How Sublandia Editor Works: Browser-Based Subtitle Editing and Local Processing

Introduction

Sublandia Editor is accessed online but all subtitle editing is processed locally inside your browser. This means that video files, subtitle files such as SRT, TTML, DFXP, WebVTT, ASS, and custom subtitle templates remain on your computer and are not uploaded to external servers during editing.

This browser-based architecture provides an additional level of privacy and control, especially for professional subtitle projects that involve sensitive video content or confidential subtitle files.

In addition to browser access, Sublandia Editor can also be installed as a Progressive Web App (PWA) on desktop devices. This allows users to work directly from their desktop and continue editing subtitles even without an active internet connection.

Local Processing and Data Privacy in Sublandia Editor

When using Sublandia Editor, the application interface is loaded online but all project operations happen directly inside your browser environment.

This includes:

  loading video files

  opening subtitle files

  editing subtitle timing

  applying subtitle rulesets

  exporting subtitle formats

Because processing is performed on the client side:

  video files stay on your local device

  subtitle files are not transferred to remote servers

  subtitle templates remain inside your browser session

  project privacy is maintained during editing

This makes Sublandia Editor especially suitable for professional subtitle workflows where file security matters.

Offline Work with Desktop Installation (PWA)

Sublandia Editor also supports installation as a desktop Progressive Web App (PWA).

After installation, you can:

  launch the editor directly from desktop

  work without opening the browser manually

  continue subtitle editing offline

  use local files without internet access

This is particularly useful for:

  professional subtitle projects

  travel workflows

  offline editing sessions

  stable performance on long subtitle projects
