How to Find and Replace Text Online
Follow these steps to find and replace text online using this tool:
- Paste your text into the “Input Text” field. The tool shows a live character and word count as you type.

- Choose your options — enable “Case Sensitive” for exact case matching, or “Whole Words Only” to avoid partial matches.
- For advanced patterns, switch to the “Regex Options” tab. Check “Remove Line Breaks” or “Remove Empty Lines” for quick cleanup, or enable “Custom RegEx” to write your own pattern.

Frequently Asked Questions
Is Replace Text Online free to use?
Yes, completely free. There are no sign-ups, no usage limits, and no ads blocking the interface. The tool runs entirely in your browser, so your text never leaves your device.
Can I find and replace multiple words at once?
Yes. You can add as many find/replace pairs as you need using the “+ Add Pair” button. All pairs are applied sequentially in a single operation, so Pair 1 runs first, then Pair 2 on the result, and so on.
What is a Regular Expression (RegEx)?
A Regular Expression is a sequence of characters that defines a search pattern.
It allows you to match complex text structures — for example, all email
addresses, phone numbers, or HTML tags in a document. This tool supports the
full JavaScript regex syntax, including capture groups ($1,
$2) and flags like g, i, and m.
What does “Whole Words Only” do?
When enabled, the tool only matches standalone words that are bounded by word boundaries. For example, searching for “cat” will match the word “cat” but will not match “category”, “concatenate”, or “scattered”.
How does the Undo and Redo feature work?
Every time you run a replacement, the result is saved to a history stack. You can click “Undo” to go back to the previous result, or “Redo” to move forward again. This lets you experiment with replacements without losing any intermediate results.
Can I save my find/replace pairs for later?
Yes. Click the “Export” button to download your current pairs (including Case Sensitive and Whole Words settings) as a JSON file. To reload them later, click “Import” and select the saved file. This is useful for repetitive tasks like translating content or standardizing formatting.
What keyboard shortcuts are available?
Ctrl+Enter — Run Find & Replace. Ctrl+Shift+C — Copy the output to clipboard. Ctrl+Z — Undo (when not focused on a text field). Ctrl+Shift+Z — Redo.
Is my text data safe?
Absolutely. Replace Text Online runs 100% in your browser using JavaScript. Your text is never uploaded to any server. All processing happens locally on your device, ensuring complete privacy.
