An image resizer changes the dimensions (width and height) of images to your exact specifications. This tool processes images entirely in your browser using the Canvas API — your files are never uploaded to any server.
You can enter exact pixel dimensions for both width and height. The aspect ratio lock feature ensures your image doesn't get stretched or distorted when you change one dimension — the other adjusts automatically to maintain proportions.
Image resizing is essential for preparing images for websites, social media, email, and print. Different platforms have specific dimension requirements, and this tool lets you hit exact targets without installing any software. The tool shows a side-by-side comparison of the original and resized images, along with file size information.

Frequently Asked Questions
Is my image uploaded to a server?
No. All resizing happens in your browser using the Canvas API. Your image never leaves your device.
Does it preserve image quality?
The tool uses high-quality canvas rendering (92% JPEG quality). Enlarging small images beyond their original size may reduce perceived quality.
What is the aspect ratio lock?
When enabled, changing the width automatically adjusts the height (and vice versa) to prevent stretching or distortion.
What is the maximum image size?
This tool supports images up to 20 MB. Output dimensions are limited to 10,000 x 10,000 pixels.
