About Image Resizer
Image Resizer is a browser-based image tool for changing image dimensions without uploading files to a server. Choose a JPG, JPEG, PNG or WebP image, enter the target width and height, and resize it directly with JavaScript canvas. The maintain aspect ratio option helps prevent stretched or squeezed results by automatically adjusting the paired dimension when you change one side. This is useful for preparing images for websites, forms, social posts, thumbnails, profile pictures, product previews, blog images and lightweight design tasks. The original image preview lets you confirm the selected file, while the output preview shows the resized result before you download it. Because processing happens locally in the browser, your image stays on your device and is not stored by Toolexa. The tool is designed for quick everyday resizing rather than complex photo editing, so the controls stay clean, responsive and easy to use on desktop or mobile screens.
