There is nothing to install and no account to create.
How the tools work
Every tool follows the same simple pattern: add your file, text or URL, choose an option if you need one, and get the result in a few seconds. File-based tools process your upload on our server and give you a download link, while text and calculator tools return the answer instantly on the page. Clear step-by-step instructions and short guides sit below each tool, so beginners and professionals can both get the job done quickly.
