About SVG Optimizer Online — Minify & Compress (SVGO)
SVG files exported from design tools are full of overhead — editor metadata, comments, hidden layers, redundant attributes, and coordinates carried to a dozen decimal places. This SVG optimizer strips all of that away, shrinking icons and illustrations without changing how they look. Smaller SVGs mean faster page loads, lighter component bundles, and cleaner markup to paste into your code.
Powered by SVGO, the industry-standard SVG optimization engine, it removes metadata and comments, rounds numeric precision, collapses useless groups, and minifies the result — typically cutting file size by 30–70%. A live byte counter shows exactly how much you saved on every run.
Everything happens locally in your browser. Your SVG is never uploaded to a server, so you can safely optimize proprietary artwork and logos completely offline.
Features
- Minify SVG with the SVGO engine — the same optimizer used by build tools
- Strips metadata, comments, and editor cruft; rounds coordinate precision
- Multipass option squeezes out extra bytes; prettify keeps output readable
- Live bytes-saved report and percentage; runs entirely offline
How to use
- Paste or drop your SVG markup into the input pane.
- Toggle Multipass for maximum compression, or Prettify for readable output.
- Click Optimize and watch the original → optimized byte savings.
- Copy the optimized SVG from the output pane and drop it into your project.
Frequently asked questions
Will optimizing change how my SVG looks?
No. The optimizer only removes data that does not affect rendering — metadata, comments, redundant attributes — and rounds precision to a safe level. The visual result is identical, just lighter.
What does the Multipass option do?
Multipass runs the optimization pipeline repeatedly until the file stops getting smaller. Some reductions only become possible after an earlier pass simplifies the markup, so multipass often shaves off a few extra bytes.
When should I use Prettify instead of minifying?
Leave Prettify off for production assets where the smallest size wins. Turn it on when you want a clean, human-readable, indented SVG to commit to source control or inspect by hand.
How much can SVGO reduce file size, and is it lossless?
Optimization is visually lossless — it only drops data that does not affect rendering — yet typically cuts file size by 30–70%, depending on how much editor metadata and excess precision the source carried. Design-tool exports usually shrink the most; already-minified SVGs change little.
Is my SVG uploaded anywhere?
No. All optimization runs locally in your browser using SVGO. Your markup never leaves your device, so it is safe for confidential logos and artwork and works fully offline.
