About Resize Image Online
Resize an image to the dimensions required by your website, presentation, blog or social media post. Upload a JPG, PNG or WebP file, enter your preferred width and height in pixels, and process it in your browser. Keep the aspect-ratio option enabled to scale the image proportionally and avoid stretched faces, text or logos. If you need a different shape, crop the image instead of forcing it into mismatched dimensions. Enlarging a small image cannot recreate detail that was not present in the original, so always inspect the output for softness or blur. The workspace shows your new dimensions before you download the result. For repeated layouts such as social stories or thumbnails, the Social Media Image Resizer provides commonly used presets. Your image pixels stay on your device during processing.
