A proper text editor, without the installation.

Sometimes you just need to open a file, change a few lines, or write something down.

EDTR+ gives you the familiar tools of a desktop text editor directly in your browser, without turning a simple task into another app, account, or subscription.

Instant

Open EDTR+ and start typing.

No launch screen, setup, or sign-in.

Local

Your text stays in your browser.

Files you open are processed on your device, not uploaded to our servers.

Capable

More than a basic online notepad.

Tabs, syntax highlighting, find & replace, large file support, previews, and direct file access are built in.

Everything you need from a lightweight editor.

Multiple tabs

Keep several notes and files open at once without juggling windows. Alt+N opens a tab, Alt+X closes one.

Syntax highlighting

Readable highlighting for 20+ programming and markup languages, loaded on demand as you pick one.

Find & replace

Search quickly, replace text, match case, or use regular expressions. Ctrl+F opens it right in the editor.

Command palette

Ctrl+K searches your files, your folders, and the text inside every open document at once, then jumps straight to the matching line. It runs the editor's commands from the same box, and switches the file's language: type json, press Enter, done.

Open real files

Open files from your computer and save changes back to disk when your browser supports it. Ctrl+O to open, Ctrl+S to save.

Large files

Work with logs, datasets, configuration files, and other large text files without turning your browser into a slideshow. Only the lines on screen are rendered, so a 100,000-line file behaves like a short note.

JSON viewer & formatter

Set a file to JSON and a collapsible tree opens next to it, so you can read an API response without counting brackets. Format it, minify it, and when it won't parse, jump straight to the line that broke it.

Markdown & SVG preview

Preview Markdown documents and SVG files directly beside your source. Open a .md or .svg file and the preview appears on its own.

Your text stays yours.

EDTR+ is designed to work locally in your browser. We don't need an account to identify you, and we don't need your documents on a server to edit them.

Your notes remain on your device, and files are opened directly from your computer when supported by your browser.

No account. No cloud workspace. No tracking your documents.

Notepad++ without Windows.

Notepad++ is great, but it is built for Windows.

EDTR+ brings the parts many people use every day to any modern browser: tabs, syntax highlighting, find & replace, file editing, keyboard shortcuts, and a fast place to work with text.

Use it on macOS, Linux, Windows, ChromeOS, or anywhere else you have a browser. No virtual machine. No Wine. No installation.

EDTR+ is an independent open-source project and is not affiliated with Notepad++.

Open it when you need to…

  • Edit a JSON file
  • Inspect a log
  • Fix a config
  • Write Markdown
  • Clean up some text
  • Check a code snippet
  • Take a quick note
  • Open a file without launching a full IDE

EDTR+ is there when a full editor would be too much and a basic textarea would be too little.

Keyboard friendly.

Keep your hands on the keyboard. Tab and panel commands sit on Alt so they never collide with your browser's own shortcuts.

Frequently asked questions

Is EDTR+ free?+

Yes. Completely free. There is no paid version, subscription, or premium tier.

Does EDTR+ show ads?+

No.

Do I need an account?+

No. Just open the editor and start using it.

Is EDTR+ open source?+

Yes. The source code is publicly available on GitHub under an MIT license.

Does EDTR+ upload my files?+

No. EDTR+ is designed to process your text and files locally in your browser. Your notes stay in your browser's local storage on this device.

Can EDTR+ replace Notepad++?+

For many everyday text-editing tasks, yes. EDTR+ supports tabs, syntax highlighting, find & replace, file access, keyboard shortcuts, and other features commonly used in lightweight desktop editors. Notepad++ remains a much larger Windows application with a broader plugin ecosystem and more advanced desktop functionality.

Does it work on macOS?+

Yes. EDTR+ runs in modern browsers on macOS, Windows, Linux, ChromeOS, and other platforms.

Can I edit files directly from my computer?+

On supported browsers, yes. You can open a local file, edit it, and save your changes back to disk. Chrome, Edge and Opera support this through the File System Access API.

Can it handle really large files?+

Yes. The editor renders only the lines visible on screen, so opening, selecting and editing a 100,000-line file feels the same as a short note.

Open. Type. Done.

No installation, account, subscription, or ads. Just a fast, open-source text editor in your browser.
