Questions
How much smaller will my PDF get?
It depends on the file. Toolbox compresses the PDF stream data. Files that are already compressed may shrink very little.
Can I compress several PDFs at once?
Yes. Add as many PDFs as you like. If one file fails, the others still finish.
Is my PDF uploaded?
No. Toolbox is a desktop app, so it reads and writes the file on your own computer. It never uploads your files.
