How to make a Gantt chart

  1. Paste your tasks: name, start date and end date (or a number of days) on each line.
  2. Add a group and progress % if you like, and a title.
  3. Download it as PNG, SVG or PowerPoint.

What it shows

  • A bar for each task, from its first to its last day, with its length in days or its progress.
  • Colors by group (Planning, Design, Build…), with a legend.
  • Milestones: a task that starts and ends on the same day is a diamond.
  • A "today" line, and a time scale in days, weeks or months to fit the plan.

Dates

  • Dates can be 2026-10-12, 12/10/2026, 12 Oct 2026 or Oct 12, 2026. Choose whether your dates are written day first or month first.
  • Instead of an end date, give the number of days: 5 means the task lasts five days.
  • Dates copied from Excel as numbers (such as 46307) are understood too.

Your plan stays on your device

常见问题

Can I edit the chart later?

Yes. Save the PNG, and open it here again with "Open a chart PNG made here": the task list and settings come back.

Is it a full project planning app?

No: it draws a timeline from your list. Dependencies, working days and resources aren't calculated. Keep the plan in your spreadsheet and paste it here whenever it changes.
