I’ve built a set of handy plugins for Sketch
Convert bitmap images into monochrome vector graphics.
Reset Image Aspect Ratio
Reset the aspect ratio of selected images.
Format Symbol Names
Nicely format the names of all artboards or symbol masters on the current page.
Size layers to common photo dimensions and scale them to fit in rows or columns.
A plugin to help you rename symbols. Save default values, use override text, and do powerful, pattern-based renaming.
Unlink symbols linked to a specific library, or that have been deleted in their libraries.
Copy Framer Code
Copy layers from Sketch as code that can be pasted straight into a Framer prototype.
