SVG (Scalable Vector Graphics) is the web standard for resolution-independent graphics. An SVG file contains a mathematical description of shapes, paths, and text — not pixels. It can be scaled to any size without quality loss. Converting an SVG to PDF embeds these shapes in a printable, archivable format that renders correctly at any print resolution.
Choosing the right renderer
SVG-to-PDF conversion quality depends entirely on the rendering engine. The most common choices are a web browser engine (Chromium, WebKit, Gecko) or a desktop application engine (LibreOffice Draw, Inkscape).
Browser engines produce the best SVG output because SVG is a web standard — Chromium's SVG renderer is the reference implementation maintained by the Chrome team and tested against the W3C SVG test suite. CSS properties defined in the SVG's <style> block are handled correctly, including CSS variables, calc(), and modern colour formats. SVG filters (blur, drop-shadow, feColorMatrix) are rendered accurately. Text rendered with web fonts embedded as base64 data URIs is preserved.
LibreOffice Draw has partial SVG support. It handles simple SVGs correctly but misses portions of the CSS property set, some filter types, and certain font rendering subtleties. For complex SVGs created by Illustrator, Figma, or Sketch, LibreOffice output often has rendering differences.
Using Filum's SVG to PDF tool
Filum's SVG to PDF tool uses Chromium (via Gotenberg, running on a secure server) to render the SVG and export it as PDF. The SVG is embedded in a minimal HTML wrapper and rendered by the same Chromium engine that powers Chrome — the highest-fidelity option available for web-standard SVG.
The file is uploaded over an encrypted connection, rendered, and immediately deleted. No account is required. Conversion typically takes 5–12 seconds.
Self-contained SVGs and external resources
SVG files can reference external resources: fonts loaded via @import or <link>, raster images linked with <image href="path/to/image.png">, and CSS files. In a server environment, these external references cannot be resolved — the conversion server has no access to your local file system or to external URLs that might be protected.
The solution is to make your SVG self-contained before converting. In Inkscape, use File → Clean Up Document and ensure linked images are embedded (Edit → Images → Embed All Images). In Figma and Sketch, SVG exports are already self-contained by default — embedded fonts are converted to paths. In Illustrator, use Save As → SVG with Embed option.
SVG output size and PDF dimensions
The output PDF is sized to A4 by default (210 × 297 mm). The SVG content is scaled to fill the A4 page width. If your SVG has specific width and height attributes or a viewBox, the content is scaled proportionally to fit.
For print work where exact dimensions matter, set the width and height attributes in your SVG in absolute units before converting. An SVG with width="210mm" height="297mm" will render precisely at A4 dimensions in the output PDF.
