I built a free browser-based image toolkit with JavaScript

I built a free image toolkit that runs entirely in the browser.

The goal was simple: create image tools that are fast, private and easy to use without uploading files to a server.

Features:

• Compress images
• Convert JPG / PNG / WebP
• Resize images
• Crop images
• Convert images to PDF
• Add watermark

Everything runs locally in the browser using JavaScript.

That means images never leave your device.

Try it here:

I’d love feedback from the community!

a browser-based image toolkit in plain javascript is the accessible path more tutorials should teach - no build step, no wasm cliff. which image ops turned out to need more than vanilla js and canvas?
