Flattening makes form fields permanently non-editable. Keep a copy of the original if you may need to edit the form again later.
Lock in Your Data
When you fill out an interactive tax form or add sticky notes to a document, those elements sit on a separate, editable 'layer' on top of the actual page. If you email that file, the recipient can easily click on your checkboxes or delete your signature. To prevent this, you must flatten PDF files before sharing them.
Our tool merges all interactive layers—form fields, checkboxes, dropdown menus, and annotations—directly into the base image of the page. Once you flatten PDF forms, the data becomes permanent text. It prints perfectly, displays consistently across all devices, and ensures nobody can subtly change the numbers you filled in.
Flattening is especially important for financial and legal documents. Because we respect your privacy, our tool flattens your files entirely within your web browser. The sensitive information you typed into those forms is never uploaded to any external server.
