Image Resizer
The Image Resizer changes the dimensions of JPG, PNG, and WebP images, keeping the aspect ratio if you want, and lets you download in your chosen format.
Resize to exact needs
Enter a new width or height and the tool scales your image accordingly. Lock the aspect ratio to avoid stretching, or set both dimensions for a precise fit. It is what you need to meet a profile-photo size, fit an image into a document, or prepare graphics at specific pixel dimensions for a website or app.
Resize down, not up
Scaling an image down keeps it sharp; enlarging beyond its original resolution can look soft, since there is no extra detail to add. Resizing also usually reduces file size as a bonus. Everything runs in your browser. To reduce file size at the same dimensions, use the Image Compressor.
Frequently Asked Questions
Can I keep the aspect ratio when resizing?
Yes. Lock the ratio and changing one dimension adjusts the other automatically to avoid stretching.
Will enlarging an image look blurry?
It can. Scaling beyond the original resolution has no extra detail to work with, so it may appear soft. Scaling down stays sharp.
Does resizing change the file format?
You can download in your chosen format, and resizing typically reduces file size as well.
Are my images processed privately?
Yes. Resizing happens in your browser with no upload.
