Encoding Explorer
See your text in HTML, URL, Base64 and Quoted-Printable — all at once, live.
How it works
Type once and see your text rendered in four common encodings side by side — HTML entities, URL (percent) encoding, Base64 and Quoted-Printable — all updating live as you type. It's a fast way to compare how the same string looks in each format, grab whichever one you need, or figure out which encoding a mysterious string is in by matching its shape. Every conversion runs in your browser; nothing is uploaded.
The four encodings
HTML entities make text safe to place inside a web page. URL encoding makes it safe inside a link or query string. Base64 turns any data into plain letters and digits, common in data URIs and tokens. Quoted-Printable is the mostly-readable encoding used in email. Seeing them together highlights the differences: Base64 obscures the text entirely, while HTML, URL and Quoted-Printable keep readable characters and only escape the tricky ones.
Typical uses
Developers use an explorer like this to prepare a value for a specific context, to sanity-check an encoding while debugging, or to teach and learn how encodings work. Because it shows everything at once, you don't have to switch between separate tools. And since it's all local, you can explore sensitive strings without sending them anywhere.
Frequently asked questions
Are these all reversible?
Yes — each of the four encodings can be decoded back to the original text using its matching decoder tool on this site.
Does it handle accents and emoji?
Yes. Text is treated as UTF-8 throughout, so non-ASCII characters encode consistently in every format.
Is my text uploaded?
No. All four conversions happen in your browser and nothing you type leaves your device.
