Free Online Find and Replace Text Tool
Need to swap out a word, fix a recurring typo, or make bulk text changes without opening a code editor? Our free online find and replace tool lets you search for any text string and replace it instantly — with full support for case sensitivity and regular expressions. Paste your text, define what to find and what to replace it with, and you are done.
This tool is perfect for writers editing manuscripts, developers cleaning up data, and anyone who needs to make repetitive text changes quickly. Everything runs in your browser — nothing is uploaded, nothing is stored.
How to Use Find and Replace
Paste your text into the main input area. Enter the word or phrase you want to find in the search field. Enter the replacement text in the replace field. Click replace to make the changes. You can enable case-sensitive matching if "Apple" and "apple" should be treated differently, or enable regex mode for advanced pattern matching.

Tips for Power Users
If you are comfortable with regular expressions, you can do much more than simple text swaps. Use \b for word boundaries to avoid partial matches (finding "cat" without matching "category"). Use capture groups with () and $1 to rearrange text patterns. Even without regex, the case sensitivity toggle is powerful — it lets you replace "iPhone" without accidentally changing "iphone" or "IPHONE."
Frequently Asked Questions
What is regex in find and replace?
Regex (regular expressions) is a powerful pattern-matching syntax that lets you search for complex text patterns rather than exact strings. For example, you can match all email addresses, phone numbers, or dates with a single regex pattern.
Can I undo a replacement?
The tool works on the text in the input field, so you can always paste your original text again to start over. We recommend keeping a copy of your original text before making bulk replacements.
Does this replace all occurrences or just the first one?
The tool replaces all occurrences of the search term by default. This saves you from having to click "replace" multiple times and ensures nothing gets missed.
Is my text sent to a server?
No. All processing happens locally in your browser using JavaScript. Your text never leaves your device, making this tool completely safe for sensitive or confidential content.
