Convert TS to QM

Understanding TS and QM file formats

TS files in the context of software localization are Qt Linguist Translation Source files. These are XML-based files used by the Qt framework to store translations for user interface strings. Developers and translators use TS files to manage and edit translations for applications built with Qt.

QM files are Qt Compiled Translation files. They are binary files generated from TS files and are used by Qt applications at runtime to provide localized user interfaces. QM files are optimized for fast loading and efficient use by the application, but they are not human-readable.

Why convert TS to QM?

Converting a TS file to a QM file is a necessary step in deploying a localized Qt application. While TS files are editable and suitable for translators, QM files are required by the application to display translations to end users.

How to convert TS to QM

The standard way to convert TS files to QM files is by using the Qt Linguist tools, specifically the lrelease utility. This tool is included with the Qt development environment and is available for Windows, macOS, and Linux.

Step-by-step conversion using lrelease

1. Install the Qt SDK from the official Qt website if you haven't already.
2. Open a terminal or command prompt.
3. Navigate to the directory containing your .ts file.
4. Run the following command:
   lrelease yourfile.ts
5. This will generate a yourfile.qm file in the same directory.

Best software for TS to QM conversion

• Qt Linguist: Provides a graphical interface for editing TS files and can export to QM via File → Release.
• lrelease (command-line): The most reliable and widely used tool for batch conversion.

Tips for successful conversion

• Always validate your TS files for errors before conversion.
• Use the latest version of Qt tools to ensure compatibility.
• Automate the conversion process in your build scripts for efficiency.
