WebP vs JPEG vs PNG: Which Format Should You Choose?
WebP (Best for Modern Websites & Apps)
Google's modern web format providing up to 34% smaller file sizes than JPEG while supporting transparency. Universally supported by all modern browsers.
JPEG (Universal Standard for Photography)
The time-tested standard for rich photographic imagery. Excellent compatibility with legacy software and print media.
PNG (Best for Lossless Graphics & Icons)
Lossless compression that preserves razor-sharp edges, text, and transparent alpha channels without compression artifacts.
Frequently Asked Questions
Why is WebP better than JPEG and PNG for websites?
WebP uses predictive coding and advanced entropy algorithms to deliver dramatically smaller file sizes with comparable visual fidelity. Smaller image sizes directly reduce Largest Contentful Paint (LCP) times and save bandwidth.
How does the aspect ratio lock work?
When the aspect ratio lock is enabled, changing the width automatically recalculates the height proportionally based on the active crop area, preventing any unwanted stretching or image distortion.
Is there any limit on how many images I can process?
None! Because processing happens in your browser's local memory via Canvas and hardware acceleration, you can crop, resize, and convert unlimited photos with zero fees.
Can Cloudizero host and optimize my media library automatically?
