Inspect PNG properties, check color depth, analyze transparency, and get optimization recommendations for your images.
A score from 0-100 based on file size, dimensions, color efficiency, and compression optimization.
PNG supports grayscale, RGB, RGBA (with alpha), and indexed color modes. Each affects file size differently.
Indicates how much the file size could potentially be reduced through compression and format optimization.
Use indexed color (PNG-8) for images with fewer than 256 colors to significantly reduce file size.
Only use RGBA if you need transparency. RGB without alpha is smaller and renders faster.
Remove unnecessary metadata chunks like text comments and timestamps to reduce file size.
Interlacing increases file size by 25-40%. Only use it if progressive loading is essential.
Pro tip: After analyzing, use our PNG Compressor to automatically apply these optimizations.
The quality score (0-100) evaluates your PNG based on file size efficiency, optimal color type usage, metadata presence, and compression. Higher scores indicate better-optimized files for web use.
Bit depth determines the number of colors available. 8-bit supports 256 colors (indexed), while 24-bit (RGB) supports 16.7 million colors, and 32-bit (RGBA) adds alpha transparency.
Large PNG files often result from using true color (RGB/RGBA) when indexed color would suffice, uncompressed exports from design software, embedded metadata, or interlacing. Our analyzer identifies which factors contribute to size.
