AI to PDF

Why convert AI to PDF?

AI is an image file and PDF is a document file. PDF opens on almost any device, while AI often needs extra software.

  • One file to share and print

    Put one or more images into a single PDF that opens and prints the same on any device.

  • Opens everywhere

    PDF opens in every browser, phone and computer, while AI needs Adobe Illustrator; partly in Inkscape and Affinity Designer.

  • Where PDF works best

    Sharing and printing documents that must look the same everywhere.

What is an AI file?

Adobe Illustrator Artwork

Developed By
Adobe Inc.
Initial Release
1987
MIME Type
application/postscript

The Adobe Illustrator Artwork (AI) format is a proprietary vector graphics file type developed by Adobe Systems for representing single-page vector-based drawings in either the EPS (Encapsulated PostScript) or PDF (Portable Document Format) standards. Early versions utilized a simplified PostScript syntax (PGF), while modern versions (version 9 and later) rely on a PDF-compatible structure containing an embedded PGF copy for backward compatibility. The format supports scalable paths, distinct layers, and CMYK color models, making it a standard in the commercial print and digital graphics industry.

How to open an AI file

Opening AI files natively requires Adobe Illustrator. However, files saved with PDF compatibility enabled can be viewed in Adobe Acrobat, Apple Preview (macOS), or standard PDF readers. For editing without Adobe subscriptions, users can utilize vector graphics software such as CorelDRAW, Inkscape (via import), or Affinity Designer. Non-compatible AI files (saved without PDF data) may strictly require Illustrator or specialized conversion tools.

What is a PDF file?

Portable Document Format

Developed By
Adobe Inc. / ISO
Initial Release
1993
MIME Type
application/pdf

The Portable Document Format (PDF) is a comprehensive file format, standardized as ISO 32000, designed to present documents consistently independent of application software, hardware, and operating systems. It encapsulates a complete description of a fixed-layout 2D document, including text, fonts, vector graphics, and raster images, based on the PostScript language. Advanced implementations support interactive form fields, JavaScript scripting, 3D objects (U3D/PRC), and various encryption standards.

How to open a PDF file

PDF viewing is natively supported by all major modern web browsers (Chrome, Edge, Firefox, Safari) and most operating systems via built-in previewers. For advanced manipulation, form filling, or pre-press validation, dedicated software such as Adobe Acrobat DC, Foxit Reader, or open-source tools like Ghostscript and Poppler is required.
