Online Tools (tools.jbfactory.net) is a free collection of web tools for everyday jobs that are too small to justify installing software: editing PDFs, converting images, running calculations and working with text or code. Every tool runs in your browser without an account and is available in 12 languages.
There are currently 43 tools in six categories:
See the full tool list for every tool.
The image and PDF converters, calculators and code tools all run as JavaScript inside your browser. The files you select and the text you enter are not uploaded to a server, and they disappear when you close the page. That keeps the tools fast on any connection and makes them safe for sensitive documents.
The one exception is My IP Address: your public IP address can only be seen by a server, and the tool queries a third-party service (ip-api.com) to show an approximate location.
All tools are free, with no usage limits. The site is funded by the Google AdSense ads shown on its pages, and it collects anonymous statistics with Google Analytics to learn which tools people use. See the Privacy Policy for details.
The calculators and converters use published standard formulas and established open-source libraries (such as pdf-lib and pdf.js), and their results are checked against known inputs. Results are still for reference only: for important decisions about loans, health or legal matters, confirm with your bank or a qualified professional.
The site is built and maintained by JB FACTORY. Whenever a tool is added or fixed, all 12 language versions are updated together.
If a result looks wrong, a translation reads oddly, or there is a tool you need, email jb@jbfactory.net. Feedback goes straight into improving the tools.
