Complete interactive PDF forms online: text boxes, checkboxes, radio buttons and dropdowns. Flatten your answers and download — free and private.
PDF Form Filler lets you complete interactive PDF forms directly in the browser, handling text boxes, checkboxes, radio buttons and dropdown menus exactly as they were designed in the original document. Once every field is filled in, you can flatten the form so the answers become permanent, uneditable content, then download the completed PDF.
It's built for the common scenario of receiving a fillable PDF — an application, tax form or agreement — that needs to be completed and returned without printing it out by hand. Because the form data is processed locally, nothing you enter into personal or financial fields is transmitted to a server during the process.
Text boxes, checkboxes, radio buttons and dropdowns are all recognised and rendered as their original interactive controls, rather than forcing you to type answers into a static overlay.
Flattening converts your filled answers into fixed content that can't be altered later, which is useful when sending the final version, while leaving it unflattened keeps fields editable if further changes are expected.
Because the form is filled and processed locally in your browser, personal and financial details entered into the fields are never uploaded to a remote server.
If a document is a flat, non-interactive PDF rather than a true form, there are no fields to fill in directly. Use the Edit PDF Text tool or the Sign PDF tool instead to place typed text or a signature anywhere on the page manually.
Flatten the form before sending the final version to prevent anyone else from altering the answers after submission. Leave it unflattened if you expect to come back and make further edits yourself, since flattening removes the ability to click back into individual fields.
Because interactive fields can sometimes be easy to overlook, especially checkboxes near the edge of a page, it's worth scrolling through every page of the completed form once more before flattening and downloading, to confirm nothing required has been left blank.
Then it is a flat document. Use Edit PDF Text or Sign PDF to place text and signatures anywhere on the page.
Flatten it when sending the final version so nobody can alter your answers. Leave it unflattened if you still need to edit later.
