Which Image Format Should You Choose?

🌐 WebP (Recommended)

Developed by Google, WebP provides 25% to 35% better compression than standard JPG while fully supporting alpha channel transparency. Ideal for modern websites and blogs.

🎨 PNG (Portable Network Graphics)

Lossless compression standard with full transparent background support. Best for logos, vector graphics, product badges, and icons.

📸 JPG / JPEG

Universal compatibility across every device, email client, print shop, and operating system. Best for high-resolution photography without transparency.
