Free Online Tools for Business, Marketing & Developers
Most everyday digital tasks don't need a dedicated app or a paid subscription — they just need a tool that works quickly, without friction. Fenbrix built this collection of free online tools to cover exactly that gap: generating a QR code for a flyer, checking a GST calculation before sending a quote, shrinking a photo before it's emailed, tidying up a JSON response, building a WhatsApp link for a landing page, or generating a password that won't get guessed. Each tool runs entirely in your browser, so there is nothing to install, no account to create, and no waiting on a server somewhere else to process your request.
Business & Marketing Tools
Small business owners and marketers juggle a lot of small, repetitive tasks — pricing a quote correctly, sharing a WhatsApp number customers can message with one tap, or putting a QR code on a poster that links straight to a menu or offer. The GST Calculator handles both adding and removing GST at the standard Indian rates — 5%, 12%, 18% or 28% — or a custom percentage, useful when a quoted price needs to be broken down for a customer or checked against an invoice. The WhatsApp Link Generator turns a phone number and a message into a single shareable link for websites, Instagram bios and printed materials, and the QR Code Generator complements both by turning any link into a scannable code for offline marketing.
Developer Tools
Developers spend a surprising amount of time reformatting data by hand. The JSON Formatter & Validator turns minified API responses or config files into readable, indented JSON, or compresses readable JSON back down for production use — and when something is broken, it points to the exact position where parsing failed instead of a vague error. The Password Generator is also useful for setting up test accounts, API keys or temporary credentials that need to be genuinely random rather than typed out by hand.
Browser-Based Utility Tools
Some tasks are simple in principle but awkward in practice — like compressing a photo before uploading it somewhere with a strict file-size limit, or generating a password that isn't a variation of one you've used before. The Image Compressor reduces JPG, PNG and WebP file sizes directly in your browser using the Canvas API, so the image itself is never uploaded anywhere before you choose to send it. The Password Generator uses the Web Crypto API to produce genuinely random passwords, with control over length and character types. Both are built the same way as every tool on this page: fast to open, free to use, and designed to run locally rather than depend on a server round-trip for something that doesn't need one.
If your business needs something more involved than a free utility — a proper website, an internal tool or an automated workflow — that is exactly the kind of work Fenbrix builds day to day. Take a look at our services or get in touch to talk through what you need.
