Image Resizer
Click or drop an image here (max 20 MB)
About this tool
Resize any image to exact pixel dimensions or by a percentage of its original size. Enter a width and height directly, or type a scale like 50% to halve every dimension. With the aspect-ratio lock enabled the missing side is calculated automatically so your picture never looks stretched or squashed. This is ideal for preparing avatars, thumbnails, hero images and social-media assets that must hit a specific size.
The resize is performed with the HTML canvas drawImage API entirely on your device — the image is never uploaded to any server, so private photos and internal graphics stay private. Files up to 20 MB are supported and the result downloads as a PNG that preserves transparency.
