Yes. .env 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 .env Formatter upload your file to a server?
No. .env 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.

.env 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 .env Formatter?

Can I use .env Formatter on a phone or tablet?
Yes. The .env 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. .env Formatter keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
