Base64 Encode / Decode
Free online Base64 encoder and decoder. Unicode-safe, supports URL-safe Base64, and runs 100% in your browser. Nothing is ever uploaded.
URL Encode / Decode
Paste text or a URL below. 'Component' mode encodes every reserved character (for query-string values); 'Full URL' mode keeps :/?&= intact so a whole URL stays clickable.
Private by default: processing stays on your device
Example (component mode)
Input
price=100¤cy=€
Output
price%3D100%26currency%3D%E2%82%AC
These buttons share the page link, not your input.
Want to include your text?
Your current input will be stored in the link after the # symbol, not uploaded to HandyBrowserTools. Anyone with this link can read that text. If you send or post it, the service you choose also receives the link. Do not include passwords or private information.
Frequently asked questions
What's the difference between the two modes?
Component mode (encodeURIComponent) encodes ? & = / and friends. Use it for individual query-string values. Full URL mode (encodeURI) leaves URL structure characters alone. Use it to sanitise a complete URL.
Why do spaces become %20 and not +?
%20 is the standard percent-encoding for a space. The + convention only applies inside application/x-www-form-urlencoded form bodies.
Is anything uploaded?
No, encoding and decoding run entirely in your browser.
