When something's wrong
Guides
All guides →Why your 3D model prints at the wrong size
You slice a downloaded model and it lands on the plate as a speck, or fills the whole bed. Nothing is damaged. The file simply never said what its numbers meant.
GLB, STL or OBJ: which 3D format to use
Three formats cover almost everything, and they are not interchangeable — each one throws away what it was designed not to need.
How to send a PDF that's too big to email
An attachment that looks comfortably under the limit can still be rejected, and the reason is rarely the one people assume.
Your files stay yours.
Most KIVO tools process your files directly in your browser. They don't need to be uploaded to our servers — so they never leave your device.
Every tool page says plainly whether it runs locally or needs a server. Right now, every single one of the 144 tools runs locally.
Works without a connection
KIVO does its work in your browser, so once a tool has loaded it keeps working with the network off — on a plane, on a train, on hotel wifi that only pretends to exist.
Each tool's code is fetched the first time you open it. Open the ones you'll need before you lose signal, and they stay available.
Fast. Useful. Quiet.
Software doesn't need to get in your way.
