Most online file tools upload your documents to their servers. themgdev is built the opposite way: the tools run inside your browser, so your files stay with you. Here's exactly how that works.
Our PDF and image tools run on your own device using JavaScript and WebAssembly. Your files are opened, edited and saved locally — they are never sent to our servers.
Because processing is client-side, there is no upload step for these tools. That means no file sits on a server waiting to be processed, cached, or intercepted.
We don't keep copies of your documents. When you close the tab, the file and everything derived from it is gone from memory.
Your files are never used to train models, sold, or shared with third parties. They're yours.
Exports are standard files with no watermarks and no hidden tracking added.
The site is served over HTTPS with modern security headers and a strict content security policy.
The vast majority of themgdevtools are fully client-side. If we ever add a tool that genuinely needs server processing, we'll say so clearly on that tool's page, process the file over an encrypted connection, and delete it immediately after — never storing or reusing it.
