Frequently Asked Questions — Illustrator to PDF

Find clear answers about FDM's secure vector compiler framework — how to safely convert AI files, preserve vector paths, and maintain high-fidelity design standards in 2026.

  • Q

    What is FDM’s Illustrator to PDF Converter?

    It is a high-performance vector compiler engineered to transform complex .ai documents into standard PDF layouts. The engine accurately maps proprietary vector nodes, typography, and color profiles into a secure PDF stream.

  • Q

    Is the converter free to use?

    Yes, it is 100% free with no registration walls. You can compile your vector assets with zero hidden execution fees, no mandatory software installs, and absolutely no watermarks.

  • Q

    How does the browser-side extraction work?

    If your .ai file includes a "PDF Compatibility Layer" (default in Illustrator), the browser instantly extracts the PDF stream. For pure PostScript vectors, our secure server-side Inkscape engine performs the compilation.

  • Q

    Will vector paths lose quality during conversion?

    No. We use a high-fidelity vector-to-vector transformation process. Anchor points, line weights, and geometric paths are preserved, ensuring your output PDF remains sharp at any zoom level.

  • Q

    Is my data secure during upload?

    Privacy isolation is our core priority. All uploads are processed via encrypted transmission layers. Files are temporary tokens that are automatically cleared upon compilation completion, blocking any persistent storage or telemetry.

  • Q

    Can I convert very large AI files?

    The interface supports files up to 50MB. This limit is set to ensure rapid compilation and prevent server-side memory bottlenecks, allowing for a seamless experience on all device profiles.
