About WAT files
A .WAT file primarily contains WebAssembly Text Format code. It is a human-readable, S-expression based representation of a WebAssembly module. Developers use it to write, read, and debug WebAssembly code before compiling it into a binary format. The official toolchain for managing these files is the WebAssembly Binary Toolkit (WABT). However, the .WAT format has severe limitations for production use. Web browsers cannot execute .WAT files natively; they only understand the compiled binary format. Furthermore, text-based code is highly inefficient for network transfer, resulting in file sizes significantly larger than their binary counterparts. To deploy your code to the web, you must convert .WAT to WASM. For documentation or legacy compatibility, you might convert it to JS or TXT. Just drag and drop your file here to analyze and convert it - free, online, and without installing software. Note that .WAT files are also used as Wafer Acceptance Test data files in semiconductor manufacturing, and as Web Archive Text files by the Common Crawl project. Our tool can analyze your file to determine its exact type and recommend the best conversion path.
Convert.Guru analyzes your WAT file, detects the exact format, and lets you read the text inside.
If you want to convert WAT file to GMT, EST or IST, you can use WebAssembly Binary Toolkit or similar software from the "WebAssembly Text Representation" category. In the File menu, look for Save As… or Export….
To convert files to WAT, try WebAssembly Binary Toolkit or another comparable tool in the "WebAssembly Text Representation" category.
The WAT 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 WAT converter.
