How to use this tool
- Paste your text.
- Type what to find and what to replace it with.
- Optionally turn on case sensitivity or regular expressions, then copy the result.
Frequently asked questions
- What does the regular-expression option do?
- With it off, "Find" is matched as plain literal text. With it on, "Find" is treated as a JavaScript regular expression, so you can use patterns like \d+ to match numbers, or capture groups like ($1) referenced in "Replace with".
- Does it replace every occurrence, or just the first?
- Every occurrence in the text is replaced, not just the first match.
- Is my text uploaded anywhere?
- No — the search and replace happen entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — replaced in this tab | Yes, uploaded to process |
| Regular-expression support | Yes, optional | Varies — some tools are plain-text only |
| Account required | Never | Often, past a certain usage level |
