How this works
This runs the same compression on every image you add, one after another, and keeps going even if one file fails — a bad or unsupported file is skipped and reported separately rather than stopping the whole batch.
Common questions
What happens if one image in my batch fails to process?
It's skipped and listed as an error; every other file in the batch still gets processed and downloaded normally — one bad file doesn't block the rest.
Can I set a different quality for each image?
No — one compression setting applies to the whole batch. If you need different settings per image, compress them individually using the single-image Compress Image tool instead.
