Common Questions
Is this tool suitable for medical forms?
Since all processing happens in your browser and files never upload to external servers, this tool provides strong privacy for sensitive documents. However, for HIPAA-covered entities, we recommend consulting with your compliance officer, as HIPAA requires specific administrative, physical, and technical safeguards beyond just local processing.
Are the signatures legally binding?
Electronic signatures are legally valid under the ESIGN Act (US) and eIDAS (EU). However, some organizations may require specific e-signature services. For most personal and business documents, drawn signatures are fully acceptable.
Can I fill password-protected PDFs?
Password-protected PDFs must be unlocked before editing. If you know the password, use a PDF password remover tool first, then fill the unlocked form here.
Will the filled form work in other PDF readers?
Yes. The filled PDF is a standard PDF file that opens in any PDF reader including Adobe Acrobat, Preview (Mac), Chrome's built-in viewer, and all major PDF apps.
Can I edit existing text in the PDF?
This tool is designed for adding new content to forms (text fields, signatures, annotations). It doesn't modify or delete existing text in the PDF. For text editing, you'd need a full PDF editor.
