FAQ
Are my images uploaded when I resize them?
No. Resizing uses the Canvas drawImage API to scale your image entirely within the browser. The original and resized versions exist only in browser memory and are discarded when you navigate away.
What output format is used?
Resized images are exported as PNG for lossless quality.
Can I keep the aspect ratio?
Yes. Enable 'Maintain Aspect Ratio' so changing width or height updates the other automatically.
