Convert PDF to ASICE

Understanding PDF and ASiC-E file formats

PDF (Portable Document Format) is a widely used file format developed by Adobe for presenting documents in a manner independent of application software, hardware, and operating systems. It preserves the formatting of a document and allows for secure sharing and printing.

ASiC-E (Associated Signature Containers - Extended) is a European standard container format for electronic signatures. It bundles one or more files (such as PDFs) together with their digital signatures and related metadata, ensuring the integrity and authenticity of the documents.

Why convert PDF to ASiC-E?

Converting a PDF to an ASiC-E container is essential when you need to digitally sign documents in compliance with European eIDAS regulations. The ASiC-E format ensures that the PDF and its signature are securely packaged together, making it suitable for legal and official electronic transactions.

How to convert PDF to ASiC-E

To convert a PDF to an ASiC-E file, you need specialized software that supports digital signatures and the ASiC-E container format. The process typically involves digitally signing the PDF and then packaging it into an ASiC-E container.

Recommended software for PDF to ASiC-E conversion

• DigiDoc4 Client (by SK ID Solutions): A free and widely used tool in the EU for creating ASiC-E containers and digitally signing documents.
• Adobe Acrobat Sign: Supports digital signatures, but for ASiC-E packaging, integration with third-party tools may be required.
• eIDAS-compliant online services: Platforms like Signicat or D-Trust offer web-based ASiC-E signing and packaging.

Step-by-step conversion using DigiDoc4 Client

1. Download and install DigiDoc4 Client from the official website.
2. Open the application and select New container.
