Shrink Go binaries by stripping debug symbols with ldflags and compressing with UPX.
Reduce Go binary size by stripping debug info with ldflags and compressing the result with UPX.
go build -ldflags="-s -w" -o myapp main.go
strip myapp
upx --best myapp
The -s flag strips the symbol table, -w removes DWARF debug info, strip removes remaining symbols, and UPX compresses the executable.
Reducing Go binary size shrinks your program by removing unnecessary data like debug symbols and compressing the final file. Think of it like packing a suitcase: you first throw away the packing list and tags (debug info), then vacuum seal the clothes (compression) to take up less space.
