URL Encoder Decoder

Encode full URLs, encode query parameter values, or decode percent-encoded text while keeping the source and result easy to compare.

Decode tracking links, encode query values, or compare readable and percent-encoded URL text.

Component mode helps query values with ampersands, equals signs, hashes, spaces, or Unicode.

  • Encode or decode URL text in your browser
  • Switch between full URL and component handling
  • Swap input and output for repeated cleanup

How to use URL Encoder Decoder

Pick the correct mode before processing so reserved URL characters are handled the way your destination expects.

  1. 1

    Paste the URL or component

    Enter the full URL, query string, parameter value, path segment, redirect target, or percent-encoded text you need to inspect. Keep the original visible until the output has been checked.

  2. 2

    Choose encode, decode, and component mode

    Use encode for readable text that must become URL-safe, decode for percent-encoded text that needs inspection, and component mode when the input is a query value or path segment instead of a full URL.

  3. 3

    Copy, swap, or refine the result

    Process the input, check characters such as spaces, %, &, =, ?, #, and +, then copy the output or swap it back into the input when you need another pass.

Full URL encoding mode

Full URL mode keeps URL structure characters such as colon, slash, question mark, hash, and ampersand readable while encoding unsafe characters.

Component encoding mode

Component mode encodes reserved characters inside a query value or path segment, which is safer for values that will be inserted into a larger URL.

Encode and decode workflow

Switch between encode and decode, process the text, then compare input and output before reusing the URL in a browser, API request, form, or redirect.

Swap for repeated cleanup

The swap control moves output back into the input and flips the mode, making repeated encode and decode checks faster.

Private browser processing

Normal URL encoding and decoding happens in the browser session without an account, which is useful for quick checks on draft URLs and API parameters.

Copy-ready output

The result is shown in a copy-friendly output area with long URLs wrapping visibly so reserved characters can be reviewed before copying.

URL Encoder Decoder privacy and processing

URL Encoder Decoder keeps the input, selected mode, output, storage behavior, and account requirement visible so encoded or decoded text can be reviewed before copying.

Processing Browser

URL Encoder Decoder uses browser URL encoding functions to process the input as a full URL or as a URL component, then shows the result for review and copy.

Storage None

Normal URL Encoder Decoder use does not create a stored server copy of the pasted URL, query string, decoded text, or encoded output.

URL Encoder Decoder account access

URL Encoder Decoder does not require an account. Keep the tab open while you finish because unsaved input and output can clear on refresh.

Before You Use URL Encoder Decoder

Review these notes before decoding unknown links, encoding API values, or copying the result into production code, analytics tags, redirects, or forms.

Privacy

URLs can contain access tokens, email addresses, customer IDs, search terms, redirect targets, or campaign details. Remove sensitive values before pasting when possible.

Normal processing happens in the browser, but decoded URLs can reveal hidden values. Treat the output as sensitive until you know what it contains.

Accuracy

Choose full URL mode for a complete URL and component mode for a query value or path segment. The wrong mode can leave reserved characters unescaped or over-encode the URL structure.

Malformed percent escapes can fail during decoding. If decoding fails, look for stray percent signs, incomplete hex pairs, or copied text that was truncated.

Compatibility

This tool uses standard browser encoding functions. It does not convert plus signs into spaces for form bodies, and it does not offer alternate character set selection.

Encoding makes text URL-safe, but it does not validate that a link is trustworthy, reachable, or safe to open.

Output

Review reserved characters in the output before using it. Spaces should usually appear as %20, while component mode should encode characters such as &, =, ?, and #.

Test the final value where it will be used, such as the browser address bar, API client, redirect rule, analytics tag, or form submission.

Limits

URL Encoder Decoder works in the active browser workspace; very large pasted values may slow encoding, decoding, copying, or the output preview.

URL Encoder Decoder is not a URL parser, link safety scanner, redirect checker, or request builder. It only converts text between readable and percent-encoded forms.

Very large values may slow the browser while processing or rendering wrapped output.

Questions about URL Encoder Decoder

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

Full URL mode is for complete URLs and preserves URL structure characters. Component mode is for query values or path segments and encodes reserved characters such as &, =, ?, #, and /.

When should I decode a URL?

Decode when you need to read a percent-encoded query string, redirect target, tracking link, API parameter, or copied browser URL before deciding whether it is correct or safe to reuse.

Does URL Encoder Decoder upload my links?

Normal use runs in the browser and does not require sign-in. Still treat URLs as sensitive because they can include tokens, emails, IDs, or hidden redirect destinations.

Why did URL decoding fail?

Decoding can fail when the input contains malformed percent encoding, such as a lone percent sign or an incomplete hex sequence. Recopy the value and check for truncated text.

Does encoding make a link safe to open?

No. Encoding only changes how characters are represented in a URL. Inspect decoded destinations carefully and use a link checker or security workflow for unknown or suspicious URLs.
