Frequently Asked Questions

What image formats are supported?

The tool supports JPEG, PNG, and WebP image formats. The output format will match your input format.

Should I maintain aspect ratio?

Yes, if you want to avoid distortion. When aspect ratio is maintained, changing width automatically adjusts height (and vice versa) to keep the image proportions. Disable it only if you need exact custom dimensions.

Will resizing reduce image quality?

Resizing down (making smaller) generally maintains good quality. Resizing up (making larger) may reduce quality as pixels are interpolated. The tool uses high-quality canvas rendering with 92% compression quality.

Is my image uploaded to a server?

No, all image processing happens in your browser using HTML5 Canvas. Your images never leave your device and are not uploaded to any server. Everything stays private.
