JPG is best for photos and is accepted everywhere. PNG keeps sharp edges and transparency — use it for logos, screenshots and graphics. WebP gives files 25–35% smaller than JPG at similar quality and is supported by every modern browser, which makes it the best choice for websites.

No. Images are processed with your browser's canvas — they never leave your device, so it's safe for ID photos, product shots and screenshots containing private information.
