Here's the short answer: use a vector file (SVG, EPS or PDF) as your master and for anything that scales or prints, and use PNG for the web when you need transparency. Everything else is a detail. This guide explains what each format is for so you always send the right file.
Vector vs raster: the one concept that matters
Raster files (PNG, JPG) are made of pixels, so they blur or pixelate when enlarged. Vector files (SVG, EPS, PDF, AI) are made of math, so they scale to any size, from a billboard to a favicon, with perfect sharpness. Your logo's master should always be a vector; you generate raster versions from it as needed.
Keep one vector master. Export pixels from it. Never the other way around.
The formats, and when to use each
SVG
The modern web standard for logos. It's a vector, so it stays crisp at any size, it supports transparency, and the file is tiny and fast to load. Use SVG for your logo on websites and apps wherever you can.
PNG
A raster format with transparency support. Perfect for placing your logo on colored backgrounds, in email signatures, on social platforms, and anywhere SVG isn't accepted. Export at 2–3× the display size for sharpness on high-resolution screens.
JPG
A compressed raster format with no transparency. Every JPG has a solid background. Fine for photos; generally a poor choice for logos because of the missing transparency and compression artifacts around crisp edges.
A universal vector-capable format that almost anyone can open. Ideal for sending your logo to a printer, or sharing with people who don't have design software but need a high-quality, scalable file.
EPS and AI
Older vector formats still requested by some printers and professional designers. If a print vendor asks for "vector artwork," an EPS or PDF is usually what they mean.
ICO / favicon
A tiny square version of your mark for browser tabs and bookmarks. This is why designing a logo that still reads at 16–32 pixels matters so much.

Get the AppA quick cheat sheet
- Website or app: SVG (PNG as a fallback).
- Logo on a colored background: transparent PNG.
- Sending to a printer: vector PDF or EPS.
- Social profile picture: high-resolution PNG, square.
- Browser tab: ICO / favicon.
Keep a clean vector master, export the right raster versions when you need them, and you'll never hand over a blurry logo again.
