High-fidelity SVG Viewer, Inspector, and Vector Optimizer.
Preview, inspect SVG DOM layers, test responsive scaling, swap color palettes in bulk, and optimize code for production — 100% private in your browser.
DOMParser is only available in browser
JSONGlow's SVG Viewer is a free, in-browser studio for previewing, inspecting, color-modifying, and optimizing SVG vector files with zero server uploads.
Interactive Vector Studio
Comprehensive SVG inspection, color tweaking, and optimization.
Scalable Vector Graphics (SVG) are the gold standard for web icons, logos, illustrations, and UI graphics. However, working with raw SVG files often involves debugging malformed viewBox coordinates, cleaning bloated editor metadata from Figma or Illustrator, and testing rendering across different backgrounds.
JSONGlow's SVG Viewer provides an all-in-one studio environment. Pan and zoom across complex vector artwork, toggle between transparent checkerboard and dark/light backdrops, inspect the full DOM hierarchy of paths and groups, and edit raw XML with instant live updates.
With built-in bulk color replacement and SVGO-style optimization (stripping metadata, comments, and rounding coordinate decimals), you can prepare clean, production-ready assets for modern web applications.
Workflow Guide
How to view and optimize SVG vectors in 3 steps
Input your vector graphic
Drag and drop an .svg file, paste raw SVG XML code or Data URI, or pick from our curated geometric and icon samples.
Explore layers & swap colors
Use the interactive pan/zoom canvas, inspect SVG DOM node hierarchies, swap color swatches in bulk, or optimize markup to reduce file size.
Download or copy code
Download cleaned vector .svg, export high-definition raster PNG/WebP (1x, 2x, 4x Retina), or copy React JSX code and Data URIs.
Core Capabilities
All-in-one SVG developer studio
Interactive Canvas Pan & Zoom
Smoothly navigate complex illustrations with zoom controls up to 800%, pan navigation, and 1:1 resets.
Bulk Color Swapper

Live XML Code Editor
Real-time bidirectional editing with instant rendering, syntax formatting, and error diagnostics.
SVGO-Style Vector Optimizer
Clean Figma/Illustrator metadata, strip comments, remove empty groups, and reduce file size by up to 70%.
High-Res PNG & WebP Export
Export vector SVGs to crisp raster PNGs up to 4x Ultra-HD resolution with transparent or dark backgrounds.
React Component Generation
Convert any SVG to a clean React TypeScript component (TSX) with camelCase attributes and {...props}.
Frequently Asked Questions
Common questions answered.
Need more help? Our tools execute entirely in your browser without transmitting any payload to remote servers.
Can I inspect and edit SVG code in real time?+
Yes! The live SVG XML editor updates the interactive canvas immediately as you type. You can format/prettify XML code or inspect individual layers, paths, rects, and gradients in the hierarchy panel.
How does the bulk Color Swapper feature work?+
The tool scans every fill, stroke, stop-color, and inline CSS hex color in your SVG. You can select any color and pick a replacement to swap it across the entire graphic with one click.
How does the SVG Optimizer reduce file size?+
The optimizer removes editor metadata (from Figma, Adobe Illustrator, Inkscape, Sketch), strips XML comments, removes unused namespaces/empty groups, and rounds path coordinate decimal precision to save 30% to 70% in file size.
Can I convert and export SVG to PNG or WebP at high resolution?+
Yes! You can render and export your vector SVG as high-resolution PNG (up to 4x Ultra-HD), WebP, or JPEG with transparent or custom background colors.
Is my SVG code kept private?+
100% private. All rendering, color parsing, and optimization happen strictly inside your browser sandbox via JavaScript and the HTML5 Canvas API.
