Everything You Need to Know About DexImage PNG to JPG

Handling Transparency During PNG to JPG Conversion

Since JPG does not support alpha channels, transparent pixels must be blended into a background color. Our converter allows custom hex choices to seamlessly match your destination website background.

Why Browser-Based Client Processing Protects Privacy & Security

Traditional image optimization websites upload your private photos, biometric passport scans, and corporate documents to remote third-party cloud servers. This exposes confidential information to server logs, data leaks, and unauthorized archiving. DexImage runs entirely in your local browser using HTML5 Canvas and JavaScript engines. Your files never cross the network, guaranteeing 100% privacy, GDPR compliance, and zero server upload delays.
