Sign Consent Forms Online — Fast, Private, Legally Valid

Consent forms are among the most privacy-sensitive documents you will ever sign. A medical consent form may detail your health conditions, medications, allergies, and surgical history. A photo release form ties your identity and likeness to specific usage rights. A data processing consent form under GDPR governs how a company handles your personal data. These documents deserve the highest level of privacy when being signed — yet most e-signature platforms require you to upload them to third-party servers where they can be stored, accessed by employees, or exposed in a data breach.

SigPDF works differently. When you sign a consent form with SigPDF, the entire process happens inside your browser using client-side JavaScript. Your PDF file never leaves your device. It is not uploaded, not transmitted, and not stored anywhere except on your own computer or phone. For medical consent forms containing protected health information, this browser-based approach eliminates the risk of third-party exposure entirely.

Types of Consent Forms You Can Sign

SigPDF handles any consent form that comes as a PDF. Common types include:

• Medical consent forms — Informed consent for surgery, procedures, treatments, vaccinations, and clinical trials
• Photo and video release forms — Consent to use your image or likeness for marketing, media, events, or publications
• Data processing consent (GDPR) — Consent for companies to collect, process, and store your personal data under the General Data Protection Regulation
• Research participation consent — Informed consent for participation in academic or scientific studies
• Background check consent — Authorization for employers to conduct criminal, credit, or employment history checks
• Parental consent forms — Permission for minors to participate in activities, receive medical care, or be photographed

Legal Validity of Electronically Signed Consent Forms

Electronic signatures on consent forms are legally binding under the major legal frameworks governing e-signatures:

• ESIGN Act (United States): The ESIGN Act provides that electronic signatures on consent documents are valid and enforceable. This includes medical informed consent, research participation consent, and commercial consent forms. Healthcare providers have increasingly adopted electronic consent as standard practice.
• eIDAS Regulation (European Union): Under eIDAS, a simple electronic signature — like one drawn or typed with SigPDF — cannot be denied legal effect solely because it is in electronic form. For GDPR data processing consent, an electronically signed consent form provides clear, demonstrable evidence of the data subject's agreement.

Note that certain medical contexts may have additional requirements (such as witness signatures or specific disclosure language). SigPDF handles the signature portion; always ensure the form itself meets the applicable regulatory requirements for your situation.

Traditional Signing vs. SigPDF

Traditionally, signing a consent form means receiving a paper form at a doctor's office, clinic, event registration desk, or by mail. You sign it by hand and return the physical copy. If you receive the form as a PDF by email, you face the print-sign-scan-email cycle that wastes time and requires equipment you may not have. For patients preparing for a medical procedure, adding the stress of finding a working printer to pre-surgery anxiety is the last thing they need.

With SigPDF, you open the consent form PDF, add your signature, and download the signed document — all in under a minute, from any device with a browser. It is faster, easier, and more private than any alternative.

Privacy First — Especially for Medical Documents

Medical consent forms contain protected health information (PHI) that is regulated under HIPAA in the United States and GDPR in the European Union. Uploading these documents to a cloud signing platform introduces third-party risk. SigPDF eliminates that risk by processing everything locally. Your health information stays on your device and nowhere else.
