Image Resizer
Resize images to exact pixel dimensions with optional aspect-ratio lock.
Your image is resized locally in your browser and never uploaded.
What is image resizer?
Set a target width and height in pixels and the resizer scales your image using the browser’s high-quality smoothing. Lock the aspect ratio to avoid distortion, or unlock it for exact dimensions.
Output is PNG, so resized graphics stay crisp with no added compression artifacts.

Frequently asked questions
Yes, but enlarging cannot add real detail — the browser interpolates pixels, so big upscaling looks soft. Downscaling gives the best results.
