URL Decoder (Free, Instant, Decode URLs)

Why Use a URL Decoder?

URL encoding (percent-encoding) converts special characters into %XX format for safe transmission in URLs. Decoding reverses this: %20 → space, %40 → @, %2B → +. Developers decode URLs to read query parameters, debug API requests, analyze tracking URLs, or extract human-readable text from encoded links.

Common Use Cases

• Debug API requests: Decode encoded query params to understand what data is being sent
• Analytics URLs: Decode tracking URLs from Google Analytics, UTM parameters, or ad platforms
• OAuth callbacks: Decode redirect_uri parameters in authentication flows to extract actual URLs
• Email links: Decode encoded email links with tracking parameters to see destination URLs
• Log analysis: Decode server logs with percent-encoded URLs to identify requests

Why This Tool?

• Instant decoding: Paste encoded URLs and decode in milliseconds—no manual conversion
• Full URL decoding: Decodes all percent-encoded characters according to RFC 3986
• 100% client-side: Your URLs never touch our servers—decoding runs in your browser
• Free forever: Unlimited decoding with no rate limits or premium tiers

Pro tip: For encoding text to URLs, use our URL Encoder. If you need to decode Base64-encoded URLs (common in JWTs), try our Base64 Decoder or JWT Decoder.
