If you search the Chrome Web Store for "find and replace" you'll find dozens of extensions, ranging from abandoned projects last updated in 2018 to actively developed tools with strong feature sets. We tested them all so you don't have to.
Our evaluation criteria: feature depth, regex support, multilingual handling, privacy posture, UI quality, and whether the extension is still actively maintained.
The contenders
We narrowed the field to five extensions worth discussing seriously:
- Rewritr — the extension this article is published by (we'll be transparent about this below)
- Word Replacer II — one of the oldest and most-installed in the category
- Text Blaze — primarily a text expansion tool with some replacement features
- Page Manipulator — developer-focused, highly flexible
- Find & Replace for Text Editing — simple, lightweight, no-frills

Deep dives
Word Replacer II
The most-installed extension in this category with hundreds of thousands of users. It works reliably for simple literal replacement, and its longevity means it's well-tested in the wild. The problems: it hasn't been updated since 2022, its regex support is ASCII-only (so non-Latin scripts break unpredictably), word boundaries use \b rather than Unicode property escapes, and there's no smart case or contenteditable support. For straightforward English-only use it remains fine, but it's showing its age.
Text Blaze
Text Blaze is primarily a text expansion tool — you type a shortcode and it expands to a template. That's a different use case from text replacement (find-and-replace on existing page content), though there's some overlap. It requires an account, syncs to the cloud, and the free tier has rule limits. For browser-side find-and-replace specifically, it's not the right tool. For snippet expansion in forms and editors, it's excellent.
Page Manipulator
Developer-focused and powerful, with CSS and JavaScript injection alongside text replacement. If you need to modify page styling or behaviour in addition to text, it's worth exploring. For pure text replacement without the complexity, it's overkill and the UI reflects that.
Find & Replace for Text Editing
Lightweight and does exactly what the name says — literal find and replace, nothing more. Last updated in 2020. No regex, no multilingual support, no dynamic mode. Fine for occasional simple replacements on ASCII content.
Privacy analysis
Privacy is underappreciated as a criterion for browser extensions. An extension that intercepts page content technically can exfiltrate everything you read. Here's what we found:
- Rewritr — no network requests, verified by inspecting the extension's source. Rules stored in
chrome.storage.synconly. - Word Replacer II — similar approach, no network calls in the extension source.
- Text Blaze — requires account and syncs data to servers by design. Privacy policy is detailed and the team is reputable, but it's a fundamentally different trust model.
- Page Manipulator — no data collection found in inspection.
- Find & Replace — no data collection.
The verdict
For most people who need browser text replacement in 2025, the choice comes down to use case:
- Best all-around: Rewritr — Unicode regex, smart case, contenteditable toggle, bookmarks, actively maintained, fully private.
- Best for snippet expansion (different use case): Text Blaze — if you need templated shortcuts in forms and editors rather than page rewriting.
- Best legacy option: Word Replacer II — if you're already using it for simple English-only replacement and it meets your needs.
- Best for developers needing full page control: Page Manipulator — if you need CSS/JS injection alongside text.
