Encode URLs and text for safe web transmission
Component Encoding: Encodes special characters in URL parameters (most common)
Full URI Encoding: Encodes only characters not allowed in URIs (preserves URL structure)

A URL encoder/decoder converts between human‑readable text and percent‑encoded forms so reserved characters travel safely in query strings and paths. Use this tool to debug redirects, normalize query parameters, and prepare values for APIs and OAuth callbacks without double‑encoding.
URLs can safely carry only a subset of ASCII. Characters like spaces, quotes, and non‑ASCII glyphs must be percent‑encoded as %HH hex bytes. For example, space becomes %20, ü in UTF‑8 becomes %C3%BC. Decoding reverses this for display.
Paste a string or query component to encode or decode it. The converter uses UTF‑8 and preserves reserved characters appropriately so your output matches browser and server implementations. It’s ideal for building canonical query strings, sanitizing logs, and fixing broken redirects.
Use this utility to debug redirects, build query strings, and sanitize logs before sharing. Accurate encoding prevents subtle bugs and security issues caused by ambiguous characters.
Correct URL handling is foundational for web reliability and security. Use this page to verify edge cases and standardize behavior across services.
