SVG to Interactive HTML Viewer

Turn any SVG into a standalone, self-contained HTML file that anyone can drag, pan, and zoom — like Google Maps. Upload an SVG, preview it, then download a single HTML file that works offline with no server, no CDN, and no dependencies. Everything runs locally; your file never leaves your device.

Works with SVGs from draw.io, Excalidraw, Figma, Graphviz, D3.js, and more. Processed locally — never uploaded.

How to Convert SVG to Interactive HTML

Upload your SVG — click the upload zone, drag and drop a .svg file, or paste SVG code directly.
Preview and interact — drag to pan, scroll (or pinch) to zoom, and double-click to reset. Try it before you download.
Pick a background — choose White, Light Gray, or Dark so your diagram stays readable.
Download the HTML — click "Download Standalone HTML" to get one self-contained file.
Open and share — the file works in any browser with no internet connection. Send it to anyone; they can pan and zoom immediately.

Features

Standalone & self-contained — the downloaded file inlines the SVG and all viewer code into one HTML file. No CDN, no external scripts, works fully offline.
Drag to pan, scroll to zoom — a smooth, Google Maps–style navigation experience for large diagrams.
Double-click to reset — instantly refit the diagram to the screen.
Touch & pinch support — works on phones and tablets with one-finger pan and two-finger pinch zoom.
Tiny output — the viewer engine is just a few kilobytes, so your HTML stays nearly as small as the original SVG.
Privacy-first — your SVG is processed entirely in your browser using JavaScript. No upload to any server, no signup required.
Any SVG source — draw.io, Excalidraw, Figma, Graphviz, D3.js, Mermaid, and hand-written SVGs all work.

FAQ

Why can't I just open the SVG in my browser?

Your browser can display an SVG, but it can't interactively view it. Opening a large diagram directly shows the whole thing at once (labels too small to read), and scrolling just scrolls the page — there's no smooth pan or zoom. This tool wraps your SVG in a viewer that adds drag-to-pan, scroll-to-zoom, and double-click-to-reset, then packages it as a single HTML file.

Does the downloaded HTML file need an internet connection?

No. The generated file is fully self-contained: the SVG content, the styles, and the pan/zoom JavaScript are all inlined. You can open it offline, from a USB drive, or from an email attachment, and it will work in any modern browser. This is a key difference from other tools that rely on CDN-hosted libraries.

Is my SVG uploaded to a server?

No. Everything happens locally in your browser using JavaScript. Your file is read by the page, rendered in the preview, and written into the downloaded HTML — all on your device. You can verify this by disconnecting your internet after the page loads; the tool keeps working.

Which SVG sources are supported?

Any valid SVG works, including files exported from draw.io, Excalidraw, Figma, Lucidchart, Graphviz, Mermaid, PlantUML, and D3.js. The tool automatically detects the diagram's size from its viewBox or width/height attributes and fits it to the screen on load.

What about images or fonts referenced inside my SVG?

Text, shapes, paths, gradients, and embedded (data-URI) images are preserved. However, an SVG that links to external images (e.g. <image href="https://…">) or external web fonts will still need an internet connection to show those parts, because they are not part of the SVG file itself. Most diagram tools export self-contained SVGs, so this is rarely an issue.

Can I customize the viewer (zoom speed, limits, colors)?

The MVP currently lets you choose the background color. Options like initial zoom level, min/max zoom limits, and custom toolbar text are on the roadmap. If you need them today, you can open the downloaded HTML in any text editor and tweak the MIN / MAX constants in the inline script.

Is the downloaded file safe to share?

Yes, for SVGs you trust. The generated HTML contains exactly the content of your SVG plus a small viewer script. Note that an SVG is XML that can contain <script> tags, so only generate viewers from SVGs you trust — the same caution you would apply to sharing the original SVG file itself.
