An SVG editor lets you open, modify, and optimize SVG files directly in your browser — no Illustrator or Inkscape install needed. Useful for tweaking icons, recoloring graphics, optimizing file size, or learning how SVG markup works.
This guide covers SVG basics, common edits, optimization, and when to use SVG vs PNG.

SVG Basics
SVG (Scalable Vector Graphics) is XML-based. Unlike PNG/JPG (raster pixels), SVG describes shapes with paths and primitives:
<svg viewBox="0 0 100 100">
<circle cx="50" cy="50" r="40" fill="blue" />
<path d="M10 10 L90 90" stroke="red" stroke-width="2" />
</svg>Benefits: infinite scaling, small file size for simple graphics, CSS-stylable, accessible.
Common SVG Elements
| Element | Use |
|---|---|
| <circle> | Circles (cx, cy, r) |
| <rect> | Rectangles (x, y, width, height) |
| <path> | Any custom shape (d attribute) |
| <line> | Straight lines |
| <polygon> | Multi-point shapes |
| <text> | Text elements |
| <g> | Groups (transforms apply to all children) |
| <defs> | Reusable definitions (gradients, patterns) |
| <use> | Reference defined elements |
Common Edits
- Change fill color — Replace
fill="red"with new color. - Resize — Modify viewBox or width/height.
- Recolor entire icon — Replace all fill values, or use CSS
fill: currentColor. - Combine multiple SVGs — Place under one parent
<g>. - Apply stroke — Add
strokeandstroke-widthattributes. - Make responsive — Remove width/height, keep viewBox.
SVG Optimization
Designers export bloated SVGs from Illustrator/Figma. Common bloat:
- Editor-specific metadata (Sketch, Adobe namespaces)
- Unnecessary precision (10 decimal places)
- Hidden / empty elements
- Inline styles that could be attributes
- Duplicate gradients / definitions
SVGO (the underlying tool most editors use) can strip 50-80% of an SVG's size without visual difference. Always optimize before shipping.
SVG vs PNG — When to Use Which
| Use Case | Best Format |
|---|---|
| Logo | SVG |
| Icon | SVG |
| Illustration (simple) | SVG |
| Photograph | JPG / WebP |
| Complex illustration | PNG / WebP |
| UI element with hover/animation | SVG |
| Print at any size | SVG |

Frequently Asked Questions
How do I change the color of an entire SVG icon?+−
Set fill="currentColor" on all paths and control color via CSS color property of the parent.
Why is my Figma-exported SVG so big?+−
Figma adds editor metadata. Run through an optimizer to drop 50-80% of size.
Can I animate SVG?+−
Yes — with CSS transitions, SMIL animation, or JS libraries like GSAP.
Are SVGs responsive?+−
Yes — remove width/height attributes and keep viewBox. Then scale via CSS.
Are SVGs SEO-friendly?+−
Yes — text inside SVG is crawlable, and properly tagged SVGs are indexed in image search.
