Find and Replace Text Online - Professional-Grade Text Editing

Whether you are cleaning up a document, refactoring code, fixing repeated typos, or transforming data, find and replace is one of the most essential text-editing operations. This tool brings the power of a desktop text editor's find-and-replace to your browser - with live match highlighting, match-by-match navigation, regex support with capture groups, and a detailed diff summary.

Unlike basic online replacers that just swap text blindly, this tool shows you exactly where every match is before you replace anything. Navigate through matches one at a time, preview highlights, then choose to replace individually or all at once.

Key Benefits

Live Match Highlighting
See every match highlighted in amber as you type your search term. The current match stands out in purple for easy navigation. No guessing where your matches are.
Match Navigation
Step through matches one by one with Previous/Next buttons. "Match X of Y" shows your position. The view auto-scrolls to each match - like a desktop editor in the browser.
Regex + Capture Groups
Full regular expression support with $1, $2... capture group references in the replacement. Reformat dates, extract patterns, or perform complex text transformations.
100% Private
Everything runs in your browser. Your text never leaves your device - no server processing, no storage, no tracking. Safe for confidential documents and sensitive data.

How to Use (Step-by-Step)

1
Paste your text
Copy text from any source and paste it into the input box. The tool supports up to 100,000 characters.
2
Enter the search term
Type what to find in the "Find" field. Matches highlight instantly in the preview. The badge shows the match count in real-time.
3
Set options and replacement
Toggle Case Sensitive, Whole Word, or Regex Mode as needed. Enter your replacement text. For regex, use $1, $2 to reference capture groups.
4
Replace and copy
Use Replace All to swap everything, or Replace Next to go one by one. Review the diff summary, then copy the result.

Technical Notes

The find field is compiled as a JavaScript regular expression with the global flag. If Case Sensitive is off, the case-insensitive flag is also added. Use standard regex syntax like \d for digits, \w for word characters, [a-z] for character classes, and parentheses for capture groups. Reference groups in the replacement with $1, $2, etc.

Whole Word matching adds word boundary anchors (\b) around your search term. This means searching for "cat" will match "cat" but not "category" or "concatenate". It is automatically disabled when Regex Mode is on, since regex users can add their own boundary markers.

Replace Next replaces only the currently highlighted match (shown in purple). After replacing, the tool re-scans the text and advances to the next match. This lets you cherry-pick which occurrences to replace while skipping others - something most online tools cannot do.

If your regex pattern is invalid, the match badge turns red and shows "Invalid regex". The Replace buttons are disabled until you fix the pattern. The tool catches regex compilation errors gracefully - it never crashes or hangs on bad patterns.

Use Cases & Examples

📝
Document Editing
Fix repeated typos, update brand names, or change terminology across an entire document. Use whole-word matching to avoid accidental partial replacements.
💻
Code Refactoring
Rename variables, update API endpoints, or change import paths. Regex mode with capture groups handles complex patterns like reformatting function signatures.
📊
Data Cleanup
Normalize date formats, strip unwanted characters, or transform CSV columns. Use regex like (\d{4})-(\d{2})-(\d{2}) → $3/$2/$1 to reformat dates.
✍️
Content Publishing
Update year references, change product names, or replace placeholder text before publishing. The match preview ensures nothing is missed.

FAQs – Find & Replace Text

Yes, completely free with no limits on usage, no sign-up, no ads, and no premium tier. All features including regex mode, match navigation, and diff summary are included.

All processing happens locally in your browser using JavaScript. Your text is never sent to any server, stored in any database, or tracked in any way. Close the tab and everything is gone.

All matches are highlighted in amber in the preview area. The current match (the one Replace Next will affect) is highlighted in purple. As you navigate with the Previous/Next buttons, the purple highlight moves and the view auto-scrolls to it.

Yes. Use the Replace Next button to replace only the currently highlighted match, then advance to the next one. This lets you cherry-pick which occurrences to replace and skip others.

In Regex Mode, use parentheses in the Find field to capture groups. Reference them in the Replace field with $1, $2, etc. For example, find (\d{4})-(\d{2})-(\d{2}) and replace with $3/$2/$1 to convert 2025-01-15 to 15/01/2025.

The match badge turns red and shows "Invalid regex". The Replace buttons are disabled. The tool catches the error gracefully - it never crashes or hangs. Fix the pattern and matches will update instantly.

Whole Word adds word boundary markers around your search term. Searching for "cat" matches the word "cat" but not "category" or "concatenate". It is disabled when Regex Mode is on because regex users handle boundaries manually.

The tool accepts up to 100,000 characters. A limit indicator below the input turns amber at 80% and red at 95%. Text beyond the limit is automatically trimmed.

Yes. The interface is fully responsive - toggle pills stack vertically, buttons go full-width, and the preview area adjusts its height on smaller screens.

After each replace operation, the summary shows three metrics: total occurrences replaced, characters changed (difference in length), and original vs result character counts.
