What is the difference between component mode and full-URL mode?

Component mode encodes a single value (like a search term) and escapes everything structural, including / ? & and =. Full-URL mode encodes a whole link but leaves its structure alone — : / ? # & = stay as they are, so the link still works.

When should I encode a URL?

Whenever a link or a value contains spaces, &, =, ? or non-English characters and must travel inside another URL — a search query in a share link, a redirect address, or a form value.

What does a broken % sequence mean?

A % in a URL must be followed by exactly two hex digits (like %20 for a space). A lone % or %2 at the end of a string is malformed, and decoding stops with a clear error instead of silently mangling your text.

Is my URL uploaded or saved?

No. Encoding and decoding happen in your browser; your links never leave the page.

URL Encoder & Decoder

Encode a link or a query value for safe travel — or decode a percent-encoded URL back to readable text.

Private by design: this tool runs entirely in your browser. Your files are never uploaded to a server, and nothing is stored.

Result — 0 characters

How to use it

Paste your URL or value. A whole link, or just the bit that goes inside one.

Pick the mode. Component mode for a single value, full-URL mode for a complete link.

Press Encode or Decode, then copy. Broken % sequences are flagged, not silently mangled.

The one mistake this tool prevents

Most URL bugs come from encoding the wrong thing: encoding a whole link with component rules turns its ? and & into %3F and %26, breaking the link; encoding a value with full-URL rules leaves its & and = live, splitting one value into two parameters. That is why this tool keeps the two modes separate and labelled. Pick the mode that matches what you pasted, and the result is a link that survives sharing, forms and redirects intact.
