Resize any image to the exact size you need without uploading it anywhere. Choose a picture from your device, then enter new width and height in pixels or scale by a percentage. With the keep aspect ratio option on, changing one dimension updates the other automatically so your image never looks stretched or squashed. This is ideal for shrinking a photo to meet an upload limit, preparing a thumbnail, or fitting an image into a layout. When you are happy, download the resized copy in one click. Because all the work happens on a canvas inside your browser, your original file is never sent to a server, which keeps your images completely private and makes the whole process fast even for large photos. The original file on your device is left untouched.
