About Codrenix Toolbox

Codrenix Toolbox is a collection of practical, no-nonsense online tools. We cover the everyday tasks people deal with constantly: handling PDFs that arrive in every shape and size, resizing and converting images, and small utilities like QR codes, password generation and unit conversion.

Everything here is free, runs quickly, and keeps your files private by processing them securely. We deliberately keep the design clean and functional — a toolbox should feel fast and reliable, not shiny.

Codrenix Toolbox is built and maintained by the team at Codrenix. Need a website for your own project? Visit codrenix.in.

How the tools work

Every tool available today runs entirely in your browser. When you open a PDF, an image or use a utility tool, the work happens on your own device using client-side JavaScript — nothing is uploaded to, stored on or shared through our servers. Close the tab and your data is gone. That's not just a privacy promise; it's also why the tools feel fast: there's no upload wait and no processing queue.

What you'll find here

Three categories cover the everyday essentials: PDF Tools (merge, split, compress, rotate, protect/unlock, OCR for scanned documents, and Word/JPG conversions), Image Tools (resize, compress and convert JPG/PNG/WebP), and Utility Tools (QR code generator, secure password generator and a unit converter). We add new tools regularly — suggestions are always welcome.

Our principles

• Free means free — no subscriptions, watermarks or locked features.
• No accounts — no sign-up wall between you and the tool.
• No daily limits — use the tools as often as you need.
• Your files never leave your device.
