About This Image Resizer

Resize any image online for free without installing software. This browser-based tool lets you set exact pixel dimensions, resize by percentage, or fit images within a maximum size — all without uploading your files to any server.

How It Works

Upload your image and enter your target width and height in pixels. The tool uses the browser's Canvas API to resize the image client-side. You can maintain the aspect ratio automatically or set custom dimensions independently.

Common Use Cases

  • Resize images for profile pictures (Facebook, LinkedIn, Twitter)
  • Prepare images for specific platforms (1080x1080 for Instagram)
  • Reduce image dimensions before compression for even smaller files
  • Resize product images for e-commerce stores
  • Scale down high-resolution images for faster email attachments

Supported Formats

JPG, PNG, and WebP. Output is downloaded in the same format as the original.

Privacy

All resizing happens locally in your browser. Your images never leave your device and are never stored anywhere.
