Is my image uploaded?

No. Pixel processing runs on a canvas in your browser.

Which noise type looks like film?

Gaussian with monochrome enabled and a grain size of 1–2 gives the most film-like result.

Why add grain to a gradient?

A small amount of noise breaks up colour banding on 8-bit gradients, especially on dark backgrounds.

What format is the export?

PNG, so the added grain is preserved losslessly.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
