🔎 Find & Replace

Find and replace text with optional case-sensitivity and regex. 100% free, private and browser-based — no sign-up required.

What is Find & Replace?

Find and replace is a core text-editing feature that locates every occurrence of a word or pattern and swaps it for something else. This online version lets you paste any text, define what to search for and what to replace it with, then update every match at once. It saves enormous time compared with editing manually.

For advanced needs, you can enable case-sensitive matching or full regular-expression support, giving you precise control over exactly what gets replaced.

How to Use the Find & Replace

  1. Paste the text you want to edit into the input box.
  2. Enter the term to find and the text to replace it with.
  3. Optionally enable case-sensitive matching or regex mode.
  4. Click Replace All and copy the updated result.

Benefits & Use Cases

Writers correct a repeated name or term throughout a document, developers refactor code snippets, and data workers reformat exported text. Regex mode unlocks powerful transformations such as swapping date formats or stripping specific patterns.

Because the tool runs locally, you can safely process confidential documents and large files without uploading anything.

The Find & Replace is completely free, needs no sign-up or installation, and runs entirely in your browser — nothing you enter is uploaded to a server, so your data stays private. It works on desktop, tablet and mobile, in light or dark mode.

Tips & Best Practices

For a plain word swap, leave regex off and the tool safely treats your search term literally, even if it contains dots or brackets. Turn case sensitive on when you only want to change "US" and not "us", and check the replacement count it reports so you can confirm every match was updated.

Switch on regex for pattern jobs — stripping every number, reformatting dates, or collapsing repeated characters. If you are still shaping the pattern, build and preview it in the Regex Tester first, then paste it here. To compare the before and after, use the Text Diff Checker.

FAQ about Find & Replace

What does case-sensitive matching do?

With case sensitivity on, "Cat" and "cat" are treated as different words. With it off, both are matched regardless of capitalisation.

How does regex mode help?

Regular expressions let you match patterns rather than exact text — for example, all numbers, all email addresses, or words that start with a certain letter.

How many replacements can it make?

All of them. Replace All updates every match in one pass and tells you exactly how many changes were made.

Is my text sent to a server?

No. The find and replace operation runs entirely in your browser, keeping your content private.
