About Resize Image
This free tool lets you resize an image online by changing its width and height. Enter new sizes in pixels, or scale the picture by a percent to make it larger or smaller. The tool runs inside your browser, so your photo is never uploaded, and it works on both phones and computers.
Use it when a form asks for a photo of a set size in pixels, when you want images to fit a website or online shop, or when you need a smaller picture for a profile or post. Making an image smaller in pixels also reduces its file size, which helps with slow uploads.

Frequently asked questions
How do I change the pixel size of a photo?
Choose your photo, type the width and height you need in pixels, and download it. You can also scale it by percent instead.
What is the difference between resizing and compressing?
Resizing changes the width and height in pixels. Compressing keeps the dimensions but makes the file smaller in KB.
Is my photo private?
Yes. The image is resized on your device and is never sent to a server.
The form wants a size in KB, not pixels. What now?
Use Resize Image to KB to hit a file size like 20KB, 50KB or 100KB.
