Questions

Can I compress many images at once?

Yes. Add a whole batch. If one image fails, the rest still finish.

Are my photos uploaded?

No. Toolbox is a desktop app, so it reads and writes the file on your own computer. It never uploads your files.

Does it change the original images?

No. Toolbox saves a new file beside the original and never overwrites it.
