Useful limitations
The simple RGB inversion is not a film-negative color-profile restoration workflow. Browser decode support and color profiles vary, and local device memory limits apply. For animation, only one still frame is used.
Privacy and compatibility
The selected file is read locally with browser APIs. It is not sent to this website’s server. Outputs are generated locally; some exports become PNG, text/JSON or single-page PDF according to the tool. Keep an unedited original and check the result carefully.
