What Is an Image Resizer?
An image resizer changes the width and height of an image while keeping it usable for web pages, social media, printing, or storage. This tool resizes your image directly in your browser — your photo is never uploaded to any server, so it stays completely private.

Frequently Asked Questions

Use JPEG for photos (smaller file size), PNG for images that need transparency, and WebP for the best balance of quality and file size on modern browsers.
