How to Install Sublandia Editor as Desktop App (PWA) – Offline Subtitle Editing

Introduction

Sublandia Editor can be installed as a Progressive Web App (PWA) on your desktop, allowing you to work offline and edit subtitles securely.

While Sublandia Editor runs in your browser, installing it as a desktop app provides:

• offline access without an internet connection
• faster startup and dedicated workspace
• all subtitle and video files processed locally on your device
• full functionality of the web version

This feature is ideal for professional subtitlers who need secure, high-performance, and offline-capable subtitle editing.

 

 

1. Open Sublandia Editor

Open studio.sublandia.com in a modern browser (Chrome, Edge, Firefox or other).

2. Install Sublandia Editor as PWA

Click the Install icon in the address bar (or in Chrome/Edge: “Install Sublandia Editor”).

3. Confirm

Confirm the installation prompt. Sublandia Editor will now appear as a desktop app.

4. Lunch the app

Launch the app from your desktop, start a new project, or continue editing existing subtitle files.

Tip

Installing Sublandia Editor as a PWA does not upload your files. All video files, subtitle files, and templates remain on your computer.
