Chrome has extended the size limit on synchronous WebAssembly compilation on the main thread from 4KB to 8MB. This extension is possible thanks to improvements in the WebAssembly runtime V8. The 8MB limit has been determined through performance measurements on a Google Pixel 1 phone, which is currently considered a representative low-end phone. Future developments in V8 or in hardware may allow to extend the limit further. WebAssembly modules that are bigger than 8MB can be compiled asynchronously with WebAssembly.compile(), or sychronously on a Worker.
