SaveSVGNode - ComfyUI Built-in Node Documentation

Save SVG files on disk. This node takes SVG data as input and saves it to your output directory with optional metadata embedding. The node automatically handles file naming with counter suffixes and can embed workflow prompt information directly into the SVG file.

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.
