A bar graph is the fastest way to compare quantities across categories: sales by quarter, votes by candidate, hours by project. This bar graph maker gives you a clean, presentation-ready chart without installing software, creating an account, or fighting with spreadsheet styling.
Everything happens in your browser. Your data is never uploaded to a server, which makes this tool safe to use even for confidential numbers from work or school.
How to make a bar graph online
- Add your data. Type category names and values into the table, or copy cells in Excel or Google Sheets and paste them directly into the editor; headers are detected automatically.
- Shape the graph. Add more series with “+ Series” for grouped bars, or flip on “Stacked” to pile series on top of each other. Switch to horizontal bars anytime with one click.
- Make it yours. Pick one of eight color palettes, choose a light, cream, or dark canvas, add a title and axis labels, and toggle value labels if you want exact numbers on the chart.
- Download or share. Export your bar graph as a PNG for slides and documents, as an SVG for perfect scaling, copy it straight to your clipboard, or copy a share link that contains the whole chart.
When should you use a bar graph?
Bar graphs shine when you compare discrete categories: products, teams, countries, months treated as separate buckets. The length of each bar maps directly to its value, which is the single easiest visual comparison for the human eye.
Use grouped bars when you compare two or three series side by side (this year vs last year), and stacked bars when the total matters as much as its parts (total revenue split by product line). If your categories have long names (survey answers, country names), switch to a horizontal bar chart so the labels stay readable.
If you are tracking a continuous trend over many time points, a line graph usually tells that story better than a forest of bars.
Quick tips for a chart people trust
- Start your value axis at zero: bar lengths are the message, and a truncated axis distorts them.
- Sort categories by value when the order isn’t meaningful (alphabetical order rarely is).
- Keep it to five series or fewer; beyond that, grouped bars become hard to read.
- Use one strong color for a single series instead of rainbow bars: color should mean something.
Frequently asked questions
Is this bar graph maker really free?
Yes. Every feature on this page (unlimited charts, every palette, PNG, SVG and clipboard export) is free and requires no account. There is no watermark you can’t remove: the small graphmint.app caption can be switched off in the Details panel.
Can I paste data from Excel or Google Sheets?
Yes. Select your cells in Excel, Google Sheets or Numbers, copy them, click anywhere in the data table and paste. Column headers become series names and the first column becomes your category labels automatically.
How do I make a grouped or stacked bar chart?
Add a second column with the “+ Series” button to get grouped bars automatically. To stack them instead, open the Style tab and turn on the “Stacked” toggle. Value labels then show the total of each stack.
What file formats can I download?
PNG at 2× resolution for crisp slides and documents, and SVG for a vector file you can scale to any size or edit in Figma, Illustrator or Inkscape. You can also copy the chart to your clipboard and paste it straight into PowerPoint, Word or Slack.
Is my data uploaded anywhere?
No. The chart is rendered entirely in your browser and your numbers never leave your device. A share link encodes the chart data inside the link itself, so nothing is stored on a server either.
