SVG Optimizer & Minifier

An SVG exported straight from a design tool almost always carries extra weight it does not need once it ships to production: editor metadata describing layers and tool version history, XML comments left behind by the export process, empty grouping elements from a design file's layer structure, and path coordinates specified to far more decimal precision than any screen can actually render. This tool strips all of that automatically, shrinking file size measurably without changing how the artwork looks, and shows you exactly how much smaller the result is before you use it.

Where all that extra weight actually comes from

Design tools like Figma, Illustrator, and Inkscape export SVG in a format optimized for round-tripping back into the design tool itself, not for shipping to a browser. That means the export often includes editor-specific XML namespaces, Inkscape's inkscape: and sodipodi: attributes are a common example, metadata blocks describing authorship or tool version, comments marking layer boundaries, and empty wrapper elements left over from a layer structure that has no visual meaning once flattened into a browser. None of this affects how the SVG renders, it exists purely to help the originating design tool reconstruct its own internal editing state, which is completely irrelevant once the file is sitting in a website's asset folder.

Why excessive decimal precision matters more than it seems

Path data exported from a design tool frequently specifies coordinates to six or more decimal places, a value like 18.000001 instead of simply 18, or 30.111111 instead of 30.11. At typical icon and illustration sizes, no screen, browser, or human eye can distinguish a coordinate specified to six decimal places from one rounded to two, the visual difference is smaller than a single device pixel. But every one of those extra digits is still raw text taking up bytes in the file, and across a path with dozens of coordinate pairs, that adds up to real, measurable file size with zero visual benefit. Rounding to two decimal places, the default here, removes this waste while staying well within any precision a browser could actually render differently.

Choosing exactly which optimizations to apply

Not every project needs every optimization, so each cleanup step here is an individually toggleable checkbox rather than a single all-or-nothing button. Strip comments removes XML comments entirely. Strip editor metadata removes namespaced attributes and elements specific to known design tools, along with any now-unused xmlns declarations for those namespaces. Remove empty groups repeatedly checks for and removes elements with no children and no meaningful attributes, since removing one empty group can sometimes expose a newly empty parent group above it. Collapse whitespace removes unnecessary spacing between tags. Round decimals rounds path and coordinate precision to 2 decimal places. Turning off a specific optimization is useful when, for example, a decorative comment intentionally documents licensing information you want preserved.

What this is not: full structural minification

Being clear about scope: a fully featured optimizer like the industry standard SVGO can also merge redundant paths, convert shapes to their more compact path equivalents, and apply more aggressive structural transformations that carry some, usually small, risk of subtly altering rendering in edge cases. This tool intentionally sticks to safe, purely non-visual cleanup, metadata, comments, empty elements, whitespace, and precision, that carries effectively zero risk of changing how the artwork looks, prioritizing predictability over squeezing out every possible byte. For most icon and logo use cases exported from a standard design tool, this covers the overwhelming majority of the actual bloat.

Runs entirely in your browser

Every optimization step runs client side using your browser's own XML parsing and string processing, nothing you paste or upload is sent to a server. Once your SVG is optimized, our SVG Code Editor is a natural next step for any further manual adjustments, and our SVG Viewer & Validator is worth running afterward to confirm the optimized result still passes structural validation, both part of the same SVG & Design Tools collection this tool belongs to.
