Randomly
Free random data,
generated instantly. No clutter.
A random data generator for the things you actually need at a desk — a quick word, a password, a list of numbers, a handful of emoji, a batch of UUIDs, IBANs, test card numbers, and more. 131 tools, all using local generation or small samples from our versioned data API. No signup. Local tools process input in your browser; data-backed tools identify their source, and the site's analytics policy is on the Privacy page.
Generators
04 / 04
Word generator
Pull random English words — nouns, verbs, adjectives, or a mix. Useful for naming, ideation, brand sprints.
Number generator
Generate integers or decimals in any range. Set count, allow duplicates, sort the output. Copy as CSV.
Password generator
Strong, memorable, or passphrase-style. Configure length and character classes. Output is generated locally.
Emoji generator
Random emoji, filtered by category. Good for shake-ups in a doc, a Slack message, or a kid's flashcard.
Identifiers
09 / 09
UUID generator
RFC 9562 UUIDs — v4 (fully random) or v7 (time-ordered). Cryptographically random, no collisions.
MAC address
Random MAC addresses for network testing. Locally-administered by default, with optional vendor OUIs.
IBAN generator
ISO 13616 IBANs with valid mod-97 check digits. Country-specific BBAN templates included.
Credit card
Test card numbers with real BIN prefixes, Luhn-valid check digits, plausible expiry + CVV. Format-only.
SSN generator
Format-only US Social Security numbers. Skips reserved area codes (000, 666, 9xx) per SSA rules.
IMEI generator
15-digit mobile device IDs with valid Luhn checksum. Optional real TAC prefixes (iPhone, Galaxy, Pixel).
VIN generator
17-character vehicle IDs (ISO 3779) with correctly computed check digit. Pick a manufacturer prefix.

Hashes & encoding
09 / 09
MD5 hash
Hash any text to a 128-bit MD5 digest. Fast and ubiquitous for checksums and cache keys. Computed locally.
SHA-1 hash
160-bit SHA-1 digest via SubtleCrypto. Still seen in Git and legacy systems. Hashed in your browser.
SHA-256 hash
The SHA-2 workhorse — 256-bit digests for checksums, certificates, and blockchain work. Computed locally.
SHA-384 hash
384-bit digest (SHA-512 truncated), common in TLS cipher suites. Computed in your browser.
SHA-512 hash
512-bit digest, often faster than SHA-256 on 64-bit hardware with a wider margin. Computed locally.
CRC32 checksum
32-bit IEEE 802.3 checksum for catching accidental corruption in zip, png, and Ethernet. Not a security hash.
Caesar cipher
Shift letters to encipher or decipher text. The classic cipher — set shift 13 for ROT13. Runs locally.
Base64 encode
Encode text to Base64, round-tripping full UTF-8. For data URIs, JSON, and email. Encoded locally.
Base64 decode
Decode Base64 back to text, round-tripping full UTF-8. Malformed input is flagged. Decoded locally.
Math & numbers
13 / 13
Roman numerals
Convert numbers to Roman numerals and back, 1–3999, with the subtractive rule. Malformed numerals are rejected.
Number to words
Spell any whole number out in English using the short scale. Handles negatives and zero. Converted locally.
Binary converter
Convert between binary, octal, decimal, and hex. BigInt-backed, so it stays exact for very large numbers.
Bitwise calculator
AND, OR, XOR, NAND, NOR, XNOR, NOT, and shifts on dec, hex, or binary operands. Results in all three bases.
Sum calculator
Total a list of numbers separated however you like, with count, mean, min, and max. Calculated locally.
GCD & LCM
Find the greatest common divisor and least common multiple of two or more integers. Exact via BigInt.
Prime numbers
List the first N primes or every prime in a range, via a sieve of Eratosthenes. Copy as CSV or a list.
Is it prime?
Test any whole number for primality, with the full prime factorization for composites. BigInt-exact.
Fibonacci numbers
Generate the first N Fibonacci numbers — F0 = 0, F1 = 1 — exact for huge terms via BigInt.
Is it Fibonacci?
Check whether a number is in the Fibonacci sequence using the 5n²±4 test, and find its index.
Pi (π) digits
Generate up to 1000 digits of π via Machin's formula in exact BigInt arithmetic. Every digit is correct.
Dice roller
Roll virtual dice from d4 to d20, up to 12 at once. Cryptographically fair, with a running total.
Sequences
Shuffle a range into a random order with no repeats — a permutation for draws, turn orders, assignments.
