Can BuildVu output a single file?

v2025.10

Yes. BuildVu’s singlefile mode produces a single self-contained HTML file.

Singlefile mode

Singlefile mode (BuildVu-HTML only) embeds every page, and all of its assets, within one HTML file — so no separate asset files are produced.

Consider performance before using singlefile mode. PDFs are random-access, and the IDRViewer mirrors this by loading pages on demand. Singlefile mode loads the entire document at once, so large or complex documents can be slow to load and may hang or crash the browser (especially on mobile). Use it only for small documents, or workflows where the output isn’t loaded in a browser.

Embedding assets in other modes

In idrviewer or content view modes, BuildVu writes each page as a separate file, with other assets like fonts and images also externally referenced. You can embed some of them instead to reduce the file count (in singlefile mode this is automatic, so there’s nothing to set):

We recommend against embedding fonts as Base64 in these modes: it forces duplicate copies of fonts across pages and prevents deduplication, increasing file size and slowing loading (see Included Fonts for details). Singlefile mode deduplicates fonts properly, which is why it embeds them by default.
