About Generator Tools

Our generator tools save you time on repetitive creation tasks that developers, designers, and marketers face every day. Whether you need a QR code for a product label, a UUID for a new database record, or a realistic-looking dataset for testing, you can generate it here in seconds.

The QR Code Generator supports URLs, plain text, email addresses, and Wi-Fi credentials. You can customise the size, colors, and error-correction level, then download the result as a PNG or SVG. The Barcode Generator supports Code128, EAN-13, and UPC-A formats — the industry standards for retail and logistics.

For developers and QA engineers, the Fake Data Generator creates realistic test data including names, email addresses, phone numbers, and postal addresses. The UUID Generator produces cryptographically random v4 UUIDs in bulk, supporting lowercase, uppercase, and no-dash formats.

Creative tools include the Color Palette Generator, which creates complementary, triadic, analogous, and monochromatic palettes from any seed color and exports them as CSS variables. The Lorem Ipsum Generator produces placeholder text by paragraphs, sentences, or words. All generators run client-side — nothing you create is stored on our servers.

Frequently Asked Questions

Can I download the generated output?

Yes. QR codes and barcodes can be downloaded as PNG or SVG files. UUIDs and fake data can be copied to the clipboard or downloaded as a text/CSV file.

What QR code format is generated?

QR codes are generated as standard ISO/IEC 18004 QR codes, readable by all modern smartphone cameras and QR scanning apps without any special software.

Are generated passwords or UUIDs stored anywhere?

No. All generated output — including passwords, UUIDs, and fake data — is created in your browser and never sent to or stored on any server.

How random are the generated UUIDs?

UUIDs are generated using the Web Crypto API's `crypto.getRandomValues()`, which is a cryptographically secure pseudorandom number generator (CSPRNG) suitable for production use.

Is it safe to use fake data generated here in tests?

Yes. The fake data is generated locally and is completely fictional. It follows realistic patterns for names, emails, and addresses but does not correspond to any real person.
