Image Resizer: Free Online Tool & Complete Guide

What is the Image Resizer?

Resizing images is one of the most common tasks on the web — for email attachments, blog uploads, social media profiles and app assets. Uploading a 5 MB photo when you need a 500 px thumbnail wastes bandwidth and time.

This image resizer lets you shrink or enlarge any image to exact pixel dimensions or a percentage, keep or drop the aspect ratio, convert between PNG, JPEG and WebP, and control output quality. Everything happens locally with the HTML5 Canvas API — your photos never leave your device, and there is no file-size upload limit.
