Privacy & Trust
Your files stay on your device
How Codrenix Toolbox actually handles your data — no vague promises.
Processed in your browser
Every tool available today runs entirely in your browser using client-side JavaScript. PDFs are merged, split, compressed and converted with in-browser libraries; images are resized and converted on canvas; QR codes and passwords are generated locally. Nothing about your file is transmitted to us.
Files are never stored
Files you open are read into your browser's memory, processed on your device and saved back by you. We have no upload pipeline and no file storage anywhere — close the tab and everything is gone. Text you type into a tool is saved only your own browser's local storage, never on a server.
No account required
There is no sign-up, no login and no email address needed for any tool — so there is no profile for us to sell, track or leak. If we ever add a feature that needs server processing, that specific tool page will state it clearly before you use it.

FAQ
Frequently Asked Questions
Is this really free?
Yes. Every tool on Codrenix Toolbox is completely free to use — there are no subscriptions, no one-time payments, no watermarks on output and no daily usage caps. The site is supported by ads, which is what keeps the tools free.
Do I need to create an account?
No. There is no sign-up, no login and no email required for any tool. Open a tool page and start using it immediately.
Is my data safe? Are my files uploaded anywhere?
Every tool available today runs entirely in your browser using client-side JavaScript — including the PDF tools, image tools, QR generator and password generator. Files you open are processed on your own device and are never uploaded to, stored on, or shared through our servers. When you close or refresh the tab, they're gone. If we ever add a tool that works differently, that tool's page will say so explicitly.
What kinds of tools do you offer?
Three categories: PDF Tools (merge, split, compress, rotate, protect/unlock, OCR, Word conversions), Image Tools (resize, compress, convert between JPG/PNG/WebP), and Utility Tools (QR code generator, password generator, unit converter). Browse the full list on the All Tools page.
Are there any limits on how many files I can process?
No daily limits or quotas. Because processing happens on your device, the practical limit is simply your browser's memory — very large files may be slower to process than small ones.
Does it work on my phone or tablet?
Yes. The site and every tool are built mobile-first and work in modern browsers on Windows, macOS, Android and iOS. No app install needed.
Can you add a specific tool I need?
We're actively adding new tools. If there's something you'd like to see, use the 'Tell Codrenix' link at the bottom of the tools list to suggest it.
