How It Works

This free online image resizer processes your photos entirely in your browser — no upload is ever sent to a server.

  1. 1. Choose your image

    Click the upload area or drag and drop any JPG, PNG, WebP, or GIF from your device. It loads instantly into the tool — nothing leaves your computer.

  2. 2. Set the size you need

    Type in the width and height you want in pixels, or choose a percentage to scale up or down. Turn on aspect-ratio lock to avoid stretching — the other dimension adjusts automatically.

  3. 3. Resize in your browser

    Hit Resize and your browser redraws the image at the new dimensions — no waiting, no upload progress bar, just an instant result.

  4. 4. Download your resized image

    Click Download and the file saves directly to your device. Choose JPG, PNG, or WebP as the output format before saving.
