URL Encoder / Decoder
Convert text to URL-safe percent encoding, decode URL-encoded snippets, and copy the result without uploading raw URLs, query strings, tokens, or output.
Encode URL components for query parameters, decode percent-encoded snippets, and clean small development samples before copying them into docs or tests.
Result
How it works
Choose component or decode mode
Encode a URL component before inserting it into a query string, or decode a percent-encoded snippet when you need to inspect what it contains.
Remove tokens before pasting
Strip access tokens, session IDs, private hostnames, credentials, and customer identifiers before using any browser-based URL helper.
Test the destination URL yourself
Encoding can make a component syntactically safer, but it does not prove a full callback, redirect, or query will work in the destination system.
Examples
Encode spaces
Input: hello world? -> Encode
Output: hello%20world%3F
Decode spaces
Input: hello%20world%3F -> Decode
Output: hello world?
Korean text
Input: 안녕 SOLVEOZA -> Encode
Output: %EC%95%88%EB%85%95%20SOLVEOZA
Query value
Input: q=coffee & tea -> Encode
Output: q%3Dcoffee%20%26%20tea
Callback URL sample
Input: https://example.com/callback?next=/tools -> Encode
Output: Encoded sample URL component for docs or tests
Form-style plus
Input: hello+world -> Decode
Output: hello world
Slash in value
Input: docs/tools -> Encode
Output: docs%2Ftools
Malformed percent
Input: %E0%A4%A -> Decode
Output: Safe validation message
FAQ
Does SOLVEOZA upload my URL text?
No. This URL encoding tool runs in the browser tool flow and does not send raw URLs, query strings, tokens, decoded text, or encoded output to a SOLVEOZA conversion server.
Does SOLVEOZA store URLs or query parameters?
No. Custom analytics may record coarse tool events only, not raw URLs, query strings, tokens, credentials, decoded text, encoded output, filenames, keys, or values.
What is URL encoding?
URL encoding converts characters that may be unsafe or meaningful in URLs into percent-encoded byte sequences, such as a space becoming %20.
Does Encode create a full URL?
No. Encode mode creates a URL component. It is useful for values that will be placed inside a URL, not for validating or building a full address.
Why does Decode turn plus signs into spaces?
Many form-style URL query snippets use plus signs for spaces, so Decode mode normalizes plus signs before percent decoding.
Should I paste access tokens or private URLs?
Avoid pasting access tokens, session links, private URLs, credentials, regulated data, or confidential production values into any web tool unless your policy allows it.
Why does decoding fail?
The input may contain a broken percent sequence or bytes that cannot be decoded as valid text. The tool returns a generic error without echoing the private input.
Can I convert very large URL payloads?
Not in this first browser-safe slice. Input is capped at 512 KiB and converted output is capped at 2 MiB.
