About BMP and PNG
What is BMP?

Is my file safe?
Files are converted on our servers and immediately deleted. We never store or share your files.
What's the maximum file size?
You can convert files up to 100MB.
Why convert BMP to PNG?
BMP files are uncompressed and very large. PNG provides lossless compression that typically reduces file size by 50-80%.
Will any quality be lost?
No. PNG is lossless, so the image will be pixel-identical to the original BMP.
