Image Resizer

A free browser-based image tool that resize images to exact dimensions with aspect ratio lock. Process your photos and graphics directly in your browser without uploading to any server. Changing the pixel dimensions of a photo is one of the most common editing tasks, yet many people still open a full image editor just to do it. This resizer adjusts width and height in the browser, applying high-quality interpolation without any software install. Enter exact pixel dimensions or scale by percentage, with an optional aspect-ratio lock that prevents accidental distortion. Common preset sizes for social media, banners, and thumbnails speed up the workflow. Type the target width or height in pixels or as a percentage, and the other dimension updates automatically when the aspect-ratio lock is on. Choose a resampling filter for sharp or smooth results, then download the resized image immediately. Pixel resampling is carried out by your browser's canvas drawing routines, so the original photo and its resized copy both stay in local memory. No image data leaves your device at any point.
