SVG Viewer: a practical guide

Sanitize, preview, and clean SVG locally. That single sentence is most of what SVG Viewer does—the rest is knowing when to reach for it, which inputs cause trouble, and how it fits alongside the other utilities in the same category.

When SVG Viewer is the right tool

Image chores are a short pipeline, and each tool here handles one stage of it well.

• Inspect icons before committing.
• Clean SVG exports from design tools.
• Verify untrusted SVG snippets safely.
• Shrink simple markup for embeds.

Getting a reliable result

Crop before resizing and resize before compressing, so the encoder only works on pixels you intend to ship. Keep a lossless master and export delivery copies from it, since repeatedly re-saving a lossy file compounds the damage.

• Always sanitize before previewing unknown SVG.
• Keep a master copy before optimize.
• Prefer inline SVG only after review.

Mistakes that waste time

• Assuming optimize equals full SVGO.
• Embedding unsanitized SVG in HTML.
• Expecting external font URLs to load offline.
• Ignoring stripped-handler warnings.

Privacy and local processing

Images are decoded and processed in your browser with Canvas APIs, and published size limits protect low-memory devices. Files are never uploaded.
