Developer tool
Your files never leave your device
Check your Network tab and see
Work starts the moment you drop a file
No daily limit, no sign-up, no watermark
If the paste has no http prefix we wrap it as https://x.test/?… so searchParams still work.
In application/x-www-form-urlencoded data a plus sign decodes to a space, and the URL API follows that rule. Some backends treat + literally, so a value that looks off may simply be an encoding mismatch rather than a parser bug.
The tool only reads the string you paste — it never requests the URL, so there is no network call and pasting an internal or signed link is safe.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
Encode or decode query strings with encodeURIComponent — in your browser, nothing uploaded.
Format, validate, prettify and beautify your JSON data instantly.
Test, visualize, and debug Regular Expressions instantly in your browser.
Encode to Base64 or decode from Base64 instantly in your browser.
Decode JSON Web Tokens (JWT) safely to view header and payload without sending secrets to any server.
Format and beautify your messy HTML code instantly in your browser.
