Smaller PSD - Filesize Reduce Kit

Works with Photoshop CC 2015+

Smaller PSD offers a variety of helpful scripts and functions to reduce your PSDs filesize. It processes all layers, so you don’t have to select anything by hand. The panel can reduce/delete invisible layers and pixels, flatten or rasterize layers, apply masks, replace placeholder images with frames and more.
Please note: No script can “magically” reduce any PSDs filesize. The size can be reduces if your PSD has…

• …images which are only placeholders (- can be replaced by color or frame),
• …images which can be reduces in sharpness / detail,
• …layers which are obscured by other layers (hidden pixels),
• …layers with (pixel) masks,
• …layers with clipping masks (clipping layer must be larger than its base),
• …empty layers,
• …Smart Objects,
• …layers which stand out of the document bounds,
• …hidden or invisible layers (visibility, opacity, fillOpacity),
• …layer styles / effects which are hidden,
• …groups which can be merged,
• or your PSD doesnt need maximal compatibility (no thumbnail / preview in other software)

Most methods are lossy, which means the reduced data can’t be restored at a later point (unlike zipping). If your PSD will be handed to a client, you should consider how editable the PSD should remain, and which parts can be deleted.
Please note: For installation it's recommended to use one of the 3rd-party installers mentioned in the instructions.
Alternatively, you can also manually unzip the .zxp contents and move them to "C:Program Files (x86)Common FilesAdobeCEPextensions".
