Frequently asked questions
Are my files uploaded?
No. The PDF is opened and changed inside your browser, so it never leaves your device. You can even switch off Wi-Fi after the page loads.
Which mode should I choose?
Strong turns each page into a compressed image, which shrinks scans a lot but makes text unselectable. Basic repacks the file and keeps everything editable, but saves less.
What if the file gets bigger?
Then you get your original back unchanged, and a note suggesting a lower setting.
