Image Resizer
Resize your images to custom or preset dimensions
Image Size Reference: Social Media & Web
Upload any image in JPG, PNG, or WebP format. The tool shows the current dimensions and file size so you know exactly what you are starting with.
Enter the width and height in pixels, or choose from preset sizes for social media platforms. Keep "maintain aspect ratio" enabled to prevent stretching.
Download the resized image as JPG or PNG. All resizing happens in your browser — your original image is never uploaded to any server.

Resizing vs Cropping
Resizing scales the entire image to new dimensions while keeping all content visible (with possible distortion if aspect ratio is not maintained). Cropping cuts part of the image to fit a target ratio without distortion. For social media images that require exact ratios like 1:1 or 4:5, cropping typically produces better results than resizing.
