What is Find and Replace?
Find and replace scans a block of text for every occurrence of a search term and swaps it for a replacement — useful for correcting a repeated typo, updating a name or URL that appears many times, or reformatting data pasted from somewhere else.
How to Find and Replace Text Online
- Paste your text. Type or paste the text you want to edit into the box.
- Enter what to find and replace. Type the search term in "Find" and what it should become in "Replace with" (leave it empty to delete matches).
- Adjust the options if needed. Toggle case sensitivity, whole-word matching, or regex mode.
- Copy the result. The replaced text and match count update instantly — copy or download when you're done.
Case Sensitive, Whole Word, and Regex
Case sensitive makes the search distinguish uppercase from lowercase (off by default, so "Cat" and "cat" both match). Whole word only matches your search term as a complete word, not as part of a longer word. Use regex treats the Find field as a regular expression, so patterns like \d+ (one or more digits) work, and capture groups can be referenced in Replace with as $1, $2, and so on.
Frequently Asked Questions
How do I find and replace text?
Paste your text, type what to find and what to replace it with, and every match updates instantly below, along with a count of how many replacements were made.
Is find and replace case-sensitive?
By default, no — matches ignore uppercase/lowercase differences. Turn on "Case sensitive" if you need an exact-case match only.
What does "Whole word" do?
It only matches your search term when it appears as a complete word, not as part of a longer word.
Can I use regular expressions?
Yes — turn on "Use regex" to treat the Find field as a regular expression pattern, including capture groups you can reference in the Replace field as $1, $2, and so on.
What happens if my find text is empty?
The text is left unchanged — an empty search term has nothing to match.
What happens if I enter an invalid regex pattern?
A clear error message appears instead of a broken result, so you know to fix the pattern.
Is my text uploaded anywhere?
No. All matching and replacing happens entirely in your browser — your text is never sent to CurePDF's servers.
Is it free?
