4. **Download** — Download the result that met the target or the smallest readable output.

## FAQ

### 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.
