SaveSVGNode - ComfyUI Built-in Node Documentation

Save SVG files on disk.

Save SVG files on disk. This node takes SVG data as input and writes it to the ComfyUI output directory, automatically handling file naming with counter suffixes. When workflow prompt information is available, it is embedded directly into the SVG file as a metadata element.

Inputs

Parameter	Description	Data Type	Required	Range
svg	The SVG data to be saved to disk	SVG	Yes	-
filename_prefix	The prefix for the file to save. This may include formatting information such as %date:yyyy-MM-dd% or %Empty Latent Image.width% to include values from nodes. (default: “svg/ComfyUI”)	STRING	Yes	-

Outputs

Output Name	Description	Data Type
svg	The original SVG data, passed through after saving	SVG
ui	Saved file information including filename, subfolder, and type for display in the ComfyUI interface	DICT

Note: This node automatically embeds workflow metadata (prompt and extra PNG information) into the SVG file when available. The metadata is inserted as a CDATA section within the SVG’s metadata element. Files are saved using the pattern filename_prefix_00001_.svg; when processing a batch, %batch_num% in the prefix is replaced with the index of the current batch item. The node is an output node, so it produces a saved result in the output folder even though the file itself is not displayed as an image preview.
