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