Everything you need, nothing you don't
Outilo brings together the small utilities you reach for again and again — a password generator, a word counter, an image compressor, a color picker and more — in one fast, clean place. Each tool lives on its own page so it loads instantly and does exactly one job well.
We built Outilo around privacy. Most tools, including everything that touches your images, run entirely inside your browser, so your files and text never get uploaded to a server. That makes them faster and keeps your data yours. And every tool is completely free, with no account, no watermark and no nagging.
