Generators

Create scannable codes and test tones directly in your browser.

Start with the system that must receive the result: a phone camera, a barcode scanner or an audio playback chain. Generate locally, export only what you need and test in the real setting before relying on it.

Play precise frequencies and waveforms using your browser audio engine.

Open tool

Choose with confidence

Choose a generator by what must read the result

QR code for links and readable text

Use a QR code when a phone camera should open a URL, contact action or short text payload.

Barcode for inventory and retail systems

Choose Code 128, UPC, EAN or ITF only when the receiving scanner and database expect that symbology.

Tone for controlled audio checks

Generate a frequency and waveform for pitch comparisons or informal playback troubleshooting at a low volume.

A reliable workflow

From source to checked result

  1. 1

    Define the receiver

    Confirm the scanner, phone, software or speaker that will consume the output and any format it requires.

  2. 2

    Generate a conservative first version

    Use strong contrast for codes, the correct identifier standard for barcodes and low volume for audio.

  3. 3

    Test the final context

    Scan the printed proof or listen through the actual playback chain. A browser preview cannot reproduce every production condition.
