Why Resize an Image?

Resizing an image can help you prepare images for websites, social media, documents, email attachments, profile pictures, and other online uses. Smaller dimensions can also make an image easier to display on different devices.

For reducing the actual file size rather than changing dimensions, use the Image Compressor. If you need a modern web format, you can also use the Image to WebP Converter.

Resize JPG, PNG and WebP Images

This free image resizer supports JPG, PNG, and WebP. You can choose custom dimensions and resize the image without installing additional software.

Image Dimensions and Aspect Ratio

Image dimensions are normally measured in pixels. For example, an image with dimensions of 1200 × 800 pixels has a width of 1200 pixels and a height of 800 pixels.

Keeping the aspect ratio enabled helps prevent the image from becoming stretched or distorted when you change its dimensions.

Image Resizing and Web Performance

Choosing appropriate image dimensions is useful when preparing images for websites. For more information about modern web image formats and image optimization, see the Google web.dev guide to images.

You can also learn more about the image formats supported on the web from MDN Web Docs.

Is This Image Resizer Private?

Yes. This tool performs image resizing locally in your browser. The selected image does not need to be uploaded to a remote server for the resizing process.
