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