You should purchase Lightroom Presets if you own Lightroom on your desktop/laptop (Windows/Mac only).
You should purchase Mobile Presets if you do NOT own Lightroom CC. All presets can by synced to mobile via Lightroom CC 1.4+, therefore we sell Mobile Presets for those that do not own Lightroom and wish to only use the free mobile app and/or can not sync via Lightroom CC because they only own a lower version of Lightroom.
You should NOT purchase XMP presets (always noted in the description) if you do NOT own Lightroom Classic 7.3+ or CC 1.3+. These will not work in lower versions.
If you own Lightroom Classic 7.3+ or CC 1.3+, then you can import both versions presets (lrtemplate format and the newer XMP format).
You should purchase Photoshop Actions only if you own Photoshop CC. These will not work in versions below CC.
All presets in XMP format will import into Photoshop ACR.
AI presets are only available in XMP format. They work best with the most recent versions of Lightroom Classic, Lightroom CC and/or Photoshop ACR. They require Lightroom CC 6.0, Lightroom Classic 11.4+ and/or Photoshop 24.1+ with Camera Raw 15.3+.
