FAQ

Questions about our free online tools

Common questions about LearnCodeToday's free tools - their features, privacy, and limitations.

Are all tools on LearnCodeToday really 100% free? ▼
Yes - every tool is completely free with no hidden fees, no premium tiers, no credit card, and no time limit. All 25+ tools will remain free.
Do I need to sign up or create an account? ▼
No. Every tool works instantly without any login, signup, email confirmation, or account. Open the tool, use it, done. There are no gated features.
Do the QR codes have a watermark or attribution? ▼
No. QR codes are generated completely clean - no watermark, no LearnCodeToday text, no attribution anywhere. They are yours to use for free, even commercially.
Is my data safe? Is anything sent to your servers? ▼
For JSON Formatter, Password Generator, Base64, Image Compressor, Image Resizer, and most other tools, processing happens in your browser using JavaScript. For tools that require fetching a URL, like Website Audit, only the URL is processed.
Can I use these tools on mobile without installing an app? ▼
Yes. Every tool is responsive and works in any mobile browser, including Safari on iPhone and Chrome on Android. No app download is needed.
How do I create a QR code that opens Google Maps? ▼
Open the QR Code Generator, select Location as the QR type, enter your latitude and longitude coordinates, and download. Scanning the generated QR opens Google Maps at those exact coordinates.
Can I generate a GST invoice for free without any software? ▼
Yes. The free Invoice Generator creates professional GST invoices with company details, client info, line items, GST rate, discounts, and a professional layout downloadable as PDF.
What is structured data schema and why do I need it? ▼
Structured data, or JSON-LD schema, tells Google what your content is: a business, article, FAQ, product, or event. Google can use it for enhanced search results such as FAQ dropdowns and rich snippets.
