Why use this?

All sizes at once

Select multiple presets and hit Generate — get every thumbnail size in one shot. Download individually or grab all as a ZIP. Perfect for WordPress, Shopify, app icons.

Smart Crop vs Fit

Smart Crop fills the square perfectly, trimming edges. Fit shows the full image with padding. Stretch forces exact dimensions — avoid for faces.

100% private

Everything runs in your browser using the Canvas API. Your image never touches any server. Works offline once the page loads.

WebP saves bandwidth

Thumbnails appear everywhere on a site — switching to WebP cuts file size by 25–35% vs JPG with no visible quality loss. Faster pages, better Core Web Vitals.
