Scale a large image down to the exact pixel dimensions you need, with the aspect ratio kept by default so nothing looks stretched.

About this tool

Our free image resizer changes a photo to exact pixel dimensions or by percentage. It is the tool you need when a form demands a 600×600 passport photo, when a marketplace wants a specific listing size, or when you simply want to make a large image smaller for the web. Type the exact width and height you need, keep the aspect ratio locked so the image never looks stretched, or unlock it to set each dimension independently. Social-media presets make sizing for profiles and posts effortless. Unlike paid editors, GetFreeToolsAI is completely free with no daily limits and no watermark. Resizing happens entirely in your browser using the HTML canvas, so your image is never uploaded to a server and stays private on your device. It works in Chrome, Firefox, Safari, and Edge with no installation and no signup, ever.
