How Resize Image keeps your data private
Resizing happens on the HTML Canvas API, which runs on your GPU or CPU entirely inside the browser tab. Screenshots containing internal dashboards, private chats, or NDA-protected designs are never transmitted anywhere — you can resize confidential material even from a hotel or airport network without exposure.

About Resize Image
Resizing images is one of the most frequent tasks for web developers, marketers, and everyday users. Xevon Tools' Resize Image tool lets you change the dimensions of JPG, PNG, or WebP files directly in your browser without uploading anything to a server. Enter a target width or height in pixels and the tool calculates the other dimension proportionally when aspect ratio is locked. You can also unlock the ratio for non-proportional resizing when a specific dimension is required, such as platform-mandated profile picture sizes. The Canvas-based scaler produces smooth results for both enlargements and reductions, and the output is encoded at high quality to minimize any artifacts. Because everything runs on your device, even sensitive or private images stay completely local. Whether you are preparing thumbnails for a store, downscaling screenshots for a presentation, or fitting images into a CMS template, this tool delivers the right dimensions in seconds.
