Stop shipping bloated SVGs. Learn how to configure Adobe Illustrator's export settings to reduce file size, maintain scalability, and ensure CSS compatibility.
SVGO's default preset won't strip editor-specific junk like Inkscape's namespaced attributes. A small custom plugin — using the v3 visitor API — turns SVGO into an SVG hygiene enforcer, not just a minifier.
When you inline many SVGs into one HTML page, duplicate element IDs silently break gradients, clip paths, and masks. This post shows how to enable SVGO’s prefixIds plugin to namespace IDs per file, with a concrete config and verification steps.
Architecture note describing the requirements, design, trust boundaries, operational checks, failure modes, and evolution conditions for SVGO’s removeViewBox plugin.
Learn how to diagnose and fix responsive scaling issues in SVGs caused by SVGO's removeViewBox plugin, including configuration fixes and verification steps.
Enable SVGO’s multipass mode, fine‑tune plugins, and verify that deeper SVG cleanup keeps visual fidelity while shrinking file size by at least 10%.
When preparing SVG assets for low‑traffic web use, designers often rely on Inkscape’s Simplify command (Ctrl+L) to lower node counts and reduce file size. The command applies the Douglas‑Peucker algorithm with a distance threshold that is not exposed as a precise numeric setting in the current UI, making the amount of simplification dependent on the selectio
The goal is to optimize SVG files with svgo while retaining accessibility metadata such as aria-* attributes, role, title, and desc elements. The same preservation behavior should apply whether svgo is invoked through its command-line interface or its Node.js programmatic API. Svgo 3.x uses a different default plugin set than 2.x, and the removeAttrs plugin
