How to Find and Replace Text Online
- 1
Paste or Type Your Text
Enter the text you want to modify into the input field. You can paste content from any source including documents, code files, spreadsheets, log files, or plain text. There is no character limit, so large texts work without issues. - 2
Enter the Search Term or Pattern
Type the word, phrase, or regex pattern you want to find in the Find field. Toggle Case Sensitive for exact capitalization matching, Whole Word to avoid partial matches inside longer words, or Regex to use full JavaScript regular expression syntax for complex pattern matching. - 3
Specify the Replacement Text
Enter the text that should replace each match in the Replace With field. Leave it empty to delete all matches. When using regex mode, you can reference capture groups with $1, $2, and so on to reuse parts of the matched text in the replacement. - 4
Replace and Copy the Result
Click Replace All to substitute every match at once, or Replace First to change only the first occurrence. The result panel shows the modified text with a count of replacements made. Click Copy to send the output to your clipboard, ready to paste into your project.

Why Use Our Text Find & Replace?
Text Find & Replace is a free browser-based tool for searching and replacing text with precision. It supports plain text search, case-sensitive matching, whole word boundaries, and full JavaScript regular expression syntax. Real-time match highlighting shows every occurrence before you commit to a replacement, eliminating guesswork. Whether you need to fix a single typo across a long document or perform a complex pattern transformation on log data, this tool handles it instantly without any software installation or account creation.
The regex mode unlocks advanced capabilities that go beyond simple string substitution. Use capture groups to extract and rearrange parts of matched text, quantifiers to match variable-length patterns, and character classes to target specific character ranges. The replacement field supports backreferences ($1, $2) so you can restructure matched content rather than just swapping it. This makes the tool a practical alternative to command-line utilities like sed or Perl one-liners, accessible to anyone through a web browser.
Text Find & Replace works well alongside other FindUtils text tools. Use the Regex Tester to build and debug complex patterns before applying them here. Compare your original and modified text side by side with the Diff Checker to verify changes are correct. The Case Converter handles bulk capitalization changes, while the Text Line Sorter organizes output lines alphabetically or by custom criteria. For counting words or characters after replacement, the Word Counter provides detailed text statistics.
How It Compares
Most text editors include find and replace, but they require you to open a file first and lack advanced regex features in their free versions. Online alternatives like TextFixer and EditPad offer basic search and replace but do not support regular expressions, capture groups, or real-time match highlighting. Command-line tools like sed and awk are powerful but require terminal access and knowledge of shell syntax that many users do not have.
This tool combines the power of regex-based replacement with the simplicity of a web interface. All processing runs in your browser, so no text is uploaded to any server. There are no usage limits, no account requirements, and no ads. Unlike desktop software, it works on any device with a browser, and unlike command-line tools, it provides a visual preview of every match before you replace. The real-time highlighting and match counter give you confidence that your pattern is correct before committing to changes.
