Frequently Asked Questions

Is BMP to PNG conversion lossless?
Yes, 100% lossless. PNG preserves every single pixel exactly as it appears in the BMP file. The file simply gets smaller thanks to PNG's DEFLATE compression algorithm, with zero quality loss.
How much smaller will the PNG be?
PNG files are typically 60-85% smaller than BMP. The exact savings depend on image content — simple graphics compress more (up to 95% savings) while complex photos compress less (around 50-60% savings).
Should I convert to PNG or JPG?
Choose PNG for screenshots, graphics, logos, or images with text — anywhere you need pixel-perfect quality. Choose JPG for photographs where smaller file size matters more than perfect accuracy. PNG files are larger than JPG but have zero quality loss.
