What you can do for free
- Make as many charts as you like, from pasted rows, a dropped .xlsx/.csv file, or by typing into the table.
- Tasks, milestones (diamonds) and phases (summary bars), with finish-to-start, start-to-start and finish-to-finish dependencies and lags.
- % complete shown on each bar and rolled up into each phase, weighted by duration.
- Owners as a column (on a phone they move onto the bar labels), or as the colour key.
- Six themes, including a dark one for slides and a greyscale one for printing.
- Day, week, month or quarter scale, chosen automatically to fit or set by you.
- Weekends and public holidays skipped in durations and shaded on day scales.
- A today line, so the same chart works as a status update.
- Downloads as PNG (at double resolution) and SVG, with no watermark, plus the table as CSV.
The only paid features are the editable PowerPoint and the PDF, at one credit per chart. Downloading the same unchanged chart again doesn’t use another credit.
Starting from scratch
Press Start blank above and type into the Edit tasks table. Each row has an ID, a type (task, milestone or phase), a name, start and end dates, working days, owner, % done and a Depends on cell. A few things make it quick:
- Leave Start empty and fill Depends on with the ID of the task before; the start date is worked out, shown in grey, and moves when the earlier task moves.
- Type a number of Days and the end date follows, skipping weekends and the holidays you chose. Set an End date instead and the days are counted for you.
- Press
Enterto move down a column, like a spreadsheet. - Use + Phase to add a heading; every row below it, up to the next phase, belongs to it.
- Click any bar in the chart to jump to its row.
Your chart is kept in this browser (local storage), so it is still there when you come back on the same device. It is not stored on a server, so there is nothing to log in to and nothing to delete. Download the CSV if you want a copy elsewhere.
What it isn’t
GanttPaste is for turning a plan into a clear chart quickly. It is not a project management system: there is no shared workspace, no comments, no time tracking, no resource levelling and no critical-path analysis. If a team needs to update the plan together every day, a hosted tool fits better. TeamGantt, for example, has a free plan for one user, one project and 40 tasks, and paid plans from $59 a month (prices on its site, November 2026). If you need a chart for a document, a slide or a status email from a list you already have, this is faster.
Gantt chart basics
A Gantt chart lists tasks down the left and time across the top. Each task is a bar from its start to its end, so you can see what runs in parallel, what waits on what, and when the work finishes. Milestones mark zero-length events like a sign-off or a launch, drawn as diamonds. Phases (also called summary tasks) group related work and span from their first task’s start to their last task’s end. Arrows show dependencies: by default, a task can’t start until the one it depends on finishes.
Start typing in the table above, or paste rows. Charts, editing, PNG and SVG are free with no sign-up. Editable PowerPoint and PDF cost one credit per chart (10 for £5).
