Generator — Complete Guide
This page collects the guides for 6 tools in one place. Pick a tool name from the list and its guide opens beside it, so there is no page to navigate to and no account to create.
QR Code Generator
Generate QR codes with size and error-correction control.
How to use it
- Type or paste the text or URL you want to encode.
- Run the generator to draw the QR code.
- Download the PNG and check it with a second phone camera before printing it.
Use cases
- Printing a table tent card where guests will scan with their own camera.
- Handing over a Wi-Fi password without writing it on a whiteboard.
- Labeling a physical item so an inventory scan finds the matching record.
Limitation — Creates QR codes with size and error-correction level; it is not a reader or logo-embedding designer.
CV Builder
Build a one column CV with real PDF text and a parser check.
How to use it
- Fill in the contact fields, then the experience and skills sections.
- Export the PDF.
- Check the parser result to confirm the fields landed on the page.
Use cases
- Producing an ATS-readable resume without a word processor.
- Checking that an exported PDF really contains the text you typed.
- Generating a plain, consistently formatted CV for a batch of applications.
Limitation — Exports PDF only, uses one plain column with no graphic template, and the parser check confirms the text can be read back rather than predicting how a specific employer system scores it.
Gradient Generator
Create CSS linear gradients from two colors.
How to use it
- Enter two hex colors, or pick them with the colour swatches.
- Drag the angle slider to the direction the gradient should run.
- Copy the CSS value, or copy it wrapped in a background declaration.
Use cases
- Writing a hero section or banner background without hand-tuning the angle.
- Reproducing a gradient from a design file so you can check the degree value.
- Checking how two brand colours blend at a specific direction.
Limitation — Creates two-color linear CSS gradients; it does not generate radial or multi-stop gradients.
Random File Generator
Generate random binary test files in a ZIP archive.
How to use it
- Set how many files to generate.
- Set the size of each file.
- Run it and download the ZIP.
Use cases
- Testing an upload limit or timeout without a real large file.
- Checking that a parser rejects malformed input without crashing.
- Measuring throughput on a sync or backup script.
Limitation — Generates random binary test files inside a ZIP, not realistic JPG, PDF, or office documents.
Favicon Generator
Generate favicon.ico from an image in your browser.
How to use it
- Choose a square source image — 256x256 or larger works best.
- Keep the default sizes (16, 32, 48) or add more up to 256.
- Generate and download favicon.ico, then place it at your site root.
Use cases
- Creating favicon.ico for a new website launch.
- Replacing an outdated favicon with a new brand logo.
- Generating a multi-size icon from a single design file.
Limitation — Generates a classic ICO container with BMP frames; it does not create PNG or SVG icons, and browsers choose the best size automatically.
Invoice Generator
Fill a short form and get a clean invoice or receipt PDF, ready to send. Runs in your browser.
How to use it
- Fill in your name, the client name, and the date. The invoice number is optional.
- Add one line per service or item, with the quantity and the unit price. Add tax or a discount if the job has one.
- Watch the document update next to the form as you type -- that is the page the client will see.
- Press Download PDF. The file is built in your browser, and your form is saved in the browser for the next invoice.
Limitation — Check the input and result before relying on this tool for important work.
All Loonix tools process your input in the browser: text you type and files you pick never leave your device. Anything downloaded from the internet — say the FFmpeg runtime — is a supporting binary, not your data.
