Frequently asked questions

What does "flatten" mean here?

Every page is rasterized into a high-quality image and rebuilt as a new PDF, so text, form fields, and layers can no longer be selected or edited.

Why would I flatten a PDF?

To lock in the exact visual appearance before sharing — useful for filled-in forms or documents you don't want edited or have text copied from.

Does this upload my file?

No. Flattening runs entirely in your browser using client-side JavaScript.
