Everything You Need to Know About DexImage Resize Image
Understanding Aspect Ratios in Resizing
Locking aspect ratio ensures your image width and height remain mathematically proportional, preventing distorted or stretched visual output.
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.
