Everything is one Ctrl+K away.
Ctrl+K opens one search box that looks through your file names, your folder names, and the text inside every open document at once. Pick a result and you land on the matching line.
The same box runs the editor's commands: format, minify, open, save, copy a link to the note. And it switches the file's language: type json, press Enter, and the file is JSON, highlighting and tree view included.
If you've used VS Code, GitHub or Linear, your hands already know this one.
Paste JSON. Read a tree.
Set a file to JSON and a collapsible tree opens next to it, so you can read an API response without counting brackets. Expand or collapse everything at once, or walk it one level at a time.
Format it, minify it, copy it back out. And when it won't parse, the error points at the exact line and column, one click from the spot that broke it.
Alt+P toggles the tree, the same key that toggles the Markdown and SVG preview.
A proper text editor, without the installation.
Sometimes you just need to open a file, change a few lines, or write something down. You know the routine: launch an IDE and wait for it to index a project you don't need, or paste into a bare textarea that forgets everything when the tab closes.
EDTR+ skips all of it. It's the editor at the top of this page. Type, paste, open a file, save it back. The whole thing takes as long as the edit does.

Your text stays in your browser.
Files you open are processed on your device, not uploaded to our servers.

EDTR+ is an independent open-source project and is not affiliated with Notepad++.
Everything you need from a lightweight editor.
Multiple tabs
Keep several notes and files open at once, with folders, drag & drop and per-file download. Alt+N opens a tab, Alt+X closes one.
Syntax highlighting
Readable highlighting for 20+ programming and markup languages, each grammar loaded on demand as you pick one.
Find & replace
Search, replace, match case, or use regular expressions. Ctrl+F opens it right in the editor.
Open real files
Open files from your computer and save changes back to disk in Chrome, Edge and Opera. Ctrl+O to open, Ctrl+S to save. Download works everywhere else.
Large files
Only the lines on screen are rendered, so a 100,000-line log opens, selects and edits like a short note. Your browser never turns into a slideshow.
Markdown & SVG preview
Open a .md or .svg file and a live preview appears beside the source, with Mermaid diagrams, ABC notation and Vega-Lite charts.
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.
Three steps. The first one already happened.
Open
You're on this page, so the editor is already loaded. Scroll up and the cursor is yours.
Type or open a file
Type, paste, or press Ctrl+O to open a file from your computer. Every keystroke is saved as you go.
Save or download
Ctrl+S writes back to the file on disk where your browser allows it. Ctrl+Shift+S downloads a copy anywhere.
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.
The one deliberate exception is Ctrl+F: while the editor is focused it opens find & replace, because that habit is too strong to break. Everywhere else on the page, your browser's find-in-page still works.
And the usual editing shortcuts you already know.
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.
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.
Free means free.
EDTR+ has no paid plan. No premium tier. No trial. No ads. No account. The project is open source under the MIT license and free to use.
If you want to see how it works, report an issue, or contribute, the source code is on GitHub.

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.
What is the command palette?
Press Ctrl+K (⌘K on a Mac) and one search box looks through your file names, folder names and the text inside every open document, then jumps to the matching line. The same box runs editor commands and switches a file's language.
Open. Type. Done.
No installation, account, subscription, or ads. Just a fast, open-source text editor in your browser.
