Free SVG Optimizer

Drop the SVG on this page and the optimizer removes editor data, metadata, comments, hidden shapes and extra whitespace. Check the preview and the size saved in the stats bar, then click Download to get the smaller file.

From about 1% to 80% in our sample files, depending on where the file came from. An Inkscape-style logo full of editor data shrank by 80%, while a clean 24 px icon shrank by 1%. Photos embedded inside an SVG do not get any smaller.

Usually not. Shapes, colors and path coordinates are kept as they are. The risk is Remove hidden elements, which deletes shapes set to zero opacity or display none, even if CSS or a script would show them later. Compare the two previews before you download.

Clean IDs is the likely cause. It deletes unused IDs and renames the rest to short ones such as a and b, so CSS or scripts outside the SVG that look for an ID no longer match. If the SVG has its own style or script tag, Clean IDs leaves the IDs alone. Turn Clean IDs off to keep them.

Remove metadata deletes the metadata block. Remove comments deletes code comments. Collapse groups unwraps groups that do nothing. Clean IDs shortens or removes IDs. Remove hidden elements drops invisible shapes and unused definitions. Merge paths joins neighboring paths that share a style.

Yes. The viewBox, width, height, title and desc tags are always kept, so the SVG still scales and has its text label. One catch: Clean IDs removes the ID of a title, which breaks an aria-labelledby link to it. Turn Clean IDs off for those files.

No. Path coordinates are not rounded, so no digit that matters is cut, and colors are not rewritten. Merge paths rewrites the path code when it joins two paths, so 10.000000 can become 10, but the value stays the same. Files with long decimals shrink less here for that reason.

The file is not valid SVG code. The optimizer reads the file as text and stops at broken markup, such as an unclosed tag, and the message names the line and column. Fix that spot in a text editor and add the file again.

Yes. Click Show code diff under the previews to open the original and optimized code side by side. It shows both full files rather than highlighting each change, and the optimized code is minified onto one long line.

No. The tool takes one .svg file at a time and has no box for pasting code. Dropping two files shows the same error as a wrong file type. Compressed .svgz files are not accepted, so unpack them to a plain .svg first. To clean many files in one go, use the Batch SVG Optimizer.

It runs SVGO 4 in your browser, with a fixed set of 13 plugins instead of the default preset. Six of them are the switches in the editor. The other seven always run and remove editor data, the XML header, the doctype and empty tags.

No. Your SVG is read and optimized inside this browser tab, and the result is saved straight to your downloads. The page sends anonymous usage stats, such as which switches were on and a rough file size, but never the SVG code or its name.
