MultiTools brings together 100 practical web tools for the tasks people do every day: preparing documents, optimizing images, writing to a word limit, debugging code and planning finances. Instead of installing a different app for each job, or uploading private files to sites full of pop-ups, you can open a single, fast website and finish the task in seconds.
Most of our tools run entirely inside your web browser. When you merge PDF files, convert JPG to PDF or compress an image, the work is done by your own device and the files are never sent to our servers. That makes the tools quicker, because there is nothing to upload or download, and it keeps confidential documents such as contracts, ID scans and payslips private.
Students use the word counter and PDF tools to meet assignment requirements. Office teams combine reports and shrink attachments so they fit in an email. Developers rely on the JSON formatter and password generator during daily work. Small business owners create QR codes for menus and flyers, and anyone planning a loan can check the monthly payment with the EMI calculator before talking to a bank.
Every tool is free to use without an account, without daily limits and without watermarks. We keep the lights on with a small number of clearly labelled ads. If you have an idea for a new tool, let us know. Many of our tools started as user requests.
