About Compresso
Compresso is a small collection of free, privacy-first web tools that run entirely in your browser.
What we do
Compresso offers everyday utilities — an image compressor and converter, a PDF merger, and a sprite sheet slicer — that work without accounts, uploads, or installs. You open a page, drop in a file, and get your result in seconds.
Privacy by design
Every tool processes your files locally, using your own device. Nothing is uploaded to a server, so your images and documents never leave your computer. This is not just a promise — it is how the tools are built. It keeps your data private and makes the tools fast.
Why it exists
Compresso is built and maintained by an independent game developer. Advertising revenue from these tools helps fund that game development. Keeping the tools genuinely useful, fast, and free is what makes that possible, so improving them is in everyone's interest.
What's next
We are steadily adding more tools, with a focus on things creators and developers actually need. If a tool you rely on is missing, we would like to hear about it.
