Image Resizer

What is Image Resizer?

The Image Resizer scales images to exact pixel dimensions or by percentage. Lock the aspect ratio to prevent distortion, or unlock it for custom sizing. Ideal for preparing images for websites, email signatures, or specific resolution requirements.

How to use

1. Step 1 — Upload your image by dropping it onto the upload area or clicking to browse your files.
2. Step 2 — Enter the desired width and/or height in pixels, or use the percentage slider. Toggle the lock icon to maintain or unlock the aspect ratio.
3. Step 3 — Preview the resized result with the new dimensions shown. Click Download to save the resized image in the original format.

Result

A 4000x3000 photo needs to be 800px wide for a blog post. Enter 800 for width with aspect ratio locked — height auto-calculates to 600. The 12MP image is now perfectly sized for web use.
