ToolSink

Utility

QR & barcodes, passwords, speech tools, invoice & resume builders, colour picker and everyday calculators.

Utility tools cover everyday jobs: QR and barcode graphics, strong password generation, age and fraction/average calculators, a colour picker, browser text-to-speech and speech-to-text, plus Invoice Generator and Resume Builder with PDF download.

Passwords, QR codes, invoices and resumes are produced locally in your browser. Speech tools use your device’s built-in voice APIs — audio is not sent to ToolSink servers.

Use QR/Barcode for scannable links, Password Generator for unique credentials, speech tools for hands-free reading or dictation, and Resume/Invoice when you need a polished PDF without installing office software.
