Tools
Free utilities I built for my own work as a creative developer, shared as-is. Everything runs on this site — no signups, no uploads kept, no nonsense.
Text & Data
Cron Expression Explainer
Type a cron schedule, get plain English, a field breakdown, and the next run times.
Number Base Converter
Convert numbers between binary, octal, decimal, and hex — any size, via BigInt.
Hash Generator
MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests of any text, computed in your browser.
Unix Timestamp Converter
Epoch seconds, millis, or micros to human dates and back — with a live current timestamp.
Images & Icons
App Icon Set Generator
One image in, complete icon sets out — PWA, Expo / React Native, and Android, with JSON configs.
Audio & Video
Audio Converter
Convert audio between MP3, WAV, AIFF, FLAC, OGG, M4A, and Opus — or extract audio from video. Runs in your browser.
Generators
Strong Password Generator
Strong password generator. Cryptographically secure random passwords created entirely in your browser — nothing is sent to a server.
UUID v4 Generator
UUID v4 generator. Create one or many random universally unique identifiers, generated locally in your browser.
Random Hex Color Generator
Random hex color generator. Create random #RRGGBB color codes for palettes, placeholders, and inspiration.
Random Hex String Generator
Random hex string generator. Create cryptographically secure random hex bytes for tokens, keys, and salts — all in your browser.
Lorem Ipsum Generator
Lorem ipsum generator. Create paragraphs of placeholder text for mockups and layouts.
Random Name Generator
Random name generator. Create realistic placeholder names for mockups, tests, and sample data.
Random Email Generator
Random email generator. Fake addresses on reserved example domains — safe for mockups, seeds, and form testing because they can never be real inboxes.
Random Phone Number Generator
Random phone number generator. Fictional US numbers from the reserved 555-01XX range, so they never reach a real person.
Random IP Address Generator
Random IP address generator. Create IPv4 addresses, private-range addresses, or IPv6 addresses from the reserved documentation prefix.
Random MAC Address Generator
Random MAC address generator. Locally administered addresses that never collide with real hardware vendors.
Test Credit Card Number Generator
Test credit card number generator. Luhn-valid numbers for Visa, Mastercard, Amex, and Discover — they pass checkout form validation but aren't issued cards, so they can't be charged.
Random Date Generator
Random date generator. Create random ISO dates within a year range for fixtures, seeds, and sample data.
Color & Shaders
Procedural Shader Palette Generator
Create customizable color palettes for GLSL shaders using a simple cosine-based formula.
