Why resize images?
Different uses call for different dimensions: social media covers, avatars and ID photos all have fixed specs, while oversized web images slow down page loads. With a resizer you can quickly set an image to an exact width and height to meet upload rules or shrink the file.
100% local processing, private by design
Unlike many online resizers that upload your images to a server, this tool runs entirely in your browser using the Canvas API. Your images are never uploaded, stored or sent to any third party — ideal for IDs, contracts and any photo containing personal information.
Lock ratio and presets
The aspect ratio is locked by default, so changing the width updates the height automatically to avoid distortion. When you need an exact fixed size (like an ID photo or social cover), tap a built-in preset to apply it instantly, or unlock the ratio to enter width and height freely.
