The summary under the title lists the input type, whether one or several files are needed, and any settings. Fill in the settings, add your file, and press Run tool. Tools with no input file create their output from the settings alone.
No. The tool runs in your browser, and your files stay on your device. PDF and ZIP tools load their helper library the first time they run, so they need an internet connection at that point.
Files over 10 MB are skipped, and the message names them. The file picker also shows only the types this tool accepts, so pick a file of a matching type.
Tools that accept several files let you add more with each drop or choice. For a single-file tool, a new file replaces the one already selected. Use the × next to a file to remove it.
Each result has its own Download button. When a tool produces several results, Download all as ZIP saves them together in one archive.
The list under the tool shows up to six other tools. Tools from the same category come first, followed by tools that accept the same file types.
Check the settings you entered and try the original file again. Keep a copy of your original file, and check important output before you rely on it. See the disclaimer for more.
