Resize images to any dimension by pixels or percentage. Lock aspect ratio, preview instantly, and download. Runs 100% in your browser.
About this tool
Resizing changes the actual pixel dimensions of an image, meaning its width and height. Use it to shrink a large camera photo down to web size, hit an exact pixel requirement for a profile picture or banner, or scale a graphic by percentage.
Lock the aspect ratio to keep the image from stretching, or unlock it to resize width and height independently. All resizing happens in your browser, so nothing is uploaded.

Frequently asked questions
How do I resize an image to exact pixel dimensions?
Enter the exact width or height you need in pixels. With aspect ratio locked, the other dimension is calculated for you so the image stays in proportion.
How do I resize without stretching or distorting the photo?
Keep the aspect ratio locked. The tool then scales width and height together, so circles stay round and faces stay natural.
What is the difference between resizing and cropping?
Resizing scales the whole image up or down. Cropping cuts away part of the image to change its framing or shape. Use the Crop Image tool when you want to remove edges instead of scaling.
Will enlarging a small image make it blurry?
Scaling an image far beyond its original size can soften detail because there is no extra information to add. For moderate enlargements, try the Upscale Image tool, which uses higher-quality interpolation.
