What is Convertly?

Convertly is a free, browser-based file conversion tool. It lets you convert PDFs to images, images to PDFs, merge, split, compress and rotate PDFs, and convert or resize images between formats — all without uploading anything to a server.

How it works

Every conversion runs entirely in your browser using open-source JavaScript libraries including PDF.js, pdf-lib, jsPDF, JSZip, and the Canvas API. Your files never leave your device. There are no servers processing your data, no accounts to create, and no files stored anywhere.

Why we built it

I got tired of uploading sensitive documents to random websites just to convert a PDF to an image. Every time I needed to merge two invoices or compress a contract, I had to trust some server I'd never heard of with files I wouldn't want anyone else to see.

So I built Convertly. The idea was simple: what if the conversion happened entirely in your browser, so your files never left your device? Turns out modern browsers are more than capable — PDF.js (the same engine Firefox uses) can render any PDF, and the Canvas API handles image manipulation beautifully.

Convertly is free because it costs almost nothing to run — there are no servers processing your files, no storage costs, no bandwidth for uploads. The tools are open-source libraries doing the heavy lifting right in your browser. I think that's how it should be.
