How to Create a Gantt Chart Online Free — Project Timeline Tool

What Is a Gantt Chart?

A Gantt chart plots project tasks on a timeline. Each task is a horizontal bar spanning its start and end dates. Dependencies between tasks show which work must complete before other work can begin. It is the most common way to visualize project schedules, and tools like Microsoft Project charge $30+/month just to make one.

How to Create a Gantt Chart

1. Open the Gantt Chart tool
2. Define tasks with names, start dates, and durations
3. Add dependencies between tasks
4. The timeline renders automatically
5. Export as PNG or SVG for presentations and documents

Text-based input means fast iteration. Change a date, see the timeline update instantly. No subscription required.

Planning a Project with Gantt Charts

• Break work into tasks — each task should be a concrete deliverable
• Estimate durations — be realistic, pad estimates by 20% for unknowns
• Define dependencies — what must finish before something else can start?
• Identify the critical path — the longest chain of dependent tasks determines your minimum project timeline

Common Use Cases

• Product launches — map out design, development, testing, and release milestones
• Event planning — track venue booking, vendor coordination, and marketing timelines
• Construction projects — sequence phases with dependencies
• Client proposals — include a visual timeline in project proposals
