How to Minify Go Code - Step by Step Guide

Step 1

Input Your Go Code

Let's get your Go code into the minifier! You have several convenient options:

Paste directly: Copy your Go code and paste it into the input editor
Upload a file: Click "Upload" to select a .go or .txt file from your computer
Try the sample: Click "Sample" to load example code and see minification in action

Example: Go Code with Comments and Whitespace

Here's typical well-commented Go code with generous formatting:

// Package main provides user management functionality
package main

// User represents a system user with authentication details
type User struct {
    // Name is the user's full name
    Name   string
    // Email for notifications
    Email  string
    // Active status flag
    Active bool
}

/* ValidateUser checks if user data is valid.
   Returns true if all fields are properly set. */
func ValidateUser(u User) bool {
    return u.Name != "" && u.Email != ""
}
Step 2

Automatic Minification & Compression

The minifier automatically processes your Go code and:

Removes all comments: Strips single-line (//), multi-line (/* */), and doc comments
Eliminates whitespace: Removes extra spaces, tabs, and unnecessary newlines
Preserves functionality: Keeps all code logic, string literals, and required spacing intact
Compacts to single line: Reduces file size dramatically while maintaining valid Go syntax

Example: Minified Output

The same code, now compressed without comments or extra whitespace:

package main
type User struct{Name string;Email string;Active bool}
func ValidateUser(u User)bool{return u.Name!=""&&u.Email!=""}

Result: Reduced from ~450 characters to ~150 characters (66% reduction!)

Step 3

Export Your Minified Code

Get your minified Go code ready for use! Multiple export options make it easy to integrate into your workflow:

Copy to clipboard: One-click copying for quick pasting into your editor or build scripts
Download as file: Save the minified code as a .go file to your computer
Upload files: Drag and drop or browse to minify existing .go files
Size comparison: See exactly how much space you saved with the character count display

Example: Ready for Code Golf or Sharing

Your minified code is compact and ready to share:

package main
import "fmt"
type Config struct{Port int;Host string}
func main(){c:=Config{Port:8080,Host:"localhost"};fmt.Printf("Config: %+v\n",c)}

Perfect for: Code golf competitions, sharing snippets on forums, or demonstrating concepts in minimal space

Frequently Asked Questions

Does minification affect code functionality?

No! Minification only removes comments and unnecessary whitespace. All code logic, string literals, and functionality remain completely intact. The minified code compiles and runs identically to the original.

Are string literals preserved during minification?

Yes! The minifier intelligently preserves all string literals (including spaces), raw strings (backtick strings), and character literals. Only code comments and extra whitespace are removed.

How much size reduction can I expect?

Size reduction varies based on your code's comment density and formatting. Typically, you can expect 40-70% reduction for well-commented code with generous whitespace. Code with minimal comments will see less reduction but still benefits from whitespace removal.

Can I use minified Go code in production?

While technically valid, it's not recommended. Go's compiler optimizes binaries regardless of source code comments or whitespace. Minification is primarily useful for code golf, size-constrained environments, or sharing code snippets. Keep your production code readable!

Does the minifier work with interfaces and generics?

Yes! The minifier preserves all Go syntax including interfaces, generics (type parameters), struct tags, and build constraints. Only comments and excess whitespace are removed.

Is my code secure and private?

Absolutely! All minification happens entirely in your browser using JavaScript. Your Go code is never sent to any server, stored, or transmitted anywhere. It's completely private and secure with no data collection.
