SVG Optimizer — Compress & Minify SVG Files
Make SVG files up to 80% smaller with SVGO, the optimizer used by most web build tools — right in your browser. Optimize a whole folder at once, compare before and after pixel by pixel so nothing changes visually, keep IDs for animation, and download a clean file or a ZIP.
How to compress an SVG file
Drop one file or a whole batch, or paste SVG code. Nothing is uploaded.
Safe keeps IDs, groups and shapes for animation; Balanced is the recommended default; Maximum squeezes every byte. Fine-tune decimal precision and individual options any time.
The visual check compares the original and optimized SVG pixel by pixel. Drag the before/after slider, copy the code or a data URI, and download one file or a ZIP.
What the optimizer does
<title> and the viewBox by default so the SVG stays accessible and scalable.Cleaning up AI-generated or traced SVGs?
SVGs from AI image tools, code assistants and auto-tracers are often several times larger than they need to be: coordinates with six or more decimals, invisible shapes, empty groups and repeated styles. Run them through the Balanced or Maximum preset — the visual check confirms the result still looks the same. Need to recolor it afterwards? Send it straight to the SVG Color Changer, or turn it into a CSS background with the Tailwind SVG Encoder.
Frequently asked questions
What does an SVG optimizer do?
It rewrites the SVG code to be as small as possible without changing how it looks: it removes editor metadata and comments, shortens path data and numbers, merges redundant elements and removes hidden shapes. This one uses SVGO, the open-source optimizer used by most web build tools.
Will optimizing change how my SVG looks?
It shouldn’t — and here you can check. After every optimization the tool renders the original and the optimized SVG and compares them pixel by pixel. If anything differs, you see exactly where and can switch to safer settings with one click.
How much smaller will my SVG get?
Files exported from Illustrator, Inkscape, Figma or Sketch typically shrink by 30–80%. AI-generated and auto-traced SVGs, with long decimals and hidden shapes, often shrink the most. Already-optimized icons may only lose a few percent.
Is my SVG uploaded to a server?
No. Optimization runs entirely in your browser — your files never leave your device, and it works offline once the page has loaded.
Can I optimize many SVG files at once?
Yes. Drop up to 50 SVGs at once; every file is optimized with the same settings and you can download them all as a ZIP.
I animate my SVG with CSS or JavaScript. Is it safe to optimize?
Turn on “Keep IDs & classes” and “Keep structure” (or use the Safe preset). That keeps the IDs, classes and groups your code targets while still removing editor bloat and shortening numbers.
What is the difference between the presets?
Safe keeps IDs, groups and shapes and uses 4 decimal places. Balanced is SVGO’s recommended default with 3 decimals and multiple passes. Maximum uses 2 decimals and removes width/height so the SVG scales to its container. You can fine-tune any option.
Does it remove the title for accessibility?
Not by default. The <title> element is how screen readers describe an SVG, so it is kept unless you choose to remove it.
