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.
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.
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.
