Export to PNG

The Gantt toolbar includes a Print / Export to Image button that captures the current chart view as a full-resolution PNG file.
  1. Open the Gantt page you want to export.
  2. Set the Scale to the level you need (for example, W for weekly or M for monthly) so the chart shows the desired date range.
  3. Click the Print / Export to Image button in the toolbar.
  4. The export panel opens, rendering the entire Gantt chart as an image.
  5. Click Download to save the image as gantt.png to your local machine.
The export captures the chart at the current zoom level. Switch to a wider scale (such as M or Q) to fit more of the timeline into the exported image, or use a narrow scale (such as D) for detailed views of a shorter time range.
To print the Gantt chart to a PDF file, use the browser’s built-in print dialog:
  1. Click the Print / Export to Image button in the toolbar.
  2. In the export panel, click Print.
  3. The browser’s native print dialog opens with the Gantt image pre-loaded.
  4. Select Save as PDF (or your preferred printer) as the destination.
  5. Set the page size to A0 or another large format to accommodate the full chart width.
  6. Choose Landscape orientation for best results.
  7. Click Print or Save.
To close the export panel without downloading or printing, click Close.

Print from a Cloned Page

For precise control over the printed layout, clone your Gantt page and configure it specifically for printing:
StepAction
1Clone your Gantt page to create a dedicated print version
2Open the cloned page and enter Edit mode
3Ensure Maximize mode is turned off
4Go to Sidebar > Page Properties and set the minimal width to 5000
5Set the Gantt Scale to the desired level (e.g., W)
6Save the page
7Click the Print / Export to Image toolbar button
8Close the system print dialog if it appears
9Wait for the page to fully render
10Click Print and select A0 page size
11Choose Print to PDF as the output
Fullscreen (maximize) mode interferes with the print layout. Always turn off maximize mode on your print-dedicated page before exporting. See Use Fullscreen and Maximize Mode for details.
For Gantt charts with many work items, the export process requires careful zoom and page-size adjustments. Experiment with the Scale parameter and page width to find the best balance between readability and chart coverage.

​
Verification

After completing the export, you should now see:
  • A gantt.png file in your downloads folder (for PNG export).
  • A PDF file containing the full Gantt chart (for print-to-PDF).
  • The chart image matches the scale and time range you configured before exporting.
