Raw media never leaves your browser context. All memory is released when you close the tab.

  1. Useful tools

    Laser-focused single-purpose utilities engineered to solve real feed-preparation headaches without bloat, forced memberships or subscription paywalls.

  2. Straightforward controls

  3. Careful image handling

    Pure client-side processing, so your high-resolution photographs never touch a remote server and keep their authentic colour profiles and sharpness.
