Fill PDF Forms Online Free
Complete fillable PDF forms right in your browser. The tool reads the document’s own fields — text boxes, checkboxes, and dropdowns — so you can fill them in and download, with nothing uploaded.
Frequently Asked Questions
Is my PDF uploaded to a server?
No. The form is read and filled entirely in your browser with pdf-lib. Your data never leaves your device — important for forms with personal information.
What kinds of fields are supported?
Existing AcroForm fields: text fields, checkboxes, dropdowns, radio groups, and list boxes are all detected and editable.
Can it create new form fields?
No. This tool fills forms that already contain fillable fields. It does not add new fields to a flat PDF.
What does “flatten” do?
Flattening bakes your answers into the page so the values are permanent and can no longer be edited — useful before sharing a completed form.
Is it free?
Yes — completely free, no account, no watermark, no limits.
