Does resizing reduce image quality?
Downscaling keeps images sharp and even reduces file size. Upscaling enlarges existing pixels, so the result may look slightly soft — this is true of any resizer.
Which image formats are supported?
JPG, PNG and WebP. The output keeps the original format of your image.
Are my images uploaded to a server?
No. All processing happens locally in your browser — your images never leave your device.
