Image Resizer
Change the width and height of an image. Optionally keep the aspect ratio and export as JPG, PNG or WebP.
Your files never leave your device. All processing happens in your browser.
How to use
Upload an image, enter a new width or height, choose a format, then download.
How it works
Your browser redraws the image onto a canvas at the new size. Nothing is uploaded.
