PSDETCH
PSDETCH is a completely free tool which works both online and offline to make designers and developers working more closely and easily. It allows designers focusing more on designing and developers easily extracting information needed from design files directly. Developers can extract layers from design files to different format (jpg, png, svg etc), get layer measurement or get CSS information for some specific layers. PSDETCH also helps team collaboration by connecting to team's Cloud Provider e.g. Google Drive / One Drive / Dropbox etc. Collaborators can easily add comments / discuss on the same design file and switch among revisions to see the difference.
