How Pixels to Kilobytes Conversion Works
The uncompressed file size of an image depends on three factors: width, height, and color depth (bits per pixel). The formula is:
File Size (bytes) = Width × Height × (Bit Depth ÷ 8) Compression reduces this significantly. JPEG typically achieves 10:1 compression (high quality) to 20:1 (web quality). PNG uses lossless compression, typically 2:1 for photographic content.
