About Lumina
Lumina is a small collection of image tools built on a simple idea: editing a photo shouldn't require handing it to a stranger's server.
Privacy by architecture
There is no upload endpoint. Your images are decoded and edited on a canvas inside your own browser tab.
Instant by default
No queues, no round trips. Editing happens at the speed of your device, even offline once the page has loaded.
Free, forever
No accounts, no watermarks, no export limits. Every tool is fully usable the moment you land on it.
Our story
We kept running into the same problem: needing to shrink a screenshot or convert a photo, and the only options were sites that asked for an email, added a watermark, or quietly kept a copy. Modern browsers are more than capable of doing this work themselves, so we built the toolkit we wanted to use.
Today Lumina covers enhancing, compressing, resizing, converting, cropping, rotating and filtering — and we keep adding tools as people ask for them.
