Open AI files without Illustrator
A designer sent a dieline, a logo or a poster as .ai and you don't have Illustrator. Omia opens it on Mac or Windows so you can check the artwork — offline, without an Adobe account.
Free to view · 5 free saves, conversions & pro-format opens · then $19.90 one-time · no subscription · files never leave your computer

What it doesn't do
We'd rather you know before downloading.
- View only: you can't edit paths, text or layers
- Files saved with Illustrator's “Create PDF Compatible File” turned off, and very old PostScript-only .ai files, won't display
How to open AI files
- Download Omia and install it (Mac or Windows)
- Double-click the .ai, or drag it onto the Omia window
- Zoom in to check the details
Why a local viewer
Uploading an unreleased logo or packaging file to a web viewer is exactly what your client asked you not to do. Omia opens it on your own computer.
FAQ
How can I open an AI file without Illustrator?
Install Omia and double-click the .ai file. Modern Illustrator files open right away because Illustrator saves a PDF-compatible copy inside them by default.
Why won't my .ai file open?
It was probably saved with “Create PDF Compatible File” switched off, or it's a very old PostScript-based file. Ask the sender to re-save it with PDF compatibility on, or export a PDF.
Can I edit the artwork?
No. Omia is a viewer for AI files.
Is it free?
Viewing files is free forever, with no sign-up. Saving edits, converting, and opening pro formats (DWG, STEP, SketchUp, CorelDRAW) each come with 5 free uses; after that it's a one-time $19.90 licence, no subscription.
Are my files uploaded?
No. Omia opens and converts files on your own computer. Nothing is sent to a server or an AI service.
Omia also opens: PSD · SVG · PDF · DXF · 150+ formats in one app
