Online generators eliminate the need for expensive software, design skills, or technical knowledge to create professional assets. A great generator provides sensible defaults, clear customisation options, instant preview, and high-quality output — without requiring an account, a subscription, or putting your data at risk.
DocsConverter's generators run entirely in your browser. This means your passwords are never transmitted anywhere, your receipt contents stay private, and your QR code data isn't stored on any server. For sensitive generators — especially password generation — this is a critical security property, not a minor feature.
All generated assets are available for immediate download in appropriate formats. QR codes are downloadable as PNG or SVG. Receipts as PDF. Email signatures as copyable HTML. This ensures outputs are immediately usable in real workflows without additional processing.
What is a QR code and how is it generated?
A QR code (Quick Response code) is a 2D barcode that stores information (URL, text, contact details) in a grid of black and white squares. Our generator uses the qrcode.js library to encode your content according to the ISO/IEC 18004 QR code standard, then renders it as a PNG or SVG image in your browser.
Is the password generator truly random?
Yes. Our password generator uses window.crypto.getRandomValues() — the browser's cryptographically secure random number generator — which derives entropy from your operating system's hardware sources. This is the same API used by banking and security applications.
Can I use generated receipts for legal/tax purposes?
Our Receipt Generator creates visually professional documents, but they are not official tax receipts unless you are the business that issues them. For accounting and tax purposes, receipts should be issued by the merchant using their official accounting system.
Are the generated Terms and Privacy Policy legally binding?
Our Terms & Privacy Generator creates template documents based on standard legal language. However, they are NOT a substitute for advice from a qualified attorney. Regulations vary by jurisdiction, and important details specific to your business may not be covered by generic templates.
What is the difference between PNG and SVG for QR codes?
PNG is a pixel-based format — fine for digital use but may appear blurry when printed at very large sizes. SVG is vector-based and scales infinitely without any loss of quality, making it the best choice for print materials like posters, banners, or product packaging.
