What Onsilio is
Onsilio is a workspace of micro-tools: small, single-purpose tools for the tasks that come up around the real work. Each one does one thing, and nothing more, so the page you land on is already the tool.
Every tool has its own page that says what it does, what it accepts and what happens to your file, so it is easy to bookmark, share or come back to. Most tools work in your browser; a few send your file to us and return the result on the same page. Nothing to install, no account to open.
