URL Encoder (Free, Instant, Safe URLs)

Why Use a URL Encoder?

URLs can only contain specific ASCII characters (A-Z, 0-9, and a few symbols like - and _). Spaces, special characters (!, @, #, $, etc.), and non-ASCII characters (ñ, ü, 你好) must be percent-encoded (e.g., space → %20, @ → %40) to work in URLs. Without encoding, query parameters break, APIs reject requests, and links fail.

Common Use Cases

• Query parameters: Encode search terms with spaces ("hello world" → hello%20world) for ?q= URLs
• API requests: Encode special characters in GET request parameters (email, usernames with @)
• OAuth & redirects: Encode callback URLs with query params for authentication flows
• Social sharing: Encode titles with special chars for Twitter/Facebook share URLs
• Tracking pixels: Encode URLs with multiple nested query parameters for analytics

Why This Tool?

• Instant encoding: Paste text and encode in milliseconds—no manual escaping
• Full URL encoding: Encodes all special characters according to RFC 3986 standard
• 100% client-side: Your data never touches our servers—encoding runs in your browser
• Free forever: Unlimited encoding with no rate limits or premium tiers

Pro tip: After encoding, use our URL Length Checker to ensure encoded URLs stay under character limits for SMS or social media. For creating URL-friendly slugs, try Slug Generator.
