Remove the seed input parameter and automatically resolve the seed value from the first KSampler node in the workflow prompt. Supports following link chains for connected seed inputs (Seed (rgthree), ImpactInt, etc).

Why this node exists
ComfyUI's built-in SaveImage dumps all files flat into the output directory — no global sequence numbers, so batch-generated files don't always sort in generation order. Stable Diffusion WebUI organizes images by date automatically, making browsing much easier.
Let's be honest: I'm just used to WebUI and don't want to leave my comfort zone.
This node brings WebUI's date-based directory structure and global sequence numbering to ComfyUI while preserving ComfyUI's workflow metadata embedding (PngInfo for PNG, EXIF for WebP), and adds a prefix parameter for custom subdirectories and filename prefixes.
Usage
Replace the built-in SaveImage node — no extra wiring needed. The seed is automatically resolved from the first KSampler node in the workflow.
Parameters
| Parameter | Description |
|---|---|
images |
Images to save |
filename_prefix |
Controls both subdirectory and filename prefix, see rules below |
image_format |
Save format: png / jpg / webp |
quality |
Compression quality for jpg and webp (0-100), ignored for png |
Seed: Automatically read from the first KSampler node in the workflow and embedded in the filename (e.g.
00001-12345.webp) for easy cross-reference with generation settings. Defaults to 0 if no KSampler is found.
Prefix rules
A date folder yyyy-mm-dd is always the direct parent of the file. Prefix paths nest above the date folder.
| prefix | Output path |
|---|---|
txt2img/ |
output/txt2img/2026-05-25/00001-seed.webp |
abc |
output/2026-05-25/abc00001-seed.webp |
imgEdit/qwen |
output/imgEdit/2026-05-25/qwen00001-seed.webp |
"" |
output/2026-05-25/00001-seed.webp |
abc/def/ |
output/abc/def/2026-05-25/00001-seed.webp |
abc/def/114514 |
output/abc/def/2026-05-25/11451400001-seed.webp |
Rules:
- Ends with
/→ directory only, no filename prefix - No
/→ filename prefix only, no subdirectory - Contains
/in the middle → everything before the last/is directory, after is filename prefix
Metadata embedding
- PNG: prompt and workflow written via PngInfo
- WebP: prompt and workflow written via EXIF (Make/ImageDescription tags)
- JPG: no metadata support
