About this tool
izimg upscales JPG and PNG images to high resolution in your browser for free. The tool runs fast and fully offline on your device, so your photos are never uploaded. No sign-up, no watermark, and you can upscale multiple files in a batch.
How it works
Drop your JPG or PNG files on the page. izimg enlarges them to a higher resolution right on your device. Then download the upscaled versions — nothing is sent to a server.
