Bring many frames to one palette, then clean up, audit and export in one place.

Implementation and verified quality

advanced · shared Oklab histogram / locked palette indices / ordered and error-diffusion dithers / indexed recolour. Quality qualification is in progress. Pro/Flagship quality has not been established.

Before you export

It prepares pixels; it does not draw new detail. Error-diffusion dithering can differ between frames, so animations should use None or an ordered matrix.

Are my files uploaded?

Nerulio processes selected files on your device and has no file-upload API. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.

Will my work be saved automatically?

No. Images and editing state stay in this tab; media output can use local temporary storage. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.
