AI: the native format of Adobe Illustrator
An AI file (.ai) is the standard file format of Adobe Illustrator, the world's most widely used vector design program. When a printer, sign maker or designer asks for your 'logo files', they almost always mean an .ai file. But what exactly is this format and why is it so important?
How does an AI file work?
An AI file stores your design as vector data: mathematical descriptions of shapes, lines, colours and text. Unlike pixel files, an .ai file does not contain a grid of coloured dots but instructions to draw shapes. This makes an AI file infinitely scalable. Additionally, the format preserves all editing data: layers, anchor points, colour swatches, fonts and effects. This makes the file fully editable in Illustrator.
Benefits of an AI file
Fully editable source file
An AI file retains all layers, effects and editing capabilities. Every colour, shape and line can be adjusted individually. This makes it ideal as the master file of your logo.
Infinitely scalable without quality loss
From a business card to a billboard: an AI file can be scaled to any size while always remaining sharp and clear. This is essential for a consistent brand image.
Widely accepted in the industry
The AI format is the standard among printers, sign makers, embroiderers, vinyl cutters and advertisers. Virtually every professional supplier can work with an .ai file.
AI file compared with other formats
Raster formats (JPG, PNG, BMP)
Raster files consist of a fixed number of pixels and become blurry when enlarged. They cannot be edited at element level and must be supplied in different resolutions for different applications.
AI file (vector format)
An AI file is infinitely scalable, fully editable and serves as the source file from which all other formats can be derived. It is the professional master file of your logo.
What do you need an AI file for?
Print materials
Business cards, letterheads, brochures, banners and all other printed materials require a vector file. Printers almost always ask for an .ai or .pdf file of your logo.
Signage and lettering
Facade signage, vehicle wraps, window lettering and illuminated signs are produced from vector files. An AI file ensures sharp cutting contours and perfect output.
Merchandise and products
Printed clothing, promotional items, packaging and other products require a vector logo. Embroidery machines and vinyl cutters work with the vector paths from an AI file.
Frequently asked questions about AI files
Can I open an AI file without Illustrator?
To a limited extent. Inkscape (free) can import AI files, but not all features are displayed correctly. An AI file saved with the 'PDF compatible' option can also be viewed in PDF viewers, but not edited.
Is an AI file the same as a vector file?
An AI file is always a vector file, but not every vector file is an AI file. Other vector formats include SVG, EPS and PDF. AI is the native Illustrator format and offers the most editing capabilities.
My designer did not deliver an AI file. What now?
Ask your designer for the source file. Only have a JPG or PNG? Then your logo needs to be vectorized. Logo in Vector can do this for you and delivers a fully editable AI file.
How large is an AI file typically?
An AI file of a logo is usually between 100 KB and 5 MB. The size depends on the complexity of the design and whether there are embedded images. Pure vector logos are compact and efficient.
Make sure you have an AI file of your logo
An AI file is the most important file in your visual identity. It is your master file from which all other variants are derived. Do not have an AI file of your logo? Logo in Vector creates a professional vector file from any image. Upload your logo and receive a perfect .ai file quickly.
