FAQ
Where do I find the watts and the rate?
Watts are on the device label or power brick (or measure with a plug meter). The rate is on your bill — divide the total by kWh used for the true all-in rate, which is usually higher than the headline supply price.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
