About This Image Resizer
Resize images online for free without losing quality. Enter your target width and height, optionally lock the aspect ratio to avoid distortion, and download the resized image instantly.
This tool uses the HTML5 Canvas API to resize images entirely within your browser. No files are sent to any server. It supports JPEG, PNG, WEBP, and GIF images.
Common use cases include resizing images for social media profiles, blog posts, email attachments, e-commerce product listings, and mobile app assets.
Tip: Enable the aspect ratio lock to automatically calculate the corresponding dimension when you type only one value. This prevents unintentional stretching or squishing of your images.
