How to encode and decode URL strings
Convert spaces, symbols, and query text into URL-safe encoding, or decode encoded links so copied parameters are easier to read.

URLs have reserved characters that can change how a browser reads a link. A space, ampersand, question mark, hash, slash, equals sign, or non-English character may be normal text in one place and URL syntax in another. Encoding turns those characters into percent-encoded text so a search query, redirect target, coupon code, filename, or campaign value can travel inside a link more safely.
Start with the exact text you need to send
Before encoding, decide whether you are working with a whole URL, one query parameter value, or a short text string. For example, encoding a full address will encode characters like : and / too, while encoding only a query value such as hello world & tea keeps the surrounding URL structure separate. That distinction matters when you paste the result into code, a CMS, or an analytics link.
What to enter in ToolBento
Open ToolBento's URL Encode/Decode tool and use the URL or text field. Paste the string you want to inspect, such as a search phrase, a copied callback URL, a redirect value, or an already encoded parameter. Use the value itself rather than a full log line or JSON object unless those extra characters are intentionally part of the string you need to transform.
Press Encode / Decode to see both versions
After the URL or text field contains the value you want to check, press Encode / Decode. The output shows an Encoded version created with URL percent encoding and a Decoded version when the input can be decoded. If the input contains invalid URL encoding, the decoded line reports Invalid URL encoding instead of guessing.
Read encoded query strings without losing the original
Decoding is handy when a link from an email, redirect, ad platform, or support ticket is hard to read because it contains values like %20, %2F, or %3D. Paste the encoded portion, press Encode / Decode, and review the Decoded output before changing anything. Keep a copy of the original link nearby so you can compare the decoded text without accidentally breaking the working URL.
Do not encode the wrong layer twice
Double encoding is a common source of broken links. If a value already contains %20 for a space, encoding it again can turn the percent sign into %25 and produce %2520. That might be correct when nesting one URL inside another parameter, but it is wrong for ordinary link cleanup. If a decoded value already reads correctly, do not keep pressing Encode / Decode and copying the newly encoded layer without a reason.
Common URL encoding mistakes
Do not confuse URL encoding with Base64, HTML entity encoding, hashing, or encryption. URL encoding is reversible formatting for web addresses; it does not hide secrets or validate whether a link is safe. Avoid pasting private reset links, bearer tokens, customer data, or admin URLs into any public page, and always test an important final link in the destination system before sending it to users.
