Export

Let readers download any page as a PDF or EPUB.

Blume can add an Export action to the page actions beneath the table of contents, letting readers save the page they’re on as a PDF or an EPUB. It’s off by default and entirely client-side — no server, and static builds stay static.

Enable it

Turn on both formats with a single toggle:

export: true,

To offer just one format, pass an object instead:

export: {
  pdf: true,
  epub: false,
},

Any format you omit (or set to false) is left out of the menu. With both off — the default — the Export action doesn’t appear at all.

PDF

Export to PDF opens your browser’s print dialog with a print stylesheet that strips the site chrome — header, sidebars, navigation — down to just the article. Choose Save as PDF to finish.

Because it prints the live, fully-styled page, the result keeps crisp, selectable text, real fonts, and syntax-highlighted code. It needs no dependencies and works the same in dev, in production, and on static hosts.

EPUB

Export to EPUB generates a self-contained .epub of the current page in the browser and downloads it — ready for Apple Books, Calibre, or any e-reader. The generator is loaded only when a reader clicks Export, so it never weighs down the rest of your site.

To keep the file readable on a device with no stylesheet or JavaScript of its own, Blume rewrites the page into clean, standalone HTML: syntax-highlighted code becomes plain monospace, decorative icons and copy buttons are dropped, and a built-in e-reader stylesheet handles spacing, code blocks, and tables.

What gets exported

Both formats export the single page a reader is viewing — not the whole site — which matches where the action lives, beneath that page’s table of contents.
