Question 1

How do I convert text to binary?

Accepted Answer

Select the Binary format, keep the direction on Text → Code and type your text. Each character becomes an 8-bit group (for example, 'A' becomes 01000001), separated by spaces. For the reverse, paste the binary and switch the direction to Code → Text, it works with space-separated groups or with one continuous run of bits.

Question 2

How does text become hexadecimal?

Accepted Answer

Each character is converted to the hexadecimal value of its Unicode code point (for example, 'A' = 41, '€' = 20AC), with two digits per byte in the ASCII range. Turn on 'Uppercase hex' if you prefer A-F over a-f. When decoding, '0x' prefixes are optional and ignored.

Question 3

Does decoded morse code come back in uppercase or lowercase?

Accepted Answer

Morse has no concept of uppercase or lowercase, it is just dots and dashes. Because of that, decoding always returns lowercase text. When encoding, common punctuation (comma, period, question mark) is converted too, and spaces become a slash ( / ) between words.

Question 4

What's the difference between Base64, Base32 and Base58?

Accepted Answer

Base64 uses 64 characters and is the most compact (33% overhead), ideal for embedding binary data in text (JSON, URLs, emails). Base32 uses 32 unambiguous uppercase characters (no 0/O, 1/I/l), common in 2FA (TOTP) keys and .onion addresses. Base58 removes even more ambiguous characters and font-breaking symbols, and is the standard for Bitcoin addresses. All three are encodings, not encryption: anyone can decode them.

Question 5

What is URL percent-encoding?

Accepted Answer

It's the encoding (RFC 3986) that turns special characters and accents into '%XX' sequences so they can safely travel inside a URL, for example, a space becomes '%20'. This translator encodes as a URL component (equivalent to encodeURIComponent), so characters like '/', '?' and '&' are escaped too.

Question 6

What are HTML entities and when should I use them?

Accepted Answer

HTML entities represent characters that would otherwise have special meaning inside an HTML document, like '<' for '<' and '&' for '&'. They are used to display code or user text inside a page without the browser interpreting those characters as markup, preventing rendering issues and HTML-injection XSS.

Question 7

Are ROT13 and ROT47 safe for hiding information?

Accepted Answer

No. ROT13 and ROT47 are simple substitution ciphers (shifting letters through the alphabet) historically used to hide spoilers, jokes or answers in a reversible way, not to protect sensitive data. Anyone can decode them by applying the same operation again, since both are self-inverse. For real security, use an encryption algorithm, like the AES used by the 'Encrypt Text' tool.

Question 8

What is the NATO phonetic alphabet?

Accepted Answer

It's the standardized set of code words (Alpha, Bravo, Charlie...) used in radio, aviation and military operations to spell letters unambiguously even with noise or accents in the communication. Every letter and digit has a fixed, internationally recognized word (ICAO).

Question 9

Why doesn't decoding leetspeak always return the original text?

Accepted Answer

Leetspeak replaces letters with visually similar digits (E→3, A→4, O→0...), but that relationship isn't always one-to-one, for example, the digit 1 could have originally been 'I' or 'L'. Decoding uses the most common mapping (1→I), so the result is a best-effort approximation, not an exact guarantee.

Question 10

Does the text I type ever leave my browser?

Accepted Answer

No. All 14 conversions run locally in JavaScript, in your browser, nothing is sent to a server. That makes the tool safe for converting passwords, tokens, keys or any sensitive text.
