A little less friction.

For the everyday edits

A picture too large to send. A thumbnail in the wrong shape. A folder of images that needs one consistent format. Luma brings those small tasks into a single, straightforward place.

Your browser does the work

The image tools use your browser’s decoding and drawing capabilities. The video tools use open-source media libraries and a video engine that runs on your device. Your files are not uploaded for processing. There are no accounts, subscriptions or watermarks.

Clear about the tradeoffs

A local tool depends on your device. Files can be too large, a codec can be unavailable, and compression can make a picture worse. Luma shows these boundaries instead of promising unlimited capacity. Read the compatibility notes.
