+# Reducing the size of Wasm files
+
+At present, Go generates large Wasm files, with the smallest possible size being around ~2MB. If your Go code imports libraries, this file size can increase dramatically. 10MB+ is common.
+
+There are two main ways (for now) to reduce this file size:
+
+1. gz compress the .wasm file - This reduces things reasonably well. For example, the ~2MB (minimum file size) example Wasm will compress down to around 500kB.
+
+2. Use https://github.com/aykevl/tinygo[TinyGo] to generate the Wasm file instead. TinyGo is a subset of the Go language targeted for embedded devices, and recently added a WebAssembly output target. While it does have limitations (not a full Go implementation), it is still fairly capable and the generated Wasm files are... Tiny. ~10kB isn't unusual. This project is also very actively developed, so it's capabilities are expanding out quickly.
