Are my PDFs uploaded?: No. Every target-size attempt runs in your browser.
What happens if the target is impossible?: The tool explains that the limit could not be reached and still gives you the smallest readable result it achieved.
Can a tiny target affect readability?: Yes. Very small limits may require lower DPI page-image compression, so the page warns when text may stop being selectable.
