Not sure if this would be useful to anyone else, but I put together a really basic tool to read/delete EXIF and metadata from SD/ComfyUI images:
Shows model, LoRA, prompts, seed, sampler, steps, etc.
If a ComfyUI workflow is embedded in the image, you can view and download the JSON too.
It is 100% browser-side, nothing is uploaded or saved anywhere, works fast on both desktop and mobile.
I also got tired of how slow and bloated some online compressors were,
so I made a simple resize/compress tool too:
You can adjust resolution and compression ratio in real time and visually check the result before saving. Super useful when dealing with upscaled images that are too big for some sites.
Hope this helps!
