Upload a PDF.
Find the fields and fill it with AI.

Upload your PDF to iFillPDF — the AI assistant automatically detects the fields (text, checkboxes, dropdowns) and proposes a fill from your profile or from a natural-language instruction. You review, sign if needed, then download the filled PDF in seconds.

On the web, fill, edit and sign PDFs for free with no document limit and a watermark on exports. The currently available Lifetime offer removes that watermark for $8.99 as a one-time payment, with no subscription. AI Deep Detect credits for advanced recognition and smart pre-filling are purchased separately and never expire: 1 credit = 1 analyzed document. A free account is required to download from the editor.

Yes. PDF utilities (merge, compress, convert…) run 100% in your browser — your files never leave your device. For AI filling, traffic goes through servers hosted in the European Union (Frankfurt), GDPR-compliant, with no model training on your data.

All of them: government forms (W-9, IRS, immigration…), leases, inspection reports, quotes, invoices, sworn statements, freelance contracts, cover letters. iFillPDF supports interactive fields (AcroForm) as well as scanned PDFs thanks to AI detection.

No. iFillPDF runs straight from your browser (Chrome, Safari, Firefox, Edge), on desktop, iPhone or Android. No install, no extension, no account required to get started.

Unlike Smallpdf, iLovePDF or PDF24, iFillPDF uses AI to automatically pre-fill fields from your profile or an instruction. It is a European alternative to Adobe Acrobat, with a single lifetime payment instead of a monthly subscription, GDPR-compliant, and hosted in Europe.
