Frequently Asked Questions
Is my image uploaded to a server?
No. All resizing happens locally inside your browser using HTML5 Canvas. Your images never leave your device.
Does resizing reduce image quality?
Minimal quality reduction occurs when scaling down. The browser canvas uses smooth interpolation for clean results.
Does it keep the aspect ratio?
Yes, by default the aspect ratio is locked to prevent stretching. You can uncheck 'Lock Aspect Ratio' to set custom dimensions.
