Fill PDF Form
Drop a fillable PDF — an IRS W-9, W-4, I-9, a state tax-exemption certificate, an application — and type directly into its fields, tick the boxes, pick the options, then download. No Adobe, no upload: your SSN, EIN and details never leave your device.
Frequently asked questions
Does it work with IRS forms like W-9, W-4 and I-9?
Yes. Official IRS and state forms are interactive PDFs (AcroForms). Drop the official form and type straight into its fields. Always use the current official form from irs.gov or your state site.
Is my form uploaded anywhere?
No. The form is rendered, filled and saved entirely in your browser. Your SSN, EIN and personal details never leave your device.
What if my PDF has no fillable fields?
Switch to Fill anywhere mode: click on the page to place text or a checkmark wherever you need it, then download. Works on flat and scanned forms.
What does Flatten mean?
Flattening bakes your answers permanently into the page so they can't be changed and display identically in every viewer. Leave it off to keep the form editable.
