No. Everything runs in your browser using the HTML5 Canvas API. Your image never leaves your device.
You can upload PNG, JPEG, WebP, GIF, and BMP. You can download the resized image as PNG (lossless) or JPEG (smaller file size). GIF animations are not preserved — only the first frame is resized.
Scaling down (reducing size) generally retains good quality. Scaling up (enlarging) will make the image appear softer or pixelated since pixels are interpolated. For JPEG output you can control quality with the quality slider.
