Frequently asked questions about Instafill.ai Form Filler
Is Instafill.ai secure?
Yes. Instafill.ai is built with multiple layers of security to protect your data. You can use stateless mode as an option, which ensures all files are automatically deleted after processing, leaving no traces behind. By default, all data is processed and stored securely on Microsoft Azure’s private, non-public infrastructure—fully hosted in the United States. Your data never leaves the country during processing. Our primary data center is a 470,000 sq. ft. facility located at 5150 Rogers Rd, San Antonio, TX.
Does Instafill.ai support two-factor authentication (2FA) for account login?
Yes. Instafill.ai supports two-factor authentication as an optional security feature for your account. If you sign up or log in with an email and password, you can enable 2FA to add an extra layer of protection. Organization administrators also have the ability to require 2FA for all members, so you might be prompted to set up 2FA when logging in if your team enforces it. Enabling 2FA is recommended as it significantly increases the security of your account, helping to keep your data safe.
What makes Instafill different from other PDF fillers or document automation tools?
Instafill.ai is an AI-powered PDF filler designed to automate even the most complex form workflows. It can fill out PDFs in 25–60 seconds, handle up to 100 pages and hundreds of fields, and supports all common input types including checkboxes, tables, and radio buttons. Unlike traditional tools, it can convert flat, scanned, XFA, and Word documents into fillable PDFs — and learns from each fill to improve accuracy. It also offers secure features like stateless mode, 2FA, team access, and full API/webhook support, all hosted on Microsoft Azure in the US.
What does Instafill.ai do with my uploaded documents?
We take security very seriously and aim for full transparency. All uploaded files are immediately deleted from our servers after processing, leaving no traces. Whether you're using our AI PDF filler for government forms or our AI document filler for personal paperwork, your data is always protected.
What if my document isn’t a fillable PDF form? Can Instafill.ai’s PDF filler complete it?
Yes. If your document isn’t a fillable PDF—like a flat PDF, scan, image, or XFA form—Instafill.ai can automatically convert it into a fillable PDF format. Once converted, our AI PDF filler can complete it just like any standard form.
Can I fill out the same form multiple times?
Yes. Instafill.ai supports batch form filling. Upload a CSV file containing the data needed to complete the form, and the AI will do the rest. Once completed, you can download all forms at once as an archive or individually, one by one.
Do you use my data to train AI?
No. We do not use your data to train AI. Instafill.ai relies on AI models hosted in the United States, managed by OpenAI, and your data is never sent overseas. For more details, see OpenAI’s Security & Privacy Policy.
Does anyone at Instafill.ai have access to my files?
No. Since your files are immediately deleted after processing, no one at Instafill.ai can access them. This includes forms completed using our AI form filler free version or the full-featured service.
Fun fact: When users ask us for help with filling out their forms, we often need to ask what form they’re using and what data they provided—because we don’t have access to their files.
Can I fill out a form for someone else?
Yes, you can use Instafill.ai's custom Profile feature to fill out documents on behalf of others. Whether it's a visa application, tax return, or insurance claim, our AI makes the process simple and efficient.
Why does filling out PDF forms with AI actually work?
Recent advancements in AI, like those used in Instafill.ai, have made it possible to:
- Understand form fields based on their descriptions and instructions embedded in the PDF.
- Parse and interpret user-provided information, even if it's in an unconventional format. Our AI to fill out forms can process messy or non-standard inputs like scans or photographs.
- Reason through form-filling logic – Modern AI can analyze context, apply logic, and ensure accuracy. That’s why Instafill.ai supports formats such as PDFs, Word documents, scans, and images.
My form has no instructions. Can I still fill it online with Instafill.ai?
Yes. You can upload additional instructions or comments for our AI application filler. If no instructions are provided, our AI form filler can extract field meanings from the built-in descriptions. However, for complex forms, this might increase the risk of errors.
