When Should You Convert Image Formats?
Convert to PNG when you need transparency. Convert to JPG for smaller photo files. Convert to WebP when optimizing images for web — WebP files are typically 25–35% smaller than JPG or PNG at the same quality.
What’s the Difference Between JPG and PNG?
JPG uses lossy compression, ideal for photographs. PNG uses lossless compression and supports transparent backgrounds, making it better for logos, icons, and graphics with sharp edges.
