Frequently asked questions
Is MIME Type Finder free to use?
Yes. MIME Type Finder is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does MIME Type Finder upload your file to a server?
No. MIME Type Finder 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?
MIME Type Finder 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 MIME Type Finder?
No installation is needed. MIME Type Finder runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use MIME Type Finder on a phone or tablet?
Yes. The MIME Type Finder 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. MIME Type Finder keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
