Frequently asked questions
Is AZ Tooling really free?
Yes. Every tool on AZ Tooling is completely free with no watermarks, no signup and no artificial limits. Because conversions run on your device instead of expensive servers, there are no per-file costs to pass on to you.
Are my files uploaded to a server?
Never. All conversion engines run inside your browser using WebAssembly. Your files stay on your device the whole time. You can even go offline after the page loads and keep converting.
What file size can I convert?
There is no fixed limit imposed by us. The practical limit is your device's free memory, since processing is local. Most conversions work comfortably with files up to a few hundred megabytes.
Which devices and browsers are supported?
Any modern browser on Windows, macOS, Linux, Android and iOS. Chrome, Edge, Firefox and Safari. Nothing to install.
Is there an API for bulk conversions?
Yes, and it's unusual: an open browser tab IS the server. Generate an API key on the API page and drive bulk conversions from other tabs or scripts, still with zero uploads.
