💾 Save Image Extended for ComfyUI

Supports those extensions: AVIF WebP JXL jpg jpeg 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
• Promt saved in jpeg and AVIF, but ComfyUI can only load PNG and WebP atm

Parameters / Usage

Attribute	Description
filename_prefix	String prefix added to files.
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	String prefix added to folders.
foldername_keys	Comma separated string with sampler parameters to add to foldername. Add more subfolders by prepending "./" to the key name.
delimiter	now a free field Delimiter = 1 character, can be anything your file system supports. Windows users should still use "/" for subfolders.
save_job_data	If enabled, saves information about each job as entries in a jobs.json text file, inside the generated folder. Mulitple options for saving prompt, basic data, sampler settings, loaded models.
job_data_per_image	When enabled, saves individual job data files for each image.
job_custom_text	Custom string to save along with the job data. Right click the node and convert to input to connect with another node.
save_metadata	Saves metadata into the image.
counter_digits	Number of digits used for the image counter. 3 = image_001.png. Will adjust the counter if files are deleted. Looks for the highest number in the folder, does not fill gaps.
counter_position	Image counter first or last in the filename.
one_counter_per_folder	Toggles the counter. Either one counter per folder, or resets when a parameter/prompt changes.
image_preview	Turns the image preview on and off.
output_ext	File extension: PNG by default, or WEBP (coming soon).

Unknown key names in filename_keys and foldername_keys are treated as custom 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

Node inputs

• images - The generated images.

Optional:

• positive_text_opt - Optional string input for when using custom nodes for positive prompt text.
• negative_text_opt - Optional string input for when using custom nodes for negative prompt text.

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
• pillow
• pillow-avif-plugin

pip install piexif pillow pillow-avif-plugin

For Jpeg XL / jxl it's more complicated. You need to install and compile the wheel jxlpy, and therefore, need a valid and functional MSVC installation.

pip install jxlpy

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

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 75, 100 will activate lossless for AVIF and WEBP only.

Quick comparison of size per extension, for the same picture, AVIF quality=60, WebP quality=75, jpeg quality=91 (and yes, AVIF still looks better then WebP):

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 IFD0 as defined here

Data	EXIF	Name	String looks like
prompt	0x9286	UserComment	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:

jobs.json sample: always generated and appended, not sure what it can be used for.

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:

• ComfyRoll CR XY Save Grid Image: it offers jpeg webp tif - check how it embeds prompt and see if that works better with Comfy!
• offer quality setting in the node?
• remove save_job_to_json? thisis pretty much useless actually, since it only saves the last value found for each node.
• remove job_custom_text? what is this for?
• remove jobs.json? jobs history, alright. What do you do with that? images contain the prompt, what is this for?
• improve get_latest_counter: fails when user renames files: appends text after counter
• offer to place the counter anywhere, as a key in filename_keys
• files can get out of order if prefixes change... that is expected, but is this what we want? another reason to have the counter place anywhere we want

release 2.62 💾

• prompt and workflow are saved in IFD 270 and 271 for better load compatibility
• disabled jobs.json by default, this thingy seems useless to me

release 2.61 💾

• added quality input

release 2.60 💾

• added extensions jpeg, gif, tiff, bmp
• added image_optimization (only for jpeg)
• now saves prompt and workflow separately into 0x9286/UserComment and 0x010e/ImageDescription

release 2.51 💾

• added unix datetime formats

release 2.50 💾

• added JXL support
• added 'BOOLEAN' support

release 2.46 💾

• bug discovered with rgthree's Ksampler Config: using steps_total as an input to a Ksampler, will issue the index of the output, instead of the steps value ("[nodeNum, 0]" instead of steps value). FIX: use steps_total instead of steps!
• uncommented __all__ in init.py
• potential bugfix in splitKey, len(splitKey) = 2 to identify actual "node.widget" format

release 2.45 💾

• added 💾 in the name

release 2.44

• so many bugfixes
• complete rework of generate_custom_name to handle ALL the possible scenarios
• bugfix: when using /name in foldername_keys, Comfy thinks you want to save outside the output folder

release 2.43

• support for AVIF
• added requirements.txt

release 2.42

• fixed counter for variable file extensions length

release 2.41

• bugfix WebP encoding: Comfy could partially read the prompt, but the way they implemented it was buggy. PR fix submitted.
• WebP is indeed loaded properly like a PNG, if you apply the patch above to pnginfo.js and app.js`

release 2.4

• integrate webp
• integrate jpeg

release 2.3

• for each keys, we return only the last value found in the prompt. Not the last Ksampler. Impossible to know which one is the last. Therefore, simply use this syntax: number.widget_name
• filename_keys and foldername_keys become too large, switch to multiline
• also removes subfolders from values found, when people use subfolders like SD15/pytorch_blah.pt etc
• added what I was looking for the last 6 months in the first place: 123.attribute from nodes!
• limit delimiter to 1 char, or file counter will get too complex

release 2.2

• delimiter is now whatever you want, free field. Limited to 16 characters tho
• all is instance methods, previously we had @staticmethods. Why? Don't know.
• check get_latest_counter: does it still work with subfolders? yessir
• bugfix: custom_name was not updated for int and floats

release 2.1

• now accepts inexistant keys and use them as fixed strings
• now accepts inexistant keys with / and use them as subfolders

release 2.0

• Reboot on 2024-05-05
