<story><title>Local PDF Tools – Powered by WebAssembly</title><url>https://localpdf.tech/</url></story><parent_chain></parent_chain><comment><author>svat</author><text>Last year I wrote a couple of similar &amp;quot;local&amp;quot; PDF tools that run in the browser with no network requests. Each is just a single HTML file that will work offline:&lt;p&gt;- &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;shreevatsa.net&amp;#x2F;pdf-pages&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;shreevatsa.net&amp;#x2F;pdf-pages&amp;#x2F;&lt;/a&gt; is for extracting pages, inserting blank pages, duplicating or reversing pages, etc.&lt;p&gt;- &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;shreevatsa.net&amp;#x2F;pdf-unspread&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;shreevatsa.net&amp;#x2F;pdf-unspread&amp;#x2F;&lt;/a&gt; is for splitting a PDF&amp;#x27;s &amp;quot;wide&amp;quot; pages (consisting of two-page spreads) in the middle.&lt;p&gt;- &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;shreevatsa.net&amp;#x2F;mobius-print&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;shreevatsa.net&amp;#x2F;mobius-print&amp;#x2F;&lt;/a&gt; is the earliest of these, and written for a niche use-case: &amp;quot;Möbius printing&amp;quot; of pages, which is printing out an article&amp;#x2F;paper two-sided in a really interesting order. (I&amp;#x27;ve tried it and love it.)&lt;p&gt;These don&amp;#x27;t use WebAssembly, but just use the excellent &amp;quot;pdf-lib&amp;quot; JS library. To keep the file self-contained, I put the whole minified source into a &amp;lt;script&amp;gt; tag at the bottom of the (otherwise hand-written) HTML file.</text></comment>
