Frequently Asked Questions

Why should I convert BMP to PNG?
PNG delivers the same lossless quality as BMP but with efficient compression, shrinking files by 60-80%. It also supports transparency and is standard for modern web design, unlike outdated BMPs.
How much smaller will my files get?
PNG typically reduces BMP sizes by 60-80% via lossless compression. A 25MB BMP from a Chicago photoshoot could easily become a 5-10MB PNG with identical pixel quality.
Will converting BMP to PNG reduce quality?
Not at all. Since both are lossless, every single pixel is preserved perfectly. PNG simply uses smarter compression to store the data in less space.
Is PNG always better than BMP?
For almost all scenarios, yes. PNG offers the same quality, transparency, web compatibility, and smaller files. You only need BMP if a specific legacy Windows app requires it.
Are my images safe and private?
Absolutely safe. All conversion happens locally in your browser. Your images are never uploaded to our servers or stored anywhere.
