Online SVG Optimizer - Compress and Clean SVG Files
Why optimize SVG files?
SVGs exported from design tools such as Illustrator, Figma and Sketch carry a lot of data the web does not need: editor metadata, generated IDs, redundant styles, excessive decimal precision, hidden elements and inefficient structure. A 50 KB SVG can often drop to 10 KB with no visual change. Smaller SVGs mean faster loading, lower bandwidth use and quicker parsing of the SVG DOM. For icons repeated hundreds of times across an application, optimization matters even more.
SVG optimization techniques
Optimization covers several passes: removing comments, metadata and editor-specific elements; dropping attributes that already hold their default value; collapsing unnecessary groups; simplifying paths by merging commands; reducing decimal precision, since three decimals is usually plenty; converting inline styles to shorter attributes; deleting empty or invisible elements; merging paths where it is safe; and stripping unnecessary whitespace and line breaks. Tools such as SVGO automate this through configurable plugins. This tool applies the safe optimizations that never change the rendered appearance.
Manual versus automatic optimization
Automatic optimization is safe for most files, but aggressive passes can break complex SVGs: merging paths can break CSS animations, removing IDs breaks internal references, and cleaning the viewBox can change sizing. The recommendation is to run a conservative automatic pass and then review critical SVGs by hand. Simple icons tolerate aggressive optimization well. Complex illustrations with gradients, masks and filters deserve caution. Always compare appearance and size before and after.
If you work with this tool, you will probably also find these useful CSS Minifier, JavaScript Minifier, Gradient Generator, Flexbox Generator.
Frequently asked questions
Can optimization break my SVG?
Conservative passes such as stripping metadata and reducing decimals are safe. Aggressive passes such as merging paths or removing IDs can break CSS and JavaScript animations that reference those IDs, masks and clips, and <use> references to reusable symbols. This tool applies the safe optimizations, but always check the result visually.
How much smaller does an SVG usually get?
It depends on the source. Illustrator exports typically shrink by 50 to 80% because they carry a lot of metadata. Figma produces cleaner output, so 20 to 40% is typical. Already optimized or hand-written SVGs may only drop 5 to 10%. The biggest gains come from files with many complex paths where decimal precision can be cut substantially.
Should I optimize SVGs used as <img> as well as inline ones?
Always optimize both. For an <img src="icon.svg">, file size drives the download. For inline SVG in HTML, size drives the document weight and parse time. Inline SVGs have the extra benefit that you can style them with CSS and manipulate them with JavaScript, but they inflate the initial HTML, which makes optimization even more valuable.
Can I undo the optimization if something goes wrong?
Optimization is destructive: whatever was removed cannot be recovered. Always keep the original unoptimized files in your repository or design system and optimize only during the build or deploy step. Tools such as SVGO integrate into a CI/CD pipeline so files are optimized automatically without touching the sources.
