Questions
Which image formats can this compress?
It supports JPG, JPEG, PNG, and WebP still images. The tool detects the input format automatically and can keep the same format or export JPG, PNG, or WebP.
Why is there no separate JPG compressor tool?
Utilumo uses one high-quality image compression engine. Format-specific landing pages reuse the same engine for JPG, PNG, and WebP search intent without duplicating the tool.
How does ZIP download work?
When multiple images are ready, Utilumo packages the locally generated files into one ZIP in your browser so you can download them together.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
