FAQ
Downscaling preserves quality. Upscaling may result in some quality loss since new pixels are interpolated from existing ones. We recommend downscaling rather than upscaling for best results.
We preserve the original format of your image. If you upload PNG, you get PNG. If you upload JPEG, you get JPEG, and so on.
Absolutely not! All resizing operations happen locally in your browser via Canvas API. Your images never leave your device.
