How It Works Under the Hood
Invoice line totals, discounts, and taxes calculate reactively in TypeScript. Business sender info and payment instructions persist in localStorage on your device, and pdf-lib assembles a crisp A4 PDF locally without sending any financial data to a server.

Enter your business details, upload an optional logo, and customize accent color & currency.
Add your client information and itemized services or products.
Adjust discount, tax/VAT %, shipping, and payment terms.

- Auto-Saved Sender Profile: Business info and payment details stay remembered via localStorage

- 100% Client Privacy: Client names, rates, and bank instructions never leave your device
Local Browser Processing & Privacy
Traditional web converters upload your documents, snippets, or media files to remote servers. Zero-Signup Invoice Generator (Clean PDF) runs inside your browser tab:
Your input text and files are processed locally without uploading payloads to a processing server.
Microdeck does not log or store the files or inputs you paste into tool workspaces (normal static hosting/CDN requests still load page assets).
Working outputs stay in your browser tab and are released when you reset the tool or close the tab.
