Security

Client-side by default

Resize, Compress, Convert, Crop, Rotate, Watermark, and Bulk all run in your browser. Your files never touch our servers for these tools.

AI features

Remove Background and AI Thumbnail Generator send the image you choose to our AI provider over HTTPS solely to produce the result. Images are not retained after processing.

Transport

All traffic is served over HTTPS with modern TLS.

Authentication

Optional sign-in uses secure email/password with bcrypt-hashed credentials or Google OAuth. Sessions use short-lived tokens with refresh rotation.

Report a vulnerability

Email security@resizeimagesfree.com with details. We aim to respond within 72 hours.
