Convert PSDX to 8BBR

To our knowledge, converting Adobe Photoshop Touch Documents directly to Adobe Photoshop Brushes (.psdx to .8bbr format) is not possible, even though both the .psdx and the .8bbr formats originate from Adobe Photoshop.

We are not aware of any third-party solutions capable of converting .psdx to .8bbr.

In a word, direct psdx to 8bbr conversion is not possible.
So don't expect any so-called psdx to 8bbr converter or psdx to 8bbr free online conversion tool available.
