Resize an Image to Exact Pixel Dimensions
Nujiz Image Resize lets you set a new pixel width and height and create a resized copy directly in your browser. The tool uses high-quality canvas smoothing when the image is redrawn, and the aspect-ratio lock can keep width and height proportional to prevent unwanted stretching.
Resizing is different from file compression. This tool changes the actual pixel dimensions, making it useful when preparing an image for a website, online form, product listing or any layout that requires a specific width and height.
How to Use This Tool
- Choose an image from your device.
- Enter the required width or height in pixels.
- Keep the aspect ratio locked if you want proportional dimensions.
- Process the image and check the resulting dimensions.
- Download the resized copy.
Important Notes for Better Results
Reducing dimensions usually works well, while enlarging a very small source cannot recreate detail that was never present. Start with the highest-quality source available when larger dimensions are required.
Frequently Asked Questions
Can I set an exact width and height in pixels?
Yes. Enter the dimensions you need and the tool creates a resized image at those dimensions.
Can I preserve the original aspect ratio?
Yes. The aspect-ratio lock keeps width and height proportional and helps prevent distortion.
Is resizing the same as compressing an image?
No. Resizing changes pixel dimensions, while compression primarily aims to reduce file size.
Can resizing restore detail in a small image?
No. The dimensions can be enlarged, but details absent from the source cannot be recreated by resizing.
Is the image processed in my browser?
Yes. Image resizing with this tool is performed locally in your browser.
