What is SVG optimization?

SVG optimization is the process of removing unnecessary data from an SVG file — such as editor metadata, comments, hidden elements, and redundant attributes — to produce a smaller, cleaner file that renders identically in browsers. Optimized SVGs load faster and are easier to work with in code.

Will optimizing my SVG change how it looks?

In most cases, no. This tool only removes data that doesn't affect visual rendering: comments, metadata, empty groups, redundant transforms, and similar overhead. The 'Remove Hidden Elements' and 'Remove viewBox' options can occasionally affect layout in edge cases — disable them if you notice any visual changes.

SVGO (SVG Optimizer) is the industry-standard open-source library for optimizing SVG files. It's used by major tools like Webpack, Vite, and design export pipelines. This tool runs SVGO entirely in your browser — no server required.

Is my SVG uploaded to a server?

No. All optimization happens directly in your browser using the SVGO library compiled to JavaScript. Your SVG code never leaves your device. This tool is 100% private.

Why should I clean IDs in my SVG?

SVG editors like Illustrator and Inkscape generate long, sequential IDs like 'path12345'. Cleaning IDs shortens them to minimal values, reducing file size. This is especially helpful when inlining SVGs in HTML, where conflicting IDs across multiple SVGs can cause rendering bugs.

What does 'Merge Paths' do?

The Merge Paths optimization combines consecutive SVG elements that share the same styling attributes into a single path element. This reduces the number of DOM nodes and can significantly shrink file size for complex illustrations.

Can I paste SVG code directly?

Yes. Click anywhere in the paste area and paste your SVG markup (Ctrl+V or Cmd+V). The optimizer will process it immediately and display the results.

What's the difference between the before and after previews?

The before preview renders your original SVG as-is. The after preview renders the optimized output. Both render identically in nearly all cases, confirming the optimization is safe. You can toggle between them to compare.

How to Optimize an SVG File

1
Open SVG Optimizer
Go to converter.plus/svg-optimizer in any modern browser.
2
Load your SVG
Drop an .svg file onto the upload area, click to browse, or paste raw SVG code into the text area.
3
Choose optimization options
Select which optimizations to apply using the checkboxes. Sensible defaults are pre-selected.
4
Review the results
See the original size, optimized size, and percentage reduction. Use the Before/After toggle to verify the SVG still looks correct.
5
Download or copy
Click Download to save the optimized SVG file, or Copy to grab the raw SVG markup for use in code.

About SVG Optimization

SVG files exported from design tools like Adobe Illustrator, Figma, and Inkscape often contain significant amounts of invisible overhead: editor-specific metadata, long auto-generated IDs, redundant transforms, empty groups, and verbose color values. None of this data affects the final rendering, but it adds to file size and makes the SVG harder to work with in code.

This tool runs SVGO — the industry-standard SVG optimizer — directly in your browser using its browser-compatible build. SVGO is the same library used internally by Vite, Webpack, and most modern web toolchains. Running it here means zero server involvement: your SVG data never leaves your device.

Optimized SVGs are smaller (often 30–70% reduction), easier to inline in HTML, and safer to use across multiple components because cleaned-up IDs eliminate collision bugs. For icon libraries and illustration-heavy sites, SVG optimization is one of the highest-impact, lowest-effort performance wins available.
