Frequently asked questions

Is GraphQL Formatter free to use?

Yes. GraphQL Formatter is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.

Does GraphQL Formatter upload your file to a server?

No. GraphQL Formatter processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.

Is there a limit on how much input I can use?

GraphQL Formatter handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.

Do I need to install anything to use GraphQL Formatter?

No installation is needed. GraphQL Formatter runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.

Can I use GraphQL Formatter on a phone or tablet?

Yes. The GraphQL Formatter interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.

What happens to your file when I close the tab?

It is discarded. GraphQL Formatter keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
