Webinar and seminar sound almost the same, and the word webinar was in fact formed from “web” and “seminar.” Today, though, the two formats usually work quite differently. A seminar is typically a small, discussion-based session, while a webinar is usually an online presentation to an audience. This guide explains the difference between a webinar and a seminar, compares them side by side, and helps you choose the right one.
Webinar vs. Seminar: The Short Answer
A seminar is a session where a small group studies or discusses a topic together, guided by a leader, with participants expected to contribute. A webinar is a live online presentation, lecture, or workshop delivered over the internet to an audience that participates mainly through chat, polls, and Q&A. A seminar can happen online, but an online seminar keeps the discussion format. A webinar usually has presenters and an audience.

What Is a Seminar?
In universities, a seminar is a small class built around reading, discussion, and presentations by students. In professional settings, the word is also used for an educational event on a single topic, such as a one-day seminar on employment law, which may include more presenting than discussion. Either way, a seminar tends to be focused, relatively small, and interactive. For a full explanation, see what is a seminar.
What Is a Webinar?
A webinar is a live online event where one or more presenters share content with an audience in real time. Attendees register, join through a browser or app, and participate through chat, polls, reactions, and questions. Many webinars are recorded and shared afterward. For a full explanation, see what is a webinar.
Key Differences Explained
Interaction
The biggest difference is how much participants are expected to contribute. In a seminar, discussion is the point. In a webinar, participation is usually lighter and more structured, though a well-designed webinar includes regular interaction.
Scale
Seminars rely on conversation, so they stay small. Webinars scale easily, which is why organizations use them to reach large or distributed audiences.
Preparation
Seminar participants often prepare in advance by reading, writing, or bringing a case. Webinar attendees usually just show up.
Purpose
Seminars aim at deeper understanding through dialogue. Webinars often aim to inform, introduce, or demonstrate, and they are widely used for marketing and lead generation as well as education.
Online Seminar vs. Webinar
An online seminar, sometimes called a virtual seminar, keeps the seminar’s small size and discussion format but uses a video meeting tool. Everyone has their camera on, participants speak rather than type, and the leader guides conversation. If your session is a small, discussion-heavy group meeting online, “online seminar” is more accurate than “webinar.”
Which Should You Choose?
- Choose a seminar when you want participants to think together, analyze material, and build understanding through discussion, and the group is small enough for everyone to speak.
- Choose a webinar when you need to reach many people, especially in different places, share expertise or a demonstration, and create a recording people can watch later.
- Choose a workshop when people need to practice a skill or produce something. See workshop vs. seminar.
Frequently Asked Questions
Is a webinar the same as a seminar?
Not quite. The word webinar comes from “web seminar,” but most webinars today are online presentations to an audience, while seminars are smaller and centered on discussion.
Is a webinar formal or informal?
It can be either. Corporate and academic webinars are usually fairly formal, while community webinars and interviews can be conversational.
What is the difference between a webinar and a workshop?
A workshop focuses on hands-on practice and producing something together. A webinar focuses on presenting information, though it can include workshop-style activities.
Are seminars only for universities?
No. Professional organizations, businesses, and associations run seminars for training and professional development.
