Converting JPG to PNG stops generational loss when performing multi-pass editing, ensuring crisp lines and solid text reproduction.

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.
