questions.
Is my PDF uploaded?
No. The file is processed in your browser with the pdf-lib library and never sent to a server.
Should I use a fillable PDF or a web form?
Fillable PDFs suit documents people print or archive. A web form is easier on phones and delivers submissions straight to your inbox.
Is anything I enter saved or sent to Form Koi?
No. Everything you type or upload stays in this browser tab and is processed locally. Copy or download anything you want to keep before leaving the page.
