Start with your task
Search for a word such as merge, photos or JSON, or open a category. Each tool explains what it changes and what to check. The ES/EN switch takes you to the equivalent page; language is not selected by location.
A download is missing
Check your downloads folder or browser notification. The result link stays available to download again until you change the input or reset. On mobile, your browser may open the file before offering Save or Share.
A file cannot be opened
Try a small unprotected copy. Check the format and limit stated in the tool. Corrupt files or insufficient memory may prevent processing; the message helps identify the issue.
Browser and connection
JavaScript and a modern browser are required. Tools use Canvas, Web Crypto and local PDF workers depending on the task. The page needs a connection to load its resources; after loading, processing does not send your content to the internet.
Copying a result
Allow clipboard access if the browser asks. If it fails, select the result and use your device’s Copy command. Text result fields are read-only but can be selected.
