FAQ
How do I resize an image without distorting it?
Enable the keep-aspect-ratio option: when you change the width, the height adjusts automatically to preserve the correct proportions.
Does resizing reduce image quality?
Downscaling keeps good sharpness; enlarging beyond the original resolution can look blurry because pixels are interpolated.
Are my images uploaded to a server?
No, everything happens locally in your browser. No image is uploaded and your files never leave your device.
Which image formats can I resize?
Common formats like JPG, PNG and WebP are supported, and you download the result in one click.
