About this conversion
BMP files are uncompressed and often unnecessarily large. Converting to PNG applies lossless compression, typically shrinking the file substantially with zero quality loss.
Frequently asked questions
Will I lose any quality?
No -- PNG compression is lossless, so every pixel is preserved exactly.
How much smaller will the file be?
Often dramatically smaller, especially for images with flat colors or repeated patterns -- BMP’s lack of compression makes it very inefficient by comparison.
Is this safe for old scanned documents or screenshots saved as BMP?
Yes, this is a common and ideal use case for this exact conversion.
