Free Online Image Resizer

Whether you need a profile picture at exactly 400×400 pixels, a banner scaled down to 50% for faster loading, or a product photo resized to fit an online marketplace's requirements, LovePDFImg's Resize Image tool handles it in seconds. Enter the exact width and height you need, or use percentage mode to scale proportionally, and the aspect ratio lock keeps your image from looking stretched or squashed.

The resize is performed using the Canvas API directly in your browser: your image is drawn onto a canvas at the new dimensions and exported back to its original format (JPG, PNG, or WebP). Because the whole process runs on your device, there's no waiting for an upload or download from a server, and your image is never seen by anyone else.
