Frequently Asked Questions
Is my image uploaded to a server?
No. All resizing is done entirely in your browser using the Canvas API. Your images never leave your device.
What image formats are supported?
You can upload any browser-supported image format and export as JPEG, PNG, or WebP. The original format is also preserved as an option.
Can I maintain the aspect ratio?
Yes. The aspect ratio lock is enabled by default. When locked, changing width automatically adjusts height and vice versa.
