Fill a PDF Form — Free, Browser-Only

Open a fillable PDF (IRS forms, leases, onboarding docs, etc.), click on fields, type your answers, and download. Works with standard AcroForm fields: text, checkbox, radio, dropdown.

Your answers stay in your browser — nothing uploads.

Open the editor

How it works

Open wt-pdf.com and drop in the fillable PDF.
Click any highlighted field and type your answer. Tab to move field-to-field.
Check boxes, pick from dropdowns, select radio options.
Click Download to save the filled PDF — the form remains editable by others unless you Flatten.

Keep the form editable or flatten it

By default the downloaded PDF stays editable (recipients can modify your answers). Use the Flatten button to bake your answers into the page content so they can't be changed.

Signature fields

For signature fields, use the Sign tool to draw or upload a signature and place it in the field.

FAQ

Is my filled data uploaded anywhere?

No. Everything happens in your browser.

What if the PDF isn't fillable?

Use the Text tool to add overlay text anywhere on the page.

Can I save and come back?

Download the in-progress PDF and reopen it later — your entries are preserved.
