Encode & Decode
Encode and decode URL, HTML, XML, Base32, Base58, Base64 and UTF-8 text. Fix broken links, escape special characters or read an encoded value from a log.
All Encode & Decode
- Base32 EncodeEncode Base32 text, e.g. Hello → JBSWY3DP.
- Base32 DecodeDecode Base32 text, e.g. JBSWY3DP → Hello.
- Base58 EncodeEncode Base58 text, e.g. Hello → 9Ajdvzr.
- Base58 DecodeDecode Base58 text, e.g. 9Ajdvzr → Hello.
- Base64 EncodeEncode Base64 text, e.g. Hello → SGVsbG8=.
- Base64 DecodeDecode Base64 text, e.g. SGVsbG8= → Hello.
- URL EncodeEncode URL text, e.g. a b&c=d/é → a%20b%26c%3Dd%2F%C3%A9.
- URL DecodeDecode URL text, e.g. a%20b%26c%3Dd%2F%C3%A9 → a b&c=d/é.
- JSON URL EncodePercent-encode JSON so it can go in a URL.
- JSON URL DecodeDecode JSON that was percent-encoded in a URL.
- HTML EncodeEncode HTML text, e.g. <b>"Hi"</b> → <b>"Hi"</b>.

- XML EncodeEncode XML text, e.g. Tom & Jerry <3 → Tom & Jerry <3.
- XML DecodeDecode XML text, e.g. Tom & Jerry <3 → Tom & Jerry <3.
- UTF-8 ConvertSee the UTF-8 bytes behind any text.
- UTF-8 DecodeTurn UTF-8 bytes back into readable text.
- Hex to UTF-8Encode HEX-TO-UTF8 text, e.g. 48 65 6c 6c 6f → Hello.
- JSON DecodeUnescape a JSON string back into plain text.
- JSON EncodeEscape text so it fits safely inside a JSON string.
How it works
- Step 1
Pick the encoding below.
- Step 2
Paste your text — results appear instantly.
- Step 3
Copy the output.
Good to know
- Use URL encoding for query strings, HTML encoding for text shown on a page, and Base64 for binary data inside JSON or email.
- None of these hide data — they are all reversible.
- Free, no sign-up
- Runs in your browser
- Works on phones
Frequently asked questions
Are these Encode & Decode free?
Yes. Every one of these Encode & Decode is completely free, with no sign-up, no watermark and no daily limit.
Is the data I paste sent to a server?
No. Conversion runs in JavaScript inside this browser tab and nothing you paste is sent or stored. Even so, avoid pasting live passwords, API keys or private customer data into any website.
Why do I get an error?
Almost always the input isn’t quite valid: a missing comma or quote in JSON, an unclosed tag in XML, or a tab in YAML. The error message shows where parsing stopped — fix that spot, or press “Load example” to compare with input that works.
Does it work on my phone?
Yes. It works in any modern browser on Android, iPhone, tablets and computers — nothing to install.
