ImageResizer.com works by uploading your picture: its own page says images are uploaded over an encrypted SSL connection and deleted automatically within six hours. A browser-based resizer sets the exact width and height and scales the image on your own device, so the photo is never uploaded at all.

Open Image Cropper →ImageResizer.com is a clean, no-watermark resizer, and its own copy explains that your images are uploaded via a secure encrypted connection and deleted automatically within six hours. That is a reasonable policy, but it still means the picture travels to and briefly lives on its servers. A client-side resizer never sends the file anywhere: the browser reads the image, scales it to your target dimensions, and downloads the result locally.
Local resizing is the safer default for a screenshot with personal information, an unpublished product shot, or any photo of a person, because nothing is uploaded and there is nothing to delete afterward. You still get exact pixel dimensions with an optional locked aspect ratio, and a companion cropper handles trimming to a region, both entirely in your browser.
