A Notepad++ style editor that runs in your browser: tabs, syntax highlighting, and auto-save.
Nothing to download or install — it works on macOS, Linux and ChromeOS too.
Notepad++ is a Windows-only desktop program, which is why so many people search for it online: they're on a Mac, on a Chromebook, or on a locked-down work laptop where installing an .exe isn't an option. This is that same habit in a browser tab — a tabbed editor with syntax highlighting for 20+ languages — and every file stays on your own machine.
Each document gets its own tab you can rename with a double-click. Switch between them freely: the scroll position, cursor and folded regions of every tab are restored exactly as you left them.
The official Notepad++ build is a Windows binary. This one needs nothing but a browser, so it opens the same way on macOS, Linux, ChromeOS and Windows — no Wine, no virtual machine, no admin rights.
Colour-coded editing for JavaScript, TypeScript, Python, JSON, XML, HTML, CSS, SQL, YAML, Java, C, C++, C#, Go, PHP, Ruby, GraphQL and more, with code folding, auto-indent, and one-click formatting for structured files.
Opening a file reads it locally; the contents are auto-saved into your browser's local storage and nowhere else. Nothing is uploaded, so pasting a config or a log here doesn't hand it to anyone.
This is an independent browser editor, not a port of Notepad++. Here's an honest account of what carries over, what doesn't, and where the browser wins.
Tabbed, renameable documents; syntax highlighting across 20+ languages; code folding and collapse-all; find and replace with regular expressions (Ctrl/Cmd+F and Ctrl/Cmd+H); auto-indent; multi-cursor editing; word wrap; and a live line, word and character count in the status bar.
The plugin ecosystem (Plugin Admin, Compare, NppExec), recorded macros, find-in-files across a folder, and session files written to disk are desktop capabilities that a browser tab can't reproduce. If your workflow depends on those, keep the desktop app.
No installer, no admin rights, and no updates to chase. It opens in about a second on any operating system, keeps your tabs between visits, and works on machines where you're not allowed to install software at all.
Notepad++ has no native build for your OS. This gives you the tabbed, highlighted editing you were after without emulation or a VM.
Corporate laptops and school computers often block installers outright. A browser tab needs no permission from IT, and nothing you type leaves the device.
Reformat a JSON blob, clean up a CSV column, or read a log file once. Opening a web page is faster than downloading and installing an editor for a five-minute job.
What this is, what it isn't, and how your data is handled.
No. Notepad++ is free open-source software for Windows written by Don Ho, and this site is not affiliated with it. This is an independent editor built on Monaco — the engine behind VS Code — that gives you the same tabbed, syntax-highlighted workflow in a browser, with no install.
Not natively — the official builds are Windows only. The usual workarounds are running it through Wine or in a Windows virtual machine, both of which are a lot of setup for a text editor. Using this page in your browser avoids both.
No. Plugins and recorded macros are desktop features that need access to your operating system, and a web page has none. Everything else — tabs, highlighting, folding, regex find and replace — works here.
Yes. Press Ctrl+F (Cmd+F on macOS) to search and Ctrl+H (Cmd+Option+F on macOS) to replace, then toggle the .* button in the search box to match with a regular expression.
No. There is no download, no extension and no signup. The editor loads as a web page and runs entirely in your browser.
In your browser's localStorage on this device, automatically as you type. They are not synced or backed up anywhere, so use the Download button to save a real file whenever you need a copy.
The plain-language version of this page: a free notepad with tabs and auto-save for notes rather than code.
If you wanted the simple open-and-type notepad, start here instead.
For JSON specifically: format, validate and inspect it in a dedicated view.
