When Should You Convert Image Formats?
Different formats serve different purposes. Convert to PNG when you need transparency. Convert to JPG for smaller photo files. Convert to WebP when optimizing images for web pages — WebP files are typically 25–35% smaller than JPG or PNG at the same quality.
What’s the Difference Between JPG and PNG?
JPG (or JPEG) uses lossy compression, making it ideal for photographs where small quality trade-offs are acceptable. PNG uses lossless compression and supports transparent backgrounds, making it better for logos, icons, and graphics with text or sharp edges.
What Is WebP and Why Use It?
WebP is a modern image format developed by Google specifically for the web. It offers significantly smaller file sizes than JPG or PNG at comparable visual quality, which means faster page load times. Most modern browsers support WebP fully.
Will Converting Reduce My Image Quality?
Converting from PNG to JPG may reduce quality slightly due to JPG’s lossy compression. Converting from JPG to PNG will not improve quality — it will just increase file size. For best results, always keep your original high-quality source and convert only for the intended use.
