How it works
Resize photos securely in three simple steps — without uploading to any server.
Upload Securely
Drag and drop any JPG, PNG, WebP, or GIF. Your files never leave your device, ensuring complete privacy.
Set Dimensions
Choose precise custom pixels or pick a social media template. Lock the aspect ratio to prevent distortion.
Download Instantly
Get your perfectly resized image in the format of your choice with an optimised file size in milliseconds.
100% Client-Side Processing
Unlike traditional cloud-based image resizers, ImageSetu uses the HTML5 Canvas API to process images entirely inside your browser. Zero upload time, zero download wait, and complete peace of mind — your data is never transmitted.
Lightning Fast Performance
Our optimised Canvas pipeline handles large multi-megabyte files in milliseconds, delivering perfectly compressed JPEGs, crisp PNGs, or highly optimised WebP files at any resolution you need.
