Convert QML to another file type
To convert QML UI files to another format, you need Qt Creator or other Developer software.
Convert a file to QML
To convert other file formats to the "UI Markup Language File" file type, you need software like Qt Creator or a similar tool.
About QML files
The .qml file extension serves two dominant purposes. Most commonly, it is a Qt Modeling Language (or Qt Quick Markup Language) file used by the Qt Framework to design declarative, JavaScript-like user interfaces. Alternatively, it functions as a QGIS Layer Style file, saving symbol, label, and rendering configurations for spatial data in QGIS. Both variations are typically plain text or XML-based. The primary disadvantage of a .qml file is its strict dependency on its parent ecosystem. A Qt UI file requires the Qt Creator IDE or Qt runtime to execute the visual interface, while a QGIS style file is useless without the exact corresponding map layer and the QGIS application. They cannot be naturally previewed in standard web browsers or generic document viewers. Converting Qt .qml files usually means extracting the text as TXT or XML for code review, as direct conversion to other UI frameworks requires manual rewriting. For QGIS users, converting a .qml file to a standard SLD (Styled Layer Descriptor) is highly recommended for interoperability with other GIS software like GeoServer. Because these files store proprietary property bindings or application-specific XML schemas, standard online converters often fail or corrupt the syntax.
Convert.Guru analyzes your QML file, detects the exact format, and lets you read the text inside.
If you want to convert QML file to LYR, SLD, UI, XML, SHP, PYTHON, HTML, JSON, JS, TS, PY or JAVA, you can use Qt Creator or similar software from the "Declarative User Interface Definition" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to QML, try Qt Creator or another comparable tool in the "Declarative User Interface Definition" category.
The QML Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our QML converter.
