Workbox

Image submission, simplified

Make your imageready to submit.

Paste the upload requirements. Choose your image.
Workbox handles the rest.

  • Requirements parser

    We turn everyday wording into checks the browser can verify.

  • Image processor

    Format, file size, dimensions, and shape are handled for you.

  • Final-file validator

    The downloaded result is read again before we call it ready.

  • Private by default

    Your image stays on your device throughout the process.

Tell us the requirements

Paste the wording from the website, form, or application.

Upload your file

Processed on your device. Your file stays private.

How it works

You provide the requirement. Workbox proves the result.

  1. 1

    Tell us what the form asks for

    Use the same words you were given. No image jargon needed.

  2. 2

    Choose your image

    The browser checks and prepares it locally, without an upload.

  3. 3

    Download only after it passes

    Workbox reopens the final file and validates its real properties.

Privacy first

Your file never needs to leave your device.

Processing happens in your browser. Analytics receives only broad technical categories—not filenames, requirement text, image contents, or photo metadata.

  • No account
