## Questions
### What is gray out?
gray out is a free online tool for highlighting part of a chart. You click a bar, line, area or label, and everything else in the image is grayed out and faded. It makes one point stand out in a slide or report without remaking the chart.

### How do I highlight one series in a bar chart?
Paste or upload the chart, choose the “Same colour” tool and click any bar of the series. Every bar in that colour stays in full colour and the rest of the chart turns gray. Use the Gray and Fade sliders to set how strong the effect is.

### Are my images uploaded to a server?
No. All image processing happens in your browser. Your images never leave your device, so the tool is safe to use with confidential client data.

### Which images work best?
Charts, diagrams and screenshots with clear, flat colours: bar charts, line charts, pie charts, maps with coloured regions and dashboard screenshots. Photos are not supported yet.

### Does it work with charts from Excel, PowerPoint, Power BI, Tableau or R?
Yes. Take a screenshot or export the chart as an image, paste it into gray out with Ctrl+V or ⌘+V, highlight what matters, then copy the result back into your slides.

### What is the difference between Free and Pro?
Free includes all selection tools, with exports up to 800 pixels and a small watermark (gray out × [ datamaker ]). Pro costs €40 per year and adds full-resolution exports without watermark, changing the colour of highlighted elements, and saved style presets.

### Can I install gray out as an app?
Yes. In Chrome or Edge, click Install app at the top of this page or the install icon in the address bar; it then opens in its own window from your desktop, Dock or Start menu, and also works offline. In Safari on a Mac choose File → Add to Dock; on an iPhone or iPad tap Share → Add to Home Screen. On Android use the browser menu → Install app.
