💾 Save Image Extended for ComfyUI

Save as JXL, AVIF, WebP, JPEG, JPEG2k, customize the folder, sub-folders, and filenames of your images!

Supports those extensions: JXL AVIF WebP jpg jpeg j2k jp2 png gif tiff bmp

• Customize the folder, sub-folders, and filenames of your images!
• Save data about the generated job (sampler, prompts, models) as entries in a json (text) file, in each folder.
• Use the values of ANY node's widget, by simply adding its badge number in the form id.widget_name
• Warning: ComfyUI can only load prompts from PNG and WebP atm

Parameters / Usage

Attribute	Description
filename_prefix	Fixed string prefixed to file name.
filename_keys	Comma separated string with sampler parameters to add to filename. E.g: sampler_name, scheduler, cfg, denoise Added to filename in written order. resolution also works. vae_name model_name (upscale model), ckpt_name (checkpoint) are others that should work. Here you can try any parameter name of any node. As long as the parameter has the same variable name defined in the prompt object, they should work. The same applies to foldername_keys.
foldername_prefix	Fixed string prefixed to subfolders.
foldername_keys	Same rules as for filename_keys. Create subfolders by using / or ../ etc.
delimiter	now a free field Delimiter = any string you like. You can also use / to create subfolders.
save_job_data	Saves information about each job as entries in a jobs.json text file, inside the generated subfolder. Multiple options for its content: prompt, basic data, sampler settings, loaded models.
job_data_per_image	Saves individual job data file per image.
job_custom_text	Custom string to save along with the job data.
save_metadata	Saves metadata into the image.
counter_digits	Number of digits used for the image counter. 3 = image_001.png, based on highest number in the subfolder, ignores gaps. Can be disabled when == 0.
counter_position	Image counter postition: image_001.png or 001_image.png.
one_counter_per_folder	Toggles one counter per subfolder, or resets when a parameter/prompt changes.
image_preview	Turns the image preview on and off.
output_ext	File extension: WEBP by default, AVIF, PNG, JXL, JPG, etc.
quality	Quality for JPEG/JXL/WebP/AVIF/J2K formats; Quality is relative to each format. Example: AVIF 60 is same quality as WebP 90.
named_keys	Prefix each value by its key name. Example: prefix-seed=123456-width=1024-cfg=5.0-0001.avif

• Unknown key names in filename_keys and foldername_keys are treated as fixed strings
  • if you enter wrongNumber.attribute, you will get attribute in your filename.
• Datetime UNIX format is now included! %Y-%m-%d or %F etc: see unix datetime formats
• default it output only the name for ckpt_name / control_net_name / lora_name not the path
  • use ckpt_path / control_net_path / lora_path to get the same subfolders as your models
• using .custom_string will prevent appending delimiter, the dot will be the delimiter

Examples

• prefix = PREFIX

• filename = cfg, sampler_name, /steps, %F %H-%M-%S

• foldername = ckpt_name/, .cfg

  • v1-5-pruned.cfg / PREFIX-8.0-euler / 20-2024-12-18 23-17-17-0001.png

• prefix = PREFIX

• filename = cfg, sampler_name, steps, %F %H-%M-%S

• foldername = ckpt_name, /, cfg

  • v1-5-pruned / 8.0 / PREFIX-cfg-8.0-euler-20-2024-12-18 23-21-41-0001.png

• prefix = PREFIX

• filename = "cfg", cfg

• foldername = ckpt_name, /, cfg

  • v1-5-pruned / 8.0 / PREFIX-cfg-8.0-0002.png

Node inputs

• images - The generated images.

Optional:

• positive_text_opt - Optional string saved as positive_text_opt in job.json when save_job_data=True.
• negative_text_opt - Optional string saved as negative_text_opt in job.json when save_job_data=True.

Automatic date/time conversion in file/folder names

Converts unix datetime formats:

Unix datetime	Example	Comment
%F or %Y-%m-%d	2024-05-22
%D	05/22/24	This effectively creates subfolders
%F %H-%M-%S	2024-05-22 09-13-58
%Y/%V	2024/21	year subfolder / ISO week number subfolder

Installation

Requirements:

There is a requirements.txt that will take care of that, but just in case:

• python 10.6
• piexif
• imagecodecs
• pillow
• pillow-avif-plugin
• pillow-jxl-plugin

pip install piexif pillow pillow-avif-plugin

For Jpeg XL / jxl it's more complicated. You cannot compile the wheel jxlpy on Windows. Therefore, we use an alternative: imagecodecs

pip install -U imagecodecs

Manual Download

1. Open a terminal inside the 'custom_nodes' folder located in your ComfyUI installation dir
2. Use the git clone command to clone the save-image-extended-comfyui repo under ComfyUI\custom_nodes\

git clone https://github.com/audioscavenger/save-image-extended-comfyui

Miscelaneous

JPEG XL is a heated debate on chromium forum and if true indeed that Google is working on WebP2, jxl is unlikely to take off any day soon. Proponents arguably declare with no proof, that jxl is better and faster than the current best codec: AVIF. But again, without support from the industry, it's going nowhere.

I tested with compression 90 and it's good, with a caveat. The compression offered by pillow is 3x lower then Image Magick for the same level. No idea why.

Pillow cannot save Exif data in JPEG2000, nor can it compress it in any way. Who the heck is using JPEG2000 in 2024 anyway?

Disclaimer: Does not check for illegal characters entered in file or folder names. May not be compatible with every other custom node, depending on changes in the prompt object. Tested and working with default samplers, Efficiency nodes, UltimateSDUpscale, ComfyRoll, composer, NegiTools, and 45 other nodes.

Quality and compression settings: default is 90, 100 will activate lossless for AVIF and WEBP only.

Quick comparison of size per extension, for the same 512x512 picture, with similar visual quality:

Ext	Compression	Maker	Size	Compression
png	max 9	PIL	413111	0%
j2k	n/a	PIL	395028	4%
jxl	lossless	PIL	301310	27%
jxl	90	PIL	179210	57%
jpeg	90	PIL	88554	79%
avif	90	Imagick	67272	84%
webp	90	Imagick	64416	84%
webp	90	PIL	64356	84%
avif	60	PIL	47353	89%
avif	60	Imagick	33691	92%

About extensions WebP AVIF JPEG JXL: ComfyUI can only load PNG and WebP atm... Feel free to ask ComfyUI team to add support for AVIF/jpeg/JXL!

The metadata Are included under the EXIF tags IFD below, as defined here WAS Node Suite also use those tags. They must be next to each other in order to Comfy to be able to load them with drag and drop.

Data	EXIF	Name	String looks like
prompt	0x010f	Make	Prompt: {"5" ... }
workflow	0x010e	ImageDescription	Workflow: {"5" ... }

You can retrieve the prompt manually with exiftool, here are some example commands:

• exiftool -Parameters -Prompt -Workflow image.png
• exiftool -Parameters -UserComment -ImageDescription image.{jpg|jpeg|webp|avif|jxl}

ComfyUI cannot load lossless WebP atm. Feel free to try and fix pnginfo.js

Incompatible with extended-saveimage-comfyui - This node can be safely discarded, as it only offers WebP output. My node already adds JPEG and WebP.

You asked for it... Now you can select which node to get the widget values from! Formerly, this custom node would simply return the last value found: useless if you have multiple same nodes... To see node numbers in the UI, enable the badge IDs:

Happy saving!

RoadMap

Reboot by AudioscavengeR since 2024-05-05, original idea from @thedyze

I won't promise you the moon, but since I use this node myself, I will maintain it as much as I can. I do provide a way to contact me, and will accept PR and collabs. Once I feel like I don't have time to work on it, I will gladly transfer ownership or let collabs maintain it.

TODO:

• accept multiple images as input
• improve get_latest_counter: restarts when user renames files after the counter part.
• offer to place the counter anywhere, as a key in filename_keys
• keep same counter if extension changes?
• files will be out of order if prefixes change... that is expected, but is this what we want?
• PIL.Image doesn ot respect compress_level value and always output max 9 compressed images.
• TODO: test import cv2 / OpenCV: python-pillow/Pillow#5986 -> not faster then PIL
