The short answer
An AI file is an Adobe Illustrator Artwork file. It is a vector format, which means the artwork is built from shapes and paths rather than pixels, so it scales to any size without going blurry. Designers use it for logos, icons, type, and illustrations that need to stay crisp on everything from a business card to a banner.
Because it is Illustrator's native format, an AI file keeps every layer and path editable, and that is also why it can be hard to open without the right software.
How to open an AI file
- Adobe Illustrator opens it natively with everything editable.
- Inkscape, a free vector editor, opens many AI files, especially ones saved with PDF compatibility.
- Photopea, a free browser tool, can open AI files for viewing and light editing.
- A PDF reader can sometimes display an AI file, since Illustrator often embeds a PDF preview inside it.
How to convert an AI file
If you need a format that opens anywhere:
- In Illustrator, use Save As or Export to create a PDF, SVG, PNG, or JPG.
- In Inkscape, open the AI and export to SVG or PNG.
- For a quick one off, a free online converter handles AI to PDF or PNG.
Pick SVG to keep it scalable, or PNG and JPG for a flat image that opens on any device.
How to share an AI file
AI files are often too large for email and useless to anyone without the software. Send a usable version as a link.
- Export a PDF or PNG preview, or zip the AI if the other person needs to edit it.
- Upload it to snapy.
- Share the link. They click and get the file, no account needed.
