Find & replace
Swap or remove text across your whole document, right in your browser. Nothing is uploaded.
Files are processed in your browser and never uploaded.
How to use Find & replace
Add your text
Type or paste your text into the input box. Everything is handled by your own browser, so nothing is sent to a server.
Set the options
Choose Find, Replace, Ignore case, Whole word only and Use regular expression. The options are visible from the start, not hidden until you paste something.
Read it and keep a copy
The output updates as you type, so there is nothing to submit and nothing to wait for. Copy result, Don puts the result on your clipboard and Download .txt saves it as a file.
What this tool does
Replace all matches at once
Every match is replaced in one pass, and the result appears in its own box so the original is still there to compare against.
Ignore case and whole-word options
Ignore case and Whole word only stop the replacements you did not intend, which is what usually goes wrong with a bulk find and replace.
Full regular expression support
Use regular expression turns the find box into a full regex, so patterns rather than fixed strings can be matched.
Use captured groups in the replacement
Captured groups can be used in the replacement, so a date or a name can be rearranged rather than simply swapped.
No upload, no sign-up
The text is processed in your browser, so nothing is uploaded, and Copy result or Download .txt gets it back out.
Frequently asked questions
Is my text uploaded anywhere?
No. The find and replace happens entirely in your browser and your text is never sent to a server.
Does it replace every match?
Yes, every match is replaced at once. Leave the Replace box empty to delete each match instead of swapping it.
What does Whole word only do?
It matches your text only when it stands alone as a word, so finding cat will not match inside category or located.
Can I use regular expressions?
Yes. Turn on Use regular expression to search with patterns, and use $1, $2 and so on in the replacement to insert captured groups. Invalid patterns show a clear message.
Will it change my original text?
No. Your text on the left stays as you typed it; the result appears on the right for you to copy or download.
Is there a size limit?
No fixed limit, though very large text or complex patterns are processed in your browser and may be slower on an older device.
