Resize images without desktop software

The image resizer scales JPG, PNG, and WEBP to exact pixel dimensions or percentage — useful for social crops, thumbnail grids, and CMS upload limits.

Best practices

Downscale for web; upscaling cannot add real detail
Keep aspect ratio locked to avoid stretched logos
Export PNG when you need transparency after background removal
