Someone on your team just emailed a logo file to a print vendor, a web developer, and an embroidery shop, and sent the exact same file to all three. That is usually a mistake, not a convenience. Vector formats look interchangeable because they all promise the same thing, infinite scaling with no pixelation, but they are built for different jobs, and using the wrong one is one of the quietest ways a logo degrades without anyone noticing until production day.
What each format actually does
SVG is built for screens. It is lightweight, it renders natively in browsers, and it is the right choice for a website, an app icon, or anything that lives online. What SVG does not guarantee is print fidelity: color profiles, embedded fonts, and bleed handling are not its job.
EPS is the print world's old workhorse, built to preserve vector paths across professional design software with predictable results in a commercial print house. It is dated and clunky to open casually, but a lot of large-format and specialty printers still expect it, and asking for it by name saves a round trip.
PDF is the generalist, capable of holding vector art, embedded fonts, and specific color profiles like CMYK or Pantone spot colors, all in one file most humans can actually open. It has become the safest default for sending a logo to almost anyone who is not building a website.
What goes wrong when the formats get mixed up
- An SVG built for RGB screens gets sent to a printer expecting CMYK, and the color shifts on press
- A PDF with unembedded fonts gets opened on a machine without that typeface installed, and the wordmark silently substitutes a system font
- An EPS gets dropped into a modern web build tool that has no idea what to do with it, and someone burns an afternoon converting a file that should have been an SVG from the start
None of these failures announce themselves loudly. They show up as a color that is slightly off, a font that is subtly wrong, or a vendor asking for a file that should have been in the original delivery package.
Build the kit once
The fix is not learning file format trivia on demand every time a vendor asks. It is building a small delivery kit up front: an SVG for digital, a print-ready PDF with fonts embedded and colors specified, and an EPS on hand for the vendors who still ask for it by name. Hand over the right one before anyone has to guess.
A logo file is not finished when the design is approved. It is finished when it exists in the format the next person actually needs.
