About PNG Compressor
Portable Network Graphics (PNG) is the standard format for logos, illustrations, and user interface screenshots requiring transparent backgrounds. However, raw PNG files can be massive due to lossless bitmap storage. ConvertSheet's PNG Compressor selectively optimizes color palettes and entropy filters, drastically shrinking file sizes while keeping alpha transparency perfectly intact.

Frequently Asked Questions: PNG Compressor
Answers to common questions regarding inputs, calculations, and mathematical methodology.
Will my transparent backgrounds be preserved?
Yes. Our PNG compression engine fully preserves 8-bit and 1-bit alpha transparency channels.
Why are PNG files usually larger than JPEGs?
PNG is a lossless format designed for crisp line art and text, whereas JPEG is lossy and designed for photographs. Our tool optimizes PNG compression to bridge this size gap.
Is this compression safe for brand logos and icons?
Absolutely. High-contrast edges, fine typography, and vector-rendered graphics retain crisp definition.
