How the image resizer works
Last updated 10 November 2026
Websites, forms and email often need a smaller picture. Resizing also makes files smaller.
How it works
- Choose the images and type a width, a height or both.
- With the shape kept, the picture is scaled to fit inside your size.
- Download the results.
When to resize
Resizing sets a new width and height in pixels. It is the first thing to do when a form says the picture must be a certain size, when an email bounces for size, or when a web page loads slowly because the pictures are huge.
Keeping the shape
Type a width, a height or both. With the shape kept, the picture is scaled to fit inside the size you gave, so faces do not stretch. If you give only one number, the other follows. Turn the shape lock off only when you really want the picture squashed.
Making a picture bigger
Making a picture bigger does not add detail. The tool has to guess the extra pixels, so the result looks soft. It is better to start with the biggest version you have, and only make pictures smaller.
Quality and privacy
Each save of a JPEG or WebP loses a little quality, so resize once from your original. Resizing removes camera and location details stored in the picture, which is good for privacy when you share photos online. The work happens in your browser and nothing is uploaded.
A good order of steps
- Crop to the right shape with the crop tool.
- Resize to the pixel size you need.
- Compress with the compress tool if the file is still too big.
- Check the result before you upload it.
Things to watch
- Resizing re-saves the picture. JPEG and WebP lose a little quality each time.
- Metadata such as the camera and location is removed, which is good for privacy.
