Exploit Payload Encoder
Encode payloads using URL, Double URL, HTML entities, Unicode, Hex, Base64, and UTF-7 encoding. Chain multiple encodings for WAF bypass testing.
---
How to Use the Payload Encoder
- Enter your payload text in the input field.
- Add encoding steps to build a chain (e.g., URL then Base64).
- The chain result updates automatically as you modify the chain.
- Remove encodings from the chain by clicking the 'x' button.
- Use the 'Quick Encode' section to see your payload in all encodings at once.
- Copy any encoded result using the copy button.
About Exploit Payload Encoder
Web Application Firewalls (WAFs) and input filters often block known malicious payloads. Encoding payloads in different formats can sometimes bypass these filters. This tool supports URL encoding, double URL encoding, HTML entity encoding, Unicode escapes, hexadecimal encoding, Base64, and UTF-7. The encoding chain feature lets you apply multiple encodings sequentially, which is useful for testing complex filter bypass scenarios. This tool is designed for authorized security testing to identify weaknesses in input validation.
Frequently Asked Questions
Encoding chaining applies multiple encoding layers sequentially. For example, URL-encoding a payload and then Base64-encoding the result. Some WAFs decode one layer but not multiple, allowing the payload to pass through.
Double URL encoding is useful when an application or proxy decodes URL encoding once before passing the input to a backend that decodes it again. This can bypass first-layer filters that check the URL-decoded input.
