Image Resizer
Resize and crop images without leaving the browser.
What is the Image Resizer?
An image resizer changes a picture's pixel dimensions, optionally cropping to a target shape. Resizing down is the cheapest performance win on most websites, because a 4000px photo displayed at 800px wastes the difference on every single page load.
Frequently asked questions
Will resizing reduce my image quality?
Scaling down is generally safe and often looks sharper once compressed. Scaling up cannot invent detail that was never captured, so an enlarged image looks soft — always start from the largest original you have.
Are my images uploaded anywhere?
No. Resizing happens on a canvas in your browser, so nothing is transmitted. That is what makes it safe for screenshots of internal systems or photos you would not hand to a free web service.
