Image Resizer
Resize images to exact dimensions, locally and instantly.
100% private: your image is processed inside your browser and is never uploaded to any server.
About the Image Resizer
The Image Resizer scales any photo to the exact pixel dimensions you need — for avatars, thumbnails, banners, product shots or upload limits. Lock the aspect ratio to resize proportionally without distortion, or unlock it to stretch to a precise width and height. High-quality smoothing keeps downscaled images crisp. As with all Outilo image tools, your file is processed in the browser and never uploaded.
How to use it
- Upload your image.
- Enter a new width or height — with aspect lock on, the other dimension follows automatically.
- Choose an output format and click Resize & download.
Frequently asked questions
Will resizing distort my image?
Not if you keep the aspect-ratio lock enabled. Unlock it only when you intentionally want to stretch to exact dimensions.
Can I make an image larger?
Yes, but enlarging beyond the original resolution can look soft, because there is no extra detail to add.
Is the image uploaded?
No. Resizing happens entirely in your browser using the canvas, so your file stays private.
