Frequently Asked Questions

Birhrt Dev Tools is a free, browser-based platform offering 26+ developer utilities. It includes tools for JSON formatting, PDF manipulation, cryptographic hashing, Base64 encoding/decoding, JWT token inspection, regex testing, SQL formatting, image compression, and more. Every tool runs entirely in your browser — no data is ever sent to external servers.

Our tools are designed for software engineers, web developers, DevOps professionals, data analysts, QA testers, and anyone who works with data formats, encoding, or document processing. Whether you are debugging an API response, verifying file checksums, or preparing PDF documents, these tools are built for your daily workflow.

Yes, all tools are completely free with no usage limits. There are no premium tiers, no hidden fees, and no account required. The platform is supported by advertisements via Google AdSense.

No. You can use every tool on the site without creating an account, providing an email, or signing up for anything. Just visit the tool page and start using it immediately.

Currently, Birhrt Dev Tools offers 26+ individual tools across categories including JSON & Data, PDF Processing, Encoding & Security, Text & Code, and General Utilities. We are continuously adding new tools based on developer feedback.

Yes. Every tool on Birhrt Dev Tools processes data locally in your web browser using standard Web APIs (Web Crypto API, Canvas API, FileReader API, etc.). Your files, text, tokens, and any other input never leave your device. There is no server-side processing, no data logging, and no data transmission.

No. We do not store, log, or transmit any data you input into our tools. Some tools may use your browser's localStorage to save preferences (like theme settings), but your actual tool inputs and outputs are never persisted unless you explicitly download or copy them.

Yes, it is safe to use sensitive data in our tools because all processing happens locally. However, we always recommend general security best practices: ensure your browser is up to date, be cautious with browser extensions that might intercept page content, and avoid using public or shared computers for sensitive data.

The site itself uses minimal cookies for theme preferences. However, Google AdSense (our advertising partner) may use cookies and web beacons for ad personalization. You can manage your ad preferences through Google's Ad Settings or opt out of personalized advertising.

We do not use any first-party analytics, tracking pixels, or telemetry. Google AdSense, as a third-party service, may collect certain anonymized data for ad serving purposes. Please refer to our Privacy Policy for complete details.

Our tools cover five main categories: (1) JSON & Data Tools — format, validate, compare, and convert JSON/CSV/YAML data; (2) PDF Tools — merge, split, convert, redact, and manage PDF documents; (3) Encoding & Security — hash generation, JWT decoding, Base64 encoding, UUID generation; (4) Text & Code — regex testing, SQL formatting, Markdown preview, CSS generation, cURL conversion; (5) Utilities — timestamp conversion, URL parsing, QR code generation, image compression, invoice creation.

There are no server-imposed file size limits since all processing happens in your browser. The practical limit depends on your device's available memory (RAM). Most modern browsers can comfortably handle files up to 50-100 MB. For very large files, we recommend using a desktop browser with sufficient memory.

Several tools support batch processing. For example, the PDF Organizer lets you upload and merge multiple PDFs, the Image to PDF converter accepts multiple images, and the UUID Generator can create thousands of IDs at once. Each tool's page describes its specific capabilities.

Each tool supports the most common and widely-used formats relevant to its function. For example, the Image Compressor supports JPEG, PNG, and WebP; the PDF tools work with standard PDF documents; and the JSON formatter handles any valid JSON. Check individual tool pages for specific format support.

Birhrt Dev Tools works on all modern web browsers including Google Chrome (v90+), Mozilla Firefox (v90+), Microsoft Edge (v90+), Safari (v14+), and Brave. We recommend using the latest version of your browser for the best experience and full API compatibility.

Yes, the interface is fully responsive and works on smartphones and tablets. However, tools that involve heavy file processing (PDF manipulation, image compression) may perform better on desktop browsers due to memory constraints on mobile devices.

Once a tool page is fully loaded in your browser, most tools will continue to function even if you lose your internet connection. The processing logic runs entirely on client-side JavaScript. You need an initial internet connection to load the page, but after that, no network requests are made for tool operations.

Since all processing happens in your browser, performance depends on your device's hardware. Complex operations on large files (like merging big PDFs or compressing high-resolution images) require sufficient RAM and CPU power. Try closing other browser tabs, using a desktop browser, or reducing the file size.

Yes, you can use all Birhrt Dev Tools for any personal, educational, or commercial purpose without restriction. The tools are free for all use cases. However, you may not redistribute or resell the tools themselves.

We welcome all feedback. Please email us at birhrt@zohomail.in with a description of the bug (including the tool name, browser, and steps to reproduce) or your feature request. We review all submissions and prioritize based on community demand.
