Introduction
Every six months I get the same request — take this PDF infographic and make it interactive, but please not on a platform that charges per view. The good news is that PDFs are mostly vector data, and vector data converts cleanly into SVG, which the browser already animates and links. The bad news is that the conversion is not one button. There are three real paths (SVG, HTML, image-with-map), they each preserve different parts of the source, and the right one depends on whether your infographic is mostly shapes, mostly text, or mostly a single hero image. Here is the practical decision tree, with the bits of glue code that turn a static PDF into something with hover, tooltips, and anchor jumps.
Vocabulary, quickly
| Term | Meaning |
|---|---|
| Interactive infographic | A visual with hover, tooltips, anchor jumps, and embedded media — usually HTML/SVG |
| PDF -> SVG | Vector pipeline that preserves shape geometry, fonts, and color |
| PDF -> PNG + map | Raster image plus a clickable region map; simplest path, lowest fidelity |
| PDF -> HTML | Reflow-aware extraction that yields styled paragraphs and tables |
| Anchor jumps | In-page hash links that scroll to a specific element |
| Tooltip layer | Hover-revealed text bound to a region or element |
| Embed | YouTube, audio, or iframe placed inside the rendered output |
Step by step
- Decide the dominant content type. Shapes and icons want SVG. Heavy text wants HTML. A single hero image wants image-plus-map. Pick once; converting between mid-project is painful.
- Embed fonts in the source PDF. Open the source, choose Export with subset fonts embedded, and re-save. The conversion inherits whatever the renderer sees, so missing embeds become substitution failures.
- Convert via the chosen route. SVG: pdf2svg or Inkscape command-line. HTML: pdftohtml with the -c flag for CSS layout. Image-map: pdftoppm at 200 DPI plus a hand-written area map.
- Open the output and audit it. Are shapes intact? Did text reflow? Did colors shift? Fix at the source-PDF level when possible — conversion-tool flags rarely close gaps on their own.
- Add interactivity layer. For SVG: wrap regions in
<g>with title and a CSS hover. For HTML: use<details>for click-expand or anchor links for jumps. For image-map: standard<area>with href. - Test on three viewports. Phone portrait, tablet landscape, desktop. SVG scales cleanly; image-maps usually do not — be ready to drop a second image and second map at a mobile breakpoint.
- Ship as static files. Drop the result in a static-site host. No backend, no platform fees, no per-view charges. Add basic privacy-friendly analytics if you need engagement data.
Quality checklist before publishing
- Every hover region has a focusable element and an aria-label, so keyboard and screen-reader users can reach the tooltip content.
- Anchor jumps land at the heading, not under the sticky header — set scroll-margin-top on the target.
- Image-map coordinates re-scale with the image; do not hard-code pixel offsets that break on mobile.
- Outbound links open in a new tab only when the user expects it (download links, external references); same-tab is the default for internal jumps.
- Self-host fonts as WOFF2 with font-display: swap so the layout does not jump on slow connections.
- Validate the SVG or HTML once with the W3C validator — broken markup breaks screen readers more often than it breaks the visual layout.

FAQ
- Why bother — can I just upload my PDF to Genially?
- You can, but a Genially upload converts the PDF to a fixed background and asks you to draw interactive zones on top. It is a UI for adding interactivity, not a conversion. If you want hover, tooltips, anchor jumps, and embeds without manual zone-drawing, you need to start from SVG or HTML, which Genially does not produce on import.
- Which conversion route preserves the most fidelity?
- PDF to SVG via Inkscape or pdf2svg preserves vector shapes, fonts (if embedded), and exact color. The output is editable in any vector tool and styles cleanly with CSS. The trade-off: text often renders as path geometry rather than selectable text, which breaks copy-paste and search. For text-heavy infographics, use a PDF-to-HTML tool instead.
- How do I add hover tooltips without a builder app?
- After converting to SVG, wrap each interactive region in a group, give it a title element, and attach a CSS hover rule that reveals a styled tooltip div positioned by JavaScript. About 30 lines of code total. The same pattern works for click-to-expand and anchor jumps. No platform lock-in, deploys as static files.
- Will fonts look right after the conversion?
- Only if the source PDF embedded its fonts. Many corporate PDFs subset fonts or substitute Helvetica at render time, and the converted SVG inherits whatever the renderer saw. Embed fonts in the source PDF before conversion (or self-host the WOFF2 in the output HTML) — otherwise the browser renders a generic substitute and the layout reflows.
- Can I keep PDF links in the converted output?
- PDF hyperlinks survive PDF-to-HTML conversion but usually do NOT survive PDF-to-SVG. If your infographic relies on outbound links, convert to HTML first and overlay the SVG visuals, or run a post-process script that maps PDF annotation rectangles to <a> tags in the SVG.
- What is the lightest-weight option for a one-page infographic?
- Export the PDF page as a PNG at 2x resolution, then write a 20-line HTML page with an <img> and a series of <a> tags positioned via an absolute <area> map. Zero JavaScript, zero platform fees, loads instantly. The trade-off is no hover-reveal — only click. For most internal infographics this is enough.
