Så här fungerar det

Acrobat charges for filling and flattening forms, and iLovePDF gates flatten behind a sign-up. This fills interactive PDF forms and flattens them with pdf-lib, entirely in your browser.

1
You drop in a fillable PDF
The form fields (AcroForm) are read locally with pdf-lib — text boxes, checkboxes, dropdowns, radio buttons.
2
You fill in the fields
Each field is shown as an editable input, pre-filled with any existing value. Nothing is uploaded.
3
Values are written back
Your answers are written into the form. Optionally, the form is flattened — baking the values into the page so they can't be edited.
4
You download the result
The filled (and optionally flattened) PDF is offered for download.

Forms hold personal data — tax info, applications, contracts. Filling them on a server means uploading all of it. Here everything stays on your device, and flattening ensures recipients can't alter your answers.
