Free URL Encoder

Make any text URL-safe in one click. This free encoder percent-encodes spaces, unicode, and reserved characters — with a choice between full component encoding and gentler full-URL mode that preserves :// structure.

Features

    
Two modes cover both jobs: component mode uses encodeURIComponent for query values and path segments (encoding / ? & = too), while full-URL mode uses encodeURI to preserve the URL’s structure and only encode illegal characters. UTF-8 text encodes to correct multi-byte sequences, and batch mode processes one URL per line.

    
Benefits & Use Cases

    
Developers build query strings with user input safely; marketers encode campaign URLs containing spaces and special characters; anyone generating share links or redirect URLs avoids broken links. Local encoding keeps internal URLs private.

    
Tips

    
Encode values, not whole URLs, when building query strings — encoding the ? and & breaks the structure. That is exactly what the two modes are for: component mode for values, full-URL mode for complete addresses.

  

  

    
Frequently Asked Questions

    
When should I URL-encode text?
Whenever text goes inside a URL: query parameter values, path segments with spaces or unicode, and redirect targets. Encoding guarantees the URL parses as intended.

    
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL structure characters (: / ? # &) and encodes the rest — for whole URLs. encodeURIComponent encodes those too — for individual values placed inside a URL. This tool offers both.

    
Why do spaces become %20 and not +?
This tool uses %20, the universally correct form. The + for space convention only applies to form-encoded query data; %20 works everywhere.

    
Do I need to encode non-English characters?
Yes — URLs are ASCII-only by spec. UTF-8 characters like é or 日 encode to multi-byte % sequences, which browsers and servers decode back correctly.

    
Is my input uploaded anywhere?
No. Encoding runs entirely in your browser — your text never leaves your device.
