Which flattening mode should I use?

Use form flattening when you only need field values made permanent. Use complete flattening when links, layers and selectable content must also be removed.

Will text remain selectable?

Yes in form-field mode. Complete flattening converts pages to images, so text is no longer selectable.

Is my document uploaded?

No. Both flattening modes run locally in your browser.

About the Flatten PDF

Flatten PDF offers two clearly separated workflows. Form flattening makes AcroForm values permanent while preserving selectable text and vector quality.
