Pick a preset or build your own. It goes on every photo you dropped in. You get the batch back at full resolution, as JPEG or PNG.
Drop in the frames from a shoot. Choose a preset and it lands on all of them. Each photo still gets its own correction, because a bright frame and a dark frame need different numbers to arrive at the same place.
Then export. Every photo, full resolution, in one ZIP. iPhone HEIC opens straight off the camera roll. No converting first.
There is no upload. Decoding, grading and export all happen in your browser, on your machine. That is not a promise we are asking you to take on trust. The browser itself blocks this page from sending anything anywhere.
