Flattening a PDF merges all document elements into the background. This makes it impossible for others to edit form fields, checkmarks, or annotations. It's ideal for final submissions of contracts and medical forms.

Frequently Asked Questions

Will the text still be selectable?▾

Flattening renders pages as high-quality images, so text will no longer be selectable. This ensures maximum security against edits.
