Resize an image to fit a website, document, presentation, or social post. Set the output width and height in pixels, and use the aspect-ratio option to keep the original proportions. The result is exported from your browser as a new image.

Good to know
- The current maximum width and height are 10,000 pixels each, subject to browser memory limits.
- The tool exports a new image and leaves the source file unchanged.
- Resizing may add pixels when enlarging an image, but it cannot create genuine detail that was not in the original.
Frequently asked questions
What does aspect ratio mean?
Aspect ratio is the relationship between an image’s width and height. Keeping it preserves the shape of the image while resizing.
Can I enlarge a small image?
You can enter larger dimensions, but enlarging does not restore missing detail and may make the image look softer.
Which formats are supported?
The browser must be able to decode the image. Common formats such as JPG, PNG, and WebP are supported in modern browsers.
