Free Online Generators

A hosted suite of six browser generators — create QR codes, build colour palettes, hash text or files, generate UUIDs, scan QR codes, and make strong passwords. No installs, no sign-up, results instantly.

Free

QR Code Generator

Turn any text, URL or message into a QR code as you type. Choose the size, colours and error-correction level, then download a crisp PNG or scalable SVG.

Open tool Free

QR Code Scanner

Decode a QR code with your device camera in real time, or upload a screenshot or photo. The decoded text appears instantly, with a clickable link for URLs.

Open tool Free

Password Generator

Generate strong, random passwords with cryptographically secure randomness. Set the length, pick character types, read the strength meter, and copy in one click.

Open tool Free

Color Palette Generator

Roll harmonious colour schemes in one click. Lock the colours you like, regenerate the rest, and export the palette as CSS variables, JSON or a HEX list.

Open tool Free

Hash Generator

Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 checksums of any text or file, right in your browser. Verify a download or match a published checksum.

Open tool Free

UUID Generator

Generate version 1, 3, 4 and 5 UUIDs one at a time or in batches of up to 100. Cryptographically random v4, time-based v1, and deterministic name-based v3 and v5.

How the Generators Work

Six focused tools, one consistent interface. Pick a generator, enter a value or grant camera access, and use the result instantly.

1

Pick a tool

Choose the QR Code Generator or Scanner, the Password Generator, the Color Palette Generator, the Hash Generator or the UUID Generator. Each one is a single page with one job.

2

Enter or scan

Type the text to encode, point your camera at a QR code or upload an image, or set your password length and options. Everything happens live, on your device, with nothing sent to a server.

3

Download or copy

Download your QR code as PNG or SVG, open or copy a decoded link, or copy your new password to the clipboard. The tools stay fast and private and keep working offline once loaded.

Frequently Asked Questions

What are the LK Forge Generators?
Generators is a free suite of six browser-based tools hosted on LK Forge: a QR Code Generator that turns any text or URL into a downloadable PNG or SVG, a QR Code Scanner that decodes codes from your camera or an uploaded image, a Password Generator that builds strong random passwords with the Web Crypto API, a Color Palette Generator that rolls harmonious colour schemes you can lock and export, a Hash Generator that computes MD5 and SHA checksums of text or files, and a UUID Generator for version 1, 3, 4 and 5 identifiers. Everything runs in your browser — nothing you encode, scan, hash or generate is uploaded or stored, and there is no sign-up. Every tool works fully offline once loaded; only the scanner's live camera mode needs camera permission.
Are the generators free and private?
Yes. Every tool in the suite is completely free with no account, no payment, and no usage cap. Because all of the work runs client-side in JavaScript, nothing you enter leaves your device — there are no server round-trips and nothing is logged. The QR Code Generator encodes your text locally, the QR Scanner reads camera frames or uploaded images entirely in the browser, the Password and UUID generators use the Web Crypto API, the Hash Generator hashes text or files on your device, and the Color Palette Generator computes colours locally. That makes the suite safe for sensitive links, files and credentials and fast enough to update the moment you type.
Do I need to install anything?
No. There is nothing to download and no extension to add. The generators work in any modern browser on desktop, tablet or mobile. Open a tool, enter a value or grant camera access, and use the result instantly. The QR Scanner's live camera mode needs you to allow camera access when prompted, but you can also scan a saved screenshot or photo with the upload option if you would rather not use the camera at all.
Which generator should I use?
Use the QR Code Generator to share a link or message as a scannable square, and the QR Code Scanner to read one you already have. Use the Password Generator when you create or rotate an account credential. Use the Color Palette Generator to design a coherent colour scheme and export it as CSS, JSON or HEX. Use the Hash Generator to verify a download against a published checksum or fingerprint data with MD5 or SHA. Use the UUID Generator when you need unique identifiers for database keys, API requests or files. Each tool is a single focused page that does one job well.
