Here's the core pattern.</p> <p>The Canvas API handles SVG rendering natively—you parse the SVG string, load it as an image, then draw it to a canvas at any<br> resolution:</p> <p>const svgBlob = new Blob([svgString], { type: 'image/svg+xml' });<br> const url = URL.createObjectURL(svgBlob);<br> const img = new Image();<br> img.onload = () =&gt; {<br> const canvas = document.createElement('canvas');<br> canvas.width = img.naturalWidth * scale;<br> canvas.height = img.naturalHeight * scale;<br> const ctx = canvas.getContext('2d');<br> ctx.drawImage(img, 0, 0, canvas.width, canvas.height);<br> canvas.toBlob(blob =&gt; {<br> const downloadUrl = URL.createObjectURL(blob);<br> });<br> };<br> img.src = url;</p> <p>Why this works offline too</p> <p>Once the page is loaded, all processing runs in the browser tab. No server round-trips. Turn off your WiFi and it still converts.</p> <p>Two gotchas</p> <ol> <li>External fonts in SVGs won't render. If your SVG uses <a class="mentioned-user" href="https://dev.to/import">@import</a> for fonts, embed them as base64 first.</li> <li>Canvas has a max size. Most browsers cap at 16,384×16,384px. Enough for 8K at 2x.</li> </ol> api javascript tutorial webdev
