The Infographic Maker is 100% client-side. Each block — a header, a stat callout, a chart, an icon row, a timeline, a comparison, a quote, an image or a footer — is a plain typed object in the page, and a pure engine flattens the whole document into one list of drawing operations. That same op list is replayed to an in-browser SVG for the live preview and to an HTML5 canvas for the PNG export, so nothing is ever sent anywhere. When you upload an image it is read straight into a local data URL and composited on-device; it never leaves your computer. There is no analytics, no tracking and no CDN in the processing path; the only optional network use is consent-gated ads. The tool works offline once cached, and closing the tab discards anything you did not export.

Charts are built from the numbers you enter, not from an external source. In a chart section you pick the type (a vertical bar chart, a pie or a donut), then add rows of label + value and optionally a colour per slice or bar. The engine reuses the same charting maths as the Chart & Graph Maker: it computes a human-friendly “nice number” value axis (rounded to 1 / 2 / 5 multiples) for bars, proportional wedges for pie and donut charts, and a legend with each slice’s percentage. Everything is drawn as vector shapes, so it stays crisp in the SVG export and at any PNG scale. There is no CSV/Excel import, trendline fitting or live-data connection — it is deliberately a fast, private, type-the-numbers chart for a poster, not a full analytics tool.

Good infographics follow four pillars: visual hierarchy, consistent colour, restrained typography and white space. Make your headline and the single most important number the biggest elements so the eye lands there first, then let stats, charts and supporting text descend in size. Assign each colour a role and reuse it — the tool’s six themes already give you a coherent three-to-five-colour palette and a matching font. Do not rely on colour alone to convey meaning (roughly 8% of men have a colour-vision deficiency), so pair colour with labels and icons, and keep text contrast readable (WCAG asks for about 4.5:1 for body text). Finally, tell one story per graphic: a header to frame it, a few stats or a chart for evidence, maybe a timeline or comparison, and a source line — which is exactly the set of section blocks this maker provides.

Because the same renderer-agnostic op list drives both the preview and the export, the file you download matches the preview exactly (true WYSIWYG). For raster output, choose a PNG scale of 1×, 2× or 3× — at 2× an 800-px-wide canvas exports at 1600 px, which is sharp for web and social. For a resolution-independent file, export SVG: it is vector, so it stays crisp at any size and embeds any uploaded image as a data URL. One caveat: text renders with the fonts installed on the viewing device (the tool uses portable system-font stacks that work fully offline), so someone opening your SVG on another machine may see slightly different text metrics, and canvas text can vary a hair between browsers — always glance at the exported PNG before publishing.
