Most reputable converters are safe, but always check privacy policies. Browser-based tools like Squoosh are safest as files never leave your computer.

What's the difference between JPG, PNG, and WebP?

JPG: Best for photos, supports compression. PNG: Lossless, supports transparency. WebP: Modern format, 30% smaller than JPG with same quality. Use WebP for web if supported.
