Image Quality & Compression
HEIC uses 'lossy' compression (like JPG) but is much smarter at it. It can reduce file size by 50% while keeping quality high. PNG uses 'lossless' compression, meaning it keeps every single pixel perfect, but file sizes are much larger.
Transparency Support
Both formats support transparent backgrounds (alpha channels). However, HEIC transparency is not widely supported on the web yet. PNG is the gold standard for transparent logos and graphics on websites.
Compatibility
PNG opens everywhere — browsers, editors, phones, old PCs. HEIC is strictly for modern Apple/Windows systems.
