Generators
Passwords, hashes, UUIDs, QR codes and barcodes. Anything random here uses the browser cryptographic RNG, not Math.random — and because it runs locally, a generated password never travels over the network.
QR Code GeneratorCreate QR codes for links, text and more. Customize colors and size, then download as PNG or SVG — all in your browser.Hash GeneratorGenerate SHA-1, SHA-256, SHA-384 and SHA-512 hashes in your browser.Password GeneratorGenerate strong, random passwords with crypto-secure randomness. Nothing leaves your browser.UUID GeneratorGenerate random UUID v4 identifiers in your browser.

Output in hex or Base64 — computed entirely in your browser.NanoID & ULID GeneratorGenerate cryptographically random NanoIDs (21 URL-safe characters) and ULIDs (26 characters, time-sortable). Choose how many and copy each or all at once.UTM BuilderBuild properly encoded UTM campaign links with source, medium, campaign, term and content — in your browser.Open Graph PreviewPreview your social share card and generate Open Graph and Twitter Card meta tags from your own values — in your browser.Barcode GeneratorGenerate barcodes in CODE128, EAN-13, UPC, CODE39 or ITF-14 formats.
