How SVG optimization works
Your file is processed with SVGO, the widely used open-source SVG optimizer, using its default preset in multipass mode: the passes repeat until the file stops getting smaller. This is what changes.
Editor and document overhead is stripped
The XML declaration, DOCTYPE, comments and <metadata> blocks are removed, along with the extra namespaces and attributes that editors such as Inkscape, Illustrator and Sketch write into the file. Generic "Created with…" descriptions go too. None of this affects how the image is drawn.
Numbers are rounded and path data is rewritten
Coordinates and other numeric values are rounded to three decimal places. Path commands are rewritten into their shortest equivalent form, redundant segments are dropped, and neighbouring paths with identical styling can be merged into one.
Shapes, groups and transforms are simplified
Rectangles, lines and polygons are converted to paths when that is shorter. Empty groups and containers are removed, wrapper groups that add nothing are collapsed, and transforms are combined or applied where possible.
Styles and colors are cleaned up
Colors are written in their shortest form (for example #ff0000 becomes red), CSS inside <style> is minified, attributes that only repeat SVG defaults are removed, and hidden or empty elements are deleted.
Unused IDs and definitions are removed
IDs that nothing inside the file refers to are deleted, and unused gradients, patterns and other <defs> are dropped. IDs that are still referenced keep their original names; they are not shortened.
The viewBox is kept, fixed dimensions are not
The viewBox is always preserved so the graphic scales correctly. The width and height attributes are removed, so the SVG fills whatever box you place it in. The result is written on a single line with attributes in a consistent order, which also helps gzip.
What is safe to optimize, and when to be careful
Static icons, logos and illustrations exported from design tools, including SVGs made with our converters, are safe to optimize and usually benefit the most. Check the result more closely in these cases.
IDs used by outside CSS, JavaScript or sprites
The optimizer only sees the file itself. If an external stylesheet, a script or a <use href="icons.svg#name"> on another page targets an ID, that ID looks unused and will be removed. Files that contain their own <style> or <script> element keep their IDs.
Animated SVGs
SMIL or CSS animations that morph path data, or that rely on a specific group structure, can break when paths are rewritten and groups are collapsed. Simple animations usually survive, but always preview the result before replacing the original.
Accessibility text
The <title> element is removed. If a screen reader needs a label, add alt text on the <img> tag or an aria-label where you embed the SVG.
Layers you show and hide with code
Elements hidden with display="none" or zero opacity are treated as invisible and removed. If your script reveals them later, optimize a copy without those layers hidden.
Files you still want to edit
Inkscape layers, guides and other editor data are gone after optimization. Keep your source file for editing and publish the optimized copy.
SVG optimizer FAQ
Will optimizing change how my SVG looks?
For almost all files, no. The changes remove data that is not rendered and rewrite the rest in shorter form. The only visible effect can come from rounding to three decimal places, which may show on graphics with a very small viewBox viewed at large sizes.
How much smaller will my SVG file get?
It depends on where the file came from. Exports from design tools with metadata, comments and long decimal numbers often shrink a lot, while files that were already minified shrink very little. The result page shows the exact size before and after.
What is the maximum file size?
You can upload SVG files up to 10 MB. You can also paste SVG code directly into the Paste Code tab instead of uploading a file.
Why were the width and height attributes removed?
The optimizer keeps the viewBox and drops fixed width and height so the SVG scales to its container. If you need a fixed size, set width and height on the <img> tag or in CSS.
Is it safe to optimize SVGs used in a sprite or by JavaScript?
Be careful. IDs that are only referenced from outside the file are removed because the optimizer cannot see those references. Test the optimized file in place, or keep the original for those cases.
Does the optimizer remove accessibility information?
It removes the <title> element and generic editor descriptions. Provide the accessible name where the SVG is embedded, for example with alt text or an aria-label.
