Extract text from compiled UI files (QMLC)
To convert QMLC UI files to another format, you need Qt Creator or other Developer software.
To convert other file formats to the "Compiled Source Code File" file type, you need software like Qt Creator or a similar tool.
The .QMLC file is a compiled binary cache of a QML (Qt Meta Language) source file. It is primarily used by the Qt Framework to speed up the loading time of user interfaces in cross-platform applications built with Qt Creator. When the Qt engine runs a script, it compiles the source text into this binary format for faster execution.
The main disadvantage of the .QMLC format is its closed, compiled nature. Because it is a binary cache, you cannot open or edit it using standard text editors. If you try, you will only see garbled characters. Furthermore, these files are heavily tied to the exact version of the Qt engine that compiled them, meaning they often fail to run if transferred to a different environment.
Users usually want to convert a .QMLC file back into a QML file to recover and edit the original source code. Standard online converters fail completely here, as this is a proprietary binary, not a standard document. Reversing the compilation process is notoriously difficult and requires specialized, version-matching decompilers.
This file format is exceptionally difficult to open or convert because it is not meant for human interaction. Often only the original software can properly read or execute the data. Despite this, just drag and drop your file to see what it is and convert it if supported. convert.guru can safely inspect your .QMLC file, extract readable text or variable names, and help you analyze its internal contents without needing to install a massive development environment.
Convert.Guru analyzes your QMLC file, detects the exact format, and lets you read the text inside.
Users also converted QML, TMP, QMLTYPES, LC and BDM files.
If you want to convert QMLC file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Qt Creator or similar software from the "Compiled UI Source Cache" 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 QMLC, try Qt Creator or another comparable tool in the "Compiled UI Source Cache" category.
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 QMLC converter.
