Free online text find and replace tool with regex support, case insensitivity, capture group references, and batch text replacement.
TL;DR: Free online text replace tool with regex support, case insensitivity, and capture group references. Batch find and replace text, runs locally with no registration required.
For local tools, open DevTools → Network and search your input — it should not appear in requests.
Usage Guide
Find/replace text locally with optional regex and capture-group rewrites.
1. Use
Paste text, set find/replace flags, preview, copy — work on a copy.
2. Regex
Use capture groups carefully; validate expressions in a regex tester first.
3. Limits
Dialect differences and huge inputs exist; do not regex-parse HTML/JSON.
4. Plain mode
Prefer literal replace for simple renames — fewer accidents.
5. Pipeline
Normalize whitespace → replace → dedupe when needed.
6. Accept
Search for leftovers and keep a pre-replace backup.
FAQ
No. The replacement happens only in the browser on this machine; neither the original nor the result is uploaded. How you store the finished document remains your responsibility.
Yes. Enable regex mode and reference capture groups with $1, $2, and so on to extract and rearrange — for example turning "Last,First" into "First Last". Watch quantifier greediness: the wrong choice swallows too much. Validate complex patterns in a regex tester before replacing here.
Yes. Turn on case-insensitive matching and pair it with the global toggle to process every occurrence in one pass.
For bulk renames of fixed strings, stripping watermark text, or unifying typos, plain text mode is safer. Skip regex when you can — it is kinder to readability and to accident rates.
Browser regex differs from some server-side dialects, so test before reusing patterns across environments; huge inputs can stall the main thread; and do not use regex to "parse" HTML or JSON — reach for a real parser on structured tasks.
Search for the replaced keyword to confirm nothing lingers, spot-check that capture-group rearrangement did not misalign, and keep a pre-replacement copy until downstream confirms. For multi-step jobs, pipeline the work — normalize line breaks and whitespace, then replace, then dedupe — so each step can be rolled back instead of betting on one giant regex.
