Extended Save Image for ComfyUI
This custom node is largely identical to the usual Save Image but allows saving images also in JPEG and WEBP formats, the latter with both lossless and lossy compression. Metadata is embedded in the images as usual, and the resulting images can be used to load a workflow.
Installation
To install, clone this repository into ComfyUI/custom_nodes
folder with git clone https://github.com/palant/extended-saveimage-comfyui
and restart ComfyUI.
