URL Encoder

Percent-encode any text for safe URLs. Strict component mode for query values, structure-preserving mode for full addresses, plus optional plus-for-space form encoding.

Technical Specifications

Exactly what each mode encodes.

Mode Rule
Component (default) Strict RFC 3986 via encodeURIComponent plus !'()* — only unreserved marks stay raw
Full URL Native encodeURI — structure characters ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) # stay intact
Spaces as + (default off) Component mode only; swaps every %20 for + form-style
Unicode Non-ASCII becomes UTF-8 bytes, each percent-encoded (café → caf%C3%A9)
Already-encoded input Encoded literally: %20 becomes %2520 (use URL Decoder to reverse)
Processing location 100% client-side JavaScript in your browser memory; nothing is uploaded
Usage limit None — encode unlimited texts for free, no signup required

Live Encoding

Every keystroke re-encodes instantly in the selected mode. No button to press.

🔒

Local Device Privacy

Everything runs in your browser with plain JavaScript. URLs never leave your device.

How to Use the URL Encoder

  1. Paste a query value or full URL into the input box.
  2. Output encodes live in Component mode; switch to Full URL for whole addresses.
  3. Enable spaces as + for old-style form payloads if needed.
  4. Click Copy Output or Download .txt to keep the encoded text.
  5. Click Clear to empty both boxes and start over.

Encoding Without Breaking Links

URLs accept only a small alphabet: letters, digits and a handful of marks. Everything else — spaces, ampersands, question marks inside values, non-English text — must be percent-encoded or links break, parameters split early, and servers misread input. Encoding is the difference between a link that works everywhere and one that works on your machine.

Components vs whole addresses

The golden rule: encode values, never structure. A search term of “fish & chips” must become fish%20%26%20chips or the ampersand starts a phantom parameter. But encoding an entire URL the same way destroys its ://, ? and # separators — hence two modes. When in doubt, build URLs from individually encoded parts.

Plus signs, strictness and UTF-8

The +-for-space convention belongs to HTML form submissions only; modern APIs expect %20. Strict encoders also escape !'()*, which browsers leave raw but intermediaries occasionally mangle. Non-ASCII always becomes UTF-8 bytes first — never legacy code pages. To reverse anything here, use the URL Decoder; for markup contexts instead, the HTML Encoder.

Honest limitations

Encoding is literal: already-encoded input double-encodes (%20 → %2520) by design. The tool cannot validate that a URL exists or fix structural mistakes like missing schemes. For very large pastes of tens of megabytes, live encoding on each keystroke can feel slower on older phones.

Privacy and Client-Side Security

Privacy Guarantee: All encoding occurs locally inside your browser. Your text is never transmitted, stored, or recorded on remote servers.

Many online encoders send your pasted URLs to a server for processing — a poor fit for private links, tokens or query data. TinyToolzz takes a different approach: every byte converts in the page itself with plain JavaScript.

Because nothing is uploaded, there is no waiting, no account, and no copy retained anywhere. Your text exists only in the tab's memory and is discarded when you close the page or click Clear.

Frequently Asked Questions

What is percent-encoding?
Percent-encoding replaces URL-unsafe characters with a percent sign plus two hex digits, such as %20 for a space or %26 for an ampersand. It lets any text travel safely inside links, query strings and API calls.
Should I encode a component or a full URL?
Encode components — single query values, path segments, form fields — so their reserved characters cannot break the surrounding URL. Encode full URLs only to sanitize an address for pasting elsewhere; structural characters like : / ? and # stay intact in that mode.
When are spaces encoded as plus signs?
HTML forms historically encode spaces as + instead of %20 in query strings, and many servers accept both. Enable Space as + only for form-style payloads; everywhere else %20 is the correct and unambiguous encoding.
How are non-English characters encoded?
Characters become their UTF-8 bytes, each byte percent-encoded: café turns into caf%C3%A9 and emoji expand to four sequences. Decoding reverses the process exactly, restoring the original text.
Is there a text length limit?
There is no fixed limit. The tool encodes texts of several megabytes in memory. Extremely large pastes (tens of megabytes) may respond more slowly because encoding runs on each keystroke.
Is my text uploaded to a server?
No. All encoding happens locally in your browser with JavaScript. Your text is never transmitted, stored or logged anywhere. Closing the tab or clicking Clear removes everything immediately.
