About Image Resizer

This image resizer lets you change the dimensions of any image by entering exact pixel values or scaling by percentage. Lock the aspect ratio to prevent distortion, or unlock it for custom proportions. Choose your output format (PNG, JPG, or WebP) and quality level. The tool uses HTML5 Canvas with high-quality image smoothing for crisp results at any size. All processing happens in your browser.
