Why Convert Image Formats?

Different image formats serve different purposes. JPEG is ideal for photographs because its lossy compression achieves very small file sizes. PNG preserves every pixel and supports transparency, making it perfect for logos and graphics. WebP, developed by Google, offers superior compression for modern websites — producing files 25–35% smaller than JPEG at equivalent visual quality. Converting iPhone HEIC photos to JPEG or PNG ensures universal compatibility across all devices and software.
