Choose BMP to PNG conversion when you need perfect quality preservation. PNG uses lossless compression, meaning the decompressed image is pixel-identical to the original BMP. This is essential for screenshots with text, technical diagrams, UI mockups, logos, and any image where sharp edges and precise colors matter.
PNG also supports transparency, which BMP does not. While converting a standard BMP will not add transparency, the PNG format gives you the option to add transparency later in an image editor — something that would not be possible if you converted to JPG instead.
For archival purposes, PNG is the preferred format. It provides meaningful compression over raw BMP while guaranteeing zero quality loss, making it ideal for long-term storage of screenshots, scanned documents, and reference images that may need to be accessed and used years from now.
When BMP to JPG is Better
If your BMP is a photograph and you prioritize small file size over perfect quality, JPG will produce smaller files than PNG. For photos, the lossy compression of JPG is nearly imperceptible while delivering significantly better compression ratios. Use our BMP to JPG converter for that use case.
How to Convert BMP to PNG
