Can I use outputs generated by your tools for commercial projects?
Yes. You own 100% of all output files, processed text, compressed images, converted documents, and code generated using TechbyJeel Tools. We claim zero copyright over your content.
Privacy & Security
Are my uploaded files and text data stored on your servers?
No. TechbyJeel Tools operates on a client-side browser processing architecture. Your files, images, PDFs, text, and code snippets are processed locally on your device using WebAssembly and HTML5 FileReader APIs. Nothing is uploaded to or saved on our web servers.
Is it safe to convert confidential or personal documents on TechbyJeel Tools?
Yes. Because file transformations occur entirely inside your browser's local sandbox memory, your confidential data never traverses the Internet to third-party servers.
What cookies does TechbyJeel Tools use?
We use a minimal set of essential cookies to remember UI preferences (like dark mode), Google Analytics for anonymized traffic metrics, and Google AdSense for unobtrusive advertising. Read our full Cookie Policy for details.
PDF & Image Utilities
What is the maximum file size limit for image compression and PDF operations?
Because operations run locally on your device, file size limits depend on your device's memory. Most modern laptops and smartphones easily handle PDFs up to 200MB and high-resolution images up to 50MB.
How does image compression work without losing visual quality?
Our Image Compressor uses smart lossy and lossless algorithms in WebAssembly to strip unnecessary metadata, optimize color palettes, and compress pixel data while preserving visual fidelity.
Can I convert multiple images to PDF at once?
Yes. Our Image to PDF Converter supports multi-file upload, drag-and-drop reordering, page margin customization, and batch conversion into a single downloadable PDF.
Developer & Code Tools
Which programming languages and data formats are supported?
We provide dedicated formatters, validators, and converters for JSON, XML, YAML, HTML, CSS, JavaScript, SQL, Markdown, Base64, and JWT tokens.
Is my JSON or JWT token data sent to a backend server when decoding?
No. All JSON validation, formatting, JWT token decoding, and Base64 string processing execute 100% locally in your browser session. Your API keys and tokens remain private.
Can I format minified JSON or XML data?
Yes. Our formatters automatically beautify and indent minified code structures with customizable indentation levels (2 spaces, 4 spaces, or tabs).
Calculators & Financial Tools
How accurate are your financial and loan EMI calculators?
Our financial calculators use standard compounding and amortization formulas. While they provide highly precise estimates for planning, actual bank rates, taxes, and fees may vary.
Do you offer unit converters for physics, math, and measurement?
Yes. We offer comprehensive unit converters for length, mass, temperature, area, volume, speed, digital storage, and time conversions.

Comprehensive Guide to TechbyJeel Tools Suite & Features
TechbyJeel Tools was engineered to empower developers, content creators, business professionals, students, and digital marketers with high-performance, privacy-first web utilities. Traditional online converter and tool websites often require uploading your confidential documents, image files, or source code to third-party web servers, exposing your data to server logging and privacy risks.
By leveraging cutting-edge web technologies like HTML5 FileReader, Canvas API, WebAssembly (WASM), and Web Crypto APIs, TechbyJeel Tools executes complex file transformations, mathematical calculations, and code formatting directly inside your client web browser memory.
