FAQ

Is this converter offline?

Yes. The conversions run in your browser and the tool does not make network requests.

Does Base64 encode handle Unicode (e.g., emojis, non‑Latin text)?

Yes. It uses UTF‑8 encoding before Base64 conversion, so Unicode text is supported.

Why does URL decode sometimes fail?

If the input contains invalid percent-encoding (like a stray “%”), decoding throws an error—fix the encoding or re-encode first.

What’s the difference between JSON pretty print and minify?

Pretty print adds indentation and line breaks for readability; minify removes whitespace to make JSON compact.

What does HTML escape do?

It converts characters like < and & into safe entities so text can be embedded in HTML without being interpreted.

How is slugify generated?

The tool lowercases, removes diacritics, keeps letters/numbers, and turns other runs into single hyphens.

Can I chain multiple conversions?

Yes. Convert once, then use Swap to move the output into the input and run the next conversion.
