Receiving your logo is good. Knowing which file to send the printer, the developer or the community manager is what keeps your logo from going blurry on a banner. A clear little guide.
Two main families
It all comes down to one distinction: vector or raster (bitmap). A vector file is made of mathematical paths: it scales infinitely with no loss. A raster file is made of pixels: enlarged beyond its size, it goes blurry. A good logo always exists first in vector.
Vector formats
- AI: the source file (Illustrator), the designer's, to keep carefully.
- EPS: the exchange format for print, universal among printers.
- SVG: the web vector, light, sharp at any size, ideal for a website.
- PDF: handy to share a vector version readable everywhere.
A logo that only exists as a PNG is a half-delivered logo. Without the vector, you are stuck at the first large print.
Raster formats
- PNG: pixels with a transparent background, perfect for web and presentations.
- JPG: pixels with no transparency, best kept for photos, rarely ideal for a logo.
- WebP: a modern web format, light, a good quality-to-weight compromise.
Which format for which use
- Printer, large format, merch: vector (EPS, AI or PDF).
- Website: SVG first, otherwise PNG or WebP.
- Social media, presentations: PNG with a transparent background.
- Favicon: a simplified version, legible at very small size.
A serious logo deliverable contains all these versions, clearly named. It is also what a brand style guide frames: not only the drawing, but the right files for the right uses.
Frequently asked questions
-
What is the difference between vector and PNG?
- Vector (SVG, EPS, AI) scales with no loss, PNG is made of pixels and goes blurry beyond its size. A logo must always exist in vector.
-
Which logo format for a website?
- SVG first: light and sharp at any size. Failing that, a PNG or WebP with a transparent background.
-
Why do you need your logo's vector file?
- Because without it, large-format printing or clean applications are impossible. A logo delivered only as a PNG is incomplete.
