This free chart maker lets you create professional-quality pie charts, bar charts, and line charts directly in your browser without installing any software or uploading your data to a server. Unlike services such as Google Charts, Canva, or ChartGo that require accounts or process your data on their servers, this tool is 100% client-side — your data never leaves your device. Simply enter your labels and values in the sidebar table, choose a chart type, and the chart renders instantly on an HTML5 Canvas. Customise your chart with a title, toggle the legend, data labels, and grid lines on or off, and assign custom colours to each data point. When you are satisfied with the result, export your chart as a high-resolution PNG image or a scalable SVG vector file suitable for presentations, reports, and publications. You can also copy the chart directly to your clipboard for instant pasting into documents, emails, or chat apps. Whether you are a student creating a report, a business analyst preparing a presentation, a teacher building educational materials, or a developer needing a quick data visualisation, this tool gives you beautiful charts in seconds with zero friction. No account creation, no cloud dependencies, no watermarks, no ads — just fast, private, professional charts. One of 63+ free browser-based tools at jasperbernaers.com.
This chart maker supports three core chart types: Pie charts for showing proportional data and percentage breakdowns; Bar charts for comparing values across categories with vertical bars; and Line charts for visualising trends and changes over time. Each chart type is rendered using the HTML5 Canvas API with smooth anti-aliased graphics, proper colour contrast, and clear labelling. All three types support custom colours per data point, optional value labels, legends, and grid lines where applicable.
Completely private. This chart maker runs 100% in your browser using client-side JavaScript and the HTML5 Canvas API. Your data is entered directly into the browser and rendered locally — no data is ever sent to any server. There are no cookies tracking your charts, no cloud storage, no account creation, and no server-side processing. When you close the tab, your data is gone. This makes it safe for confidential business data, financial figures, research data, and any sensitive information that you would not want exposed to third-party services.
Data is entered in a simple table in the sidebar with three columns: Label (the name for each data point), Value (the numerical value), and Color (a colour picker for customisation). Click “Add row” to add new data points or click the × button to remove a row. The chart updates in real-time as you type, so you get instant visual feedback. Use the “Load sample data” button to see an example chart and understand the data format before entering your own numbers.
Three export options are available: Download PNG saves a high-resolution raster image suitable for web use, social media, and documents; Download SVG saves a scalable vector file that can be resized without losing quality — ideal for print publications, presentations, and professional reports; Copy to clipboard places the chart image directly on your clipboard so you can paste it into Google Docs, Microsoft Office, email clients, Slack, or any application that accepts pasted images. All exports are generated entirely in your browser with no server round-trip.
Absolutely. The charts are rendered with professional-quality anti-aliased graphics, clean typography, and proper colour contrast. The SVG export is particularly well-suited for professional use because vector graphics scale to any size without pixelation — whether you are projecting on a conference room screen, printing in a PDF report, or embedding in a slide deck. The charts have a clean, minimal aesthetic that works well in both corporate and academic contexts.
