Welcome to the Krishna AI Studio Developer Toolkit — a curated collection of six essential utilities that every developer, designer, and content creator needs in their daily workflow. Every tool on this page runs entirely inside your browser using client-side JavaScript. That means your data never leaves your machine — no server calls, no uploads, no tracking. Whether you need to quickly format a messy JSON payload from an API response, encode sensitive strings to Base64 for authentication headers, generate a QR code for a marketing campaign, count words in your blog draft, produce Lorem Ipsum filler for a wireframe, or sanitize a URL with special characters, you can do it all here in seconds. Bookmark this page and stop juggling between a dozen different websites.
Paste your raw JSON data below to instantly beautify, format, and validate it. The tool parses your JSON, checks for syntax errors, and outputs a clean, indented version. Perfect for debugging API responses, configuration files, and data payloads.
Convert plain text to Base64 encoding or decode Base64 strings back to readable text. Commonly used for encoding binary data in URLs, email attachments, data URIs, and API authentication tokens (like HTTP Basic Auth headers).
Generate a high-quality QR code from any text, URL, email address, phone number, or Wi-Fi credentials. The QR code is rendered on an HTML canvas element right in your browser. You can download the generated image as a PNG file for print or digital use.

Paste any text to instantly see a detailed breakdown of word count, character count (with and without spaces), sentence count, paragraph count, and estimated reading time. Ideal for writers, bloggers, students, and social media managers who need to stay within character limits.
Generate placeholder Lorem Ipsum text for your design mockups, wireframes, and prototypes. Choose between paragraphs or sentences and specify the exact amount you need. The generated text uses the classic Cicero-based Lorem Ipsum corpus with natural variation.
Encode special characters in URLs to their percent-encoded equivalents, or decode percent-encoded URLs back to human-readable form. Essential for working with query strings, API parameters, redirect URLs, and any URL that contains spaces or special characters.
Generate highly secure random passwords or standard version 4 UUIDs (Universally Unique Identifiers) directly in your browser. All generation is done client-side using cryptographically secure random number generators (window.crypto), ensuring maximum security and privacy.
Common questions about our free developer toolkit.
encodeURI() function, which encodes special characters but preserves characters that are valid in a complete URL (such as :, /, ?, #, and &). The "Encode Component" button uses encodeURIComponent(), which encodes everything except letters, digits, and a few safe characters. Use "Encode Component" when you are encoding a value that will be placed inside a query parameter, and use "Encode URL" when encoding a complete URL string.
