SVG Optimizer
Optimize SVG markup for free in your browser. Upload or paste SVG, run local SVGO cleanup, preview the result, then copy or download without uploading assets.
SVG Optimizer overview
The SVG Optimizer cleans up SVG markup exported from design tools and reduces file size before production use. You can upload an SVG file or paste markup directly. Options include Multipass, Remove size and Keep formatting. After optimization, the page shows original size, optimized size and savings, plus an embedded preview so you can confirm the visual result before copying or downloading the SVG.
SVGs are common for icons, logos, illustrations and UI graphics. Unoptimized files may contain editor metadata, redundant attributes, empty groups or verbose structures. KitVerse runs SVGO locally in your browser and does not upload the SVG content, which is useful for private brand assets or unreleased product graphics. Use the free tool to clean markup, compare size and save kitverse-optimized.svg for your project.
How to use SVG Optimizer
- 1Click Upload SVG or paste SVG markup into the Input SVG editor.
- 2Enable Multipass when you want a more aggressive cleanup pass.
- 3Enable Remove size if the SVG should scale through CSS or its container.
- 4Enable Keep formatting when readability matters more than the smallest output.
Troubleshooting
Size does not shrink
Already-small SVGs or pretty output may not reduce much.
Disable Keep formatting when the smallest output matters.
Removing dimensions breaks display
SVGs without a valid viewBox may not scale correctly after removing width and height.
Keep dimensions unless a viewBox is present and responsive scaling is needed.
SVG and PNG compared
SVG is ideal for vector graphics, but not every image should be SVG.
| Format | Best content | Strength | Limit |
|---|---|---|---|
| SVG | Icons, logos and simple vector art | Scales cleanly and stays editable | Complex photos or huge paths can be inefficient |
| PNG | Screenshots and transparent bitmaps | Stable pixel rendering | Blurs when enlarged and may be larger |
| Optimized SVG | Production vector assets | Removes redundant code | Preview is still required |
| Pretty SVG | Assets edited by humans | More readable markup | Usually larger than minified output |
SVG Optimizer examples
SVG cleanup
Before
<svg width="240" height="120"><metadata>...</metadata><g><path d="..."/></g></svg>
After
<svg viewBox="0 0 240 120"><path d="..."/></svg>
Actual output depends on the SVG and selected SVGO options.
Use cases
Icon production
Clean design-tool output before shipping front-end assets.
Logo inspection
Preview optimized SVG to ensure brand artwork still looks correct.
Responsive vectors
Remove width/height when the SVG should scale through its container.
FAQ
Is my SVG uploaded?›
No. Reading, optimization, preview and download run locally in your browser.
Can optimization change appearance?›
Default settings are conservative and keep viewBox, but you should preview complex gradients, filters or animations.
What does Multipass do?›
It lets SVGO run additional cleanup passes, which may reduce size further at the cost of more processing time.
When should I remove width and height?›
Use it when the SVG should scale responsively through CSS or its container. Keep dimensions for fixed-size assets.
Does Keep formatting reduce compression?›
Yes. Pretty output is easier to read but usually larger than minified SVG.
Can I optimize multiple SVG files at once?›
The current page handles one SVG at a time.
Why did the optimized SVG get larger?›
Pretty output or an already tiny source can produce a larger result. The page reports increases as well as savings.
Is the SVG optimizer free?›
Yes. It is free and does not require sign-in.
