🔒 Every tool runs in your browser — the files and values you enter are never uploaded to any server. How it works

Charts & Design

Turn a few lines of data into a clean chart and download it as a crisp PNG or an editable SVG — bar, line, pie, donut, funnel, radar and waterfall. Style it with ten professional fonts, your own text and chart colours and a transparent background. Everything is drawn in your browser, so the numbers you paste are never uploaded.

Make charts in the browser, not the cloud

Most online chart makers ask you to paste your figures into someone else's server, then hand back an image — often watermarked, behind a sign-up, or capped until you pay. That trade never made sense for a job the browser can do itself. These chart makers draw everything with SVG on your own device: paste “label, value” lines straight from a spreadsheet, pick a color palette, add a title, and download a sharp 2× PNG or a vector SVG you can edit in Figma or Illustrator.

Because nothing is uploaded, they're safe for private, unpublished or sensitive numbers, and they keep working offline once the page has loaded. For color palettes and contrast, see the Color Tools; for exact data crunching, the Statistics tools.

Frequently asked questions

How can a chart maker work without uploading my data?

The charts are drawn with SVG directly in your browser from the numbers you paste, and the PNG export renders that SVG onto a canvas locally. No server is involved, so your data never leaves your device and the tools work offline.

Can I download the charts as PNG and SVG?

Yes — every chart maker exports a crisp 2× PNG for slides and documents, and an editable, infinitely scalable SVG for design tools like Figma, Illustrator and Inkscape.

Is there a watermark or sign-up?

Neither. There is no account, no watermark and no limit — just paste your data, style it and download.

Can I change the font and colours?

Yes. Every chart maker has ten professional fonts (Inter, Roboto, Montserrat, Lato, Oswald, Playfair Display, Merriweather, Lora, Roboto Mono and your system UI font), a text-size slider, a text colour picker, five colour palettes plus a fully custom palette, and a background colour or transparent background.

Will the font survive the download?

Yes — the font is embedded directly into the exported SVG and PNG, so the chart looks identical on any device, even one that does not have that font installed. The fonts are self-hosted, so nothing is ever requested from a third-party CDN.

Which chart type should I use?

Use a bar chart to compare independent categories, a line chart to show a trend over time or a sequence, and a pie or donut chart to show parts of a single whole.
