About SVG ViewBox Optimizer
The SVG `viewBox` Optimizer & Coordinate Recalculator computes exact tight-fitting `viewBox="minX minY width height"` bounds, strips redundant `width`/`height` pixel attributes, and recalibrates coordinate systems to make SVGs responsive.
How to Use SVG ViewBox Optimizer
Step 1
Paste your raw SVG code or upload an `.svg` file.
Step 2
Review computed bounding box dimensions and aspect ratio.
Step 3
Inspect the responsive SVG preview canvas.
Step 4
Click "Copy Optimized SVG".
Practical Use Cases for SVG ViewBox Optimizer
Fixing Broken & Clipped SVG Icons
Recalculate `viewBox` coordinates for SVGs exported from Figma or Illustrator that appear cropped, off-center, or tiny inside responsive icon wrappers.
Removing Hardcoded Pixel Dimensions for Responsive CSS Sizing
Strip hardcoded `width="500"` and `height="500"` attributes and establish scalable `viewBox` coordinates for Tailwind `w-6 h-6` styling.
Input & Output Examples
Adding Optimal viewBox to Legacy SVG
`<svg width="100" height="100"><circle cx="50" cy="50" r="40"/></svg>`
`<svg viewBox="0 0 100 100" fill="none" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="40"/></svg>`
Key Features & Performance
- ✓Calculates tight bounding box coordinates from SVG path geometry.
- ✓Normalizes coordinates to origin `(0, 0)` with auto-centering.
- ✓Configures `preserveAspectRatio` (`xMidYMid meet`, `slice`, `none`).
- ✓100% Client-Side memory execution.
- ✓1-Click Copy optimized SVG.
Key Terminology & Definitions
`viewBox` Attribute
An SVG attribute defining the internal user coordinate system and aspect ratio mapping onto the viewport container.
`preserveAspectRatio`
An SVG attribute indicating whether and how the aspect ratio of the viewBox is forced to match the aspect ratio of the viewport.
