nopa Desktop
Open apps in windows, pin favorites on the Dock, drag a file from one app to the next, and find everything where you left it tomorrow — a desktop that opens from a link.

Saved to Files
The result of one app is the starting point for the next.
01
Merge a PDF, remove a background, transcribe a recording — most results are saved to nopa Files automatically instead of getting lost in Downloads, and the rest you can save there in one tap. Come back a week later and they are still there.
02
Open two apps side by side and drag a file from one window onto the other. Or right-click any file and pick “Open with” — a converted PNG goes straight to the background remover.
03
Open a file and nopa offers what fits: split, merge, or compress a PDF; convert or watermark an image; format JSON; transcribe audio. One click opens the app with your file loaded.
A file manager in the browser. Everything stays on your device — nothing is uploaded to our servers.
Folders, search, and previews
Grid, list, or columns. Press Space for a quick look, type to jump to a file, drag to move.
Stored in your browser
Files stay on this device, in your browser. Close the tab, come back tomorrow — everything is where you left it.
Open in the right app
Each file offers what fits: a PDF can split or compress, a photo can convert or remove the background, audio can transcribe.
Backup you can take with you
Export a full backup from Settings → Data and import it on another device. Your data stays yours.
Player, Reader, Files, Notes, Calendar, Tasks, Board, Watermark, Code, Retro Games — plus the rest of the catalog. All local, and offline after the first visit; AI tools, Sega games, and downloadable emoji artwork still need a connection.

Reader
Open and read EPUB and FB2 books — in your browser, nothing uploaded

A fast local code editor with syntax highlighting — no upload, no account.
Retro Games
Play legal homebrew demos or load your own ROM locally in the browser.
Not a pile of tabs — windows, a Dock, and shortcuts that stay out of the way until you need them.
Drag them anywhere, snap two side by side, or minimize to the Dock. Work in more than one app at once, like on a real computer.
Pin the apps you use daily so they are one click away. Whatever is running shows up there too, so you never lose a window.
Drop a photo on the background remover, a PDF on the splitter. Or right-click a file and pick “Open with” to send it to the right app.
Open a file and nopa offers what fits — split a PDF, convert an image, transcribe audio. One click and the app opens with your file ready.
Press ⌘K or Ctrl+K to jump to any app or file by name — no hunting the Dock. It is the fastest way to move around.
A new note, task, or link, or upload a file — straight from the desktop, the way a real operating system works.
nopa is a Progressive Web App. Add it once — it opens in its own window, works offline after the first visit, and can receive files from other apps where your browser allows.
Install nopa
Look for Install / Add to Home Screen in your browser menu. On some browsers, bookmarking is the closest option.
Its own window
No address bar or browser tabs — just nopa. It looks and feels like a desktop app, not a website.
Offline after the first visit
After the first visit the desktop and its apps are cached in your browser, so they open even with no connection.
Open with & Share
On supported devices you can share a file from another app straight into nopa, or set nopa as the app that opens it.
On your home screen & Dock
The nopa icon sits next to your other apps. Tap it and it opens the desktop right where you start.
Save back to the same file
Open a text file from your computer, change it, and save it back to the same place — no second copy in Downloads. Works in Chrome and Edge on a computer.
No email, no plan, no daily cap, and no watermark on anything you make. Nothing to cancel later, because there was nothing to sign up for.
Notes, boards, and Files live in this browser’s storage, not on our servers. Export a full backup from Settings → Data whenever you want to move it or keep a copy.
Because everything is local, clearing your browser data or uninstalling nopa deletes it — back up first. Large files depend on your device’s memory, and AI apps download their model once before they can work.
Yes. The desktop and every app in it are free. There are no paid plans or daily caps.
No. Open the desktop and start — no email, no password.
In your browser on your device. Files are not uploaded to our servers unless a specific app says otherwise.
Yes. After the first visit the desktop and its apps load without a connection. AI models, the Sega emulator core, and downloadable emoji artwork are fetched the first time you use them, so those need the internet once.
Yes. The built-in Player handles audio and video — playlists, resume where you left off, speed control. Play from nopa Files or straight from your device, even a large movie.
Yes. Export a backup in Settings → Data, then import it in nopa on the other device.
A Progressive Web App is a website that installs like a normal app. nopa opens in its own window, works offline after the first visit, and sits next to your other apps — no app store needed.
Use the Install button on this page, or your browser menu. Chrome and Edge show an install icon in the address bar; on iPhone, tap Share and then “Add to Home Screen”.
The desktop loads in seconds. Drop a file or pick an app to start.
