SR Infobiz offers a growing suite of free, privacy-first tools that run entirely in your browser. Whether you need to format JSON, generate QR codes, convert images, or hash a string, you can do it all without creating an account or uploading files to any server.
In this guide, we will walk through five of the most popular tools and show you exactly how to use each one in under two minutes.
JSON Formatter & Validator
Paste any JSON string into the input area and click Format. The tool will pretty-print your JSON with proper indentation and highlight any syntax errors inline. It is perfect for debugging API responses or cleaning up configuration files before committing them to version control.
Base64 Encoder / Decoder
Need to embed an image in a CSS file or decode a JWT payload? Switch between encode and decode mode, paste your content, and the result appears instantly. Everything stays in your browser tab — nothing is sent over the network.
QR Code Generator
Type any URL, Wi-Fi credential, or plain text and a QR code appears in real time. You can download it as a PNG ready for print or sharing. Adjust the size and error correction level to match your use case.
Hash Generator
Select MD5, SHA-1, SHA-256, or SHA-512, enter your input, and the hash is computed client-side using the Web Crypto API. Useful for verifying file integrity or storing passwords during development.
Word Counter
Paste any passage of text and instantly see word count, character count, sentence count, and estimated reading time. A handy companion when you are writing blog posts, social media copy, or SEO content with specific length requirements.
