자주 묻는 질문
Are my images uploaded to a server?
No. All image processing happens locally in your browser using canvas and WebGL APIs. Your images never leave your device.
What image formats are supported?
We support JPEG, PNG, WebP, ICO, and BMP formats depending on the tool. See the tool description for specifics.
Is there a file size limit?
Images up to 20MB are typically supported. Larger files may cause performance issues on some devices.
