Your files never leave your device

Think CONVERT does all of its work inside your web browser. There is no upload step, so there is nothing for us to store, look at, leak or delete.

How it works

When you open a file, your browser reads it from your device into memory. The converters are code that runs on your device. When you save, the new file is made on your device and goes to your Downloads or Files.

Close the tab and everything you opened is gone. We don't keep copies, and we never had any.

A rule that blocks uploads

Every page on this site is sent with a security policy that tells your browser it may only talk to thinkconvert.app itself. Even if something tried to send your files to another website, your browser would refuse.

Why it matters for these files

The files people convert here are often the most personal ones: contact lists, customer exports, bank and accounting CSVs, calendars, and GPS tracks that start and end at home. Most online converters upload them to a server you know nothing about. Here they stay with you.

Check it yourself

1. Open your browser's developer tools and choose the Network tab.
2. Open a file in Think CONVERT and convert it.
3. You'll see no request carrying your file. You can even turn on flight mode after the page has loaded and it keeps working.

What we do collect

We count page visits with Cloudflare Web Analytics. It uses no cookies, doesn't track you across sites, and only receives the page address and how long it took to load. It never sees your files. This is the one other address your browser is allowed to contact. We don't sell data, and we don't need an account from you.
