Simplify and optimize SVG path data by reducing decimal precision, removing redundant points, and cleaning path commands for smaller, cleaner SVG files.

Drag the slider to choose decimal places (0–6). Lower = smaller file, higher = more accurate paths.

SVG files exported from tools like Figma, Adobe Illustrator, or Inkscape often contain excessive decimal precision — coordinates like M10.123456 20.654321 when M10.12 20.65 is visually identical. This tool strips that unnecessary precision, removes XML comments, and collapses redundant commands to produce a leaner file.
For most web icons and UI elements, 1–2 decimal places is sufficient and produces the best size reduction. For complex illustrations or technical diagrams where accuracy matters, use 3–4. Precision of 0 is lossy but creates the smallest files.
At precision ≥1, the visual difference is virtually imperceptible for standard web use. At precision 0 (integer only), there may be slight rounding at sharp curves on very small icons. Always preview before using in production.
This tool focuses on numeric precision and XML comments. It does not strip metadata like <title>, <desc>, or id attributes. For full metadata removal, use the SVG Optimizer tool.
SVG Optimizer performs a broad cleanup — removing empty groups, unused defs, and metadata. This tool focuses specifically on numeric path precision, giving you fine-grained control over how many decimal places are kept in path coordinates.
Yes! You can paste a raw path data string like M10.456 20.789 L50.123 80.456 Z directly. The tool will round the numbers according to your chosen precision.
All processing happens server-side via a secure API call and in the browser — your SVG data is never stored or logged. Files are processed in memory and discarded immediately after the response.
An SVG Path Simplifier is a tool that reduces the numerical verbosity of SVG path data without meaningfully changing the visual output. When design applications export SVG files, they record path coordinates with high floating-point precision — often 6 or more decimal places. A coordinate like M47.384716 23.019283 is mathematically precise but visually indistinguishable from M47.38 23.02 on any screen at any zoom level.
By rounding coordinates to a lower precision, we eliminate wasted bytes. A large icon sheet or illustration can shrink by 10–40% through precision reduction alone — without touching the visual quality that end users see.

The answer lies in how vector drawing tools work internally. Applications like Adobe Illustrator, Figma, Sketch, and Inkscape use floating-point arithmetic to represent every anchor point, control handle, and curve. When you draw a simple rounded rectangle or import a logo, the application records the exact mathematical coordinates of every point.
For internal use, this high precision is valuable — it allows non-destructive editing, scaling, and mathematical operations without accumulated rounding errors. But when you export for the web, that precision is overkill. A browser renders SVG at screen resolution, where sub-pixel differences are invisible. A coordinate difference of 0.000001 pixels is meaningless.
Consider a complex SVG icon with 500 path points. If each coordinate averages 8 characters at 6 decimal places (47.384716) and we reduce to 1 decimal place (47.4), we save roughly 4–5 characters per coordinate. With 500 × 2 coordinates (X and Y), that's up to 5,000 characters — approximately 5KB — on a single icon. Multiply that across an icon sprite or illustration library and the savings become significant.
The table below shows typical savings by precision level for a medium-complexity SVG illustration:
SVG paths are defined using a mini-language of single-letter commands. Understanding them helps you reason about what gets simplified:
M / m — Move to (absolute / relative). Sets the starting point.L / l — Line to. Draws a straight line to a point.H / h — Horizontal line. Takes a single X coordinate.V / v — Vertical line. Takes a single Y coordinate.C / c — Cubic Bézier curve. Takes three coordinate pairs.Q / q — Quadratic Bézier. Takes two coordinate pairs.A / a — Elliptical arc. Takes radius, rotation, flags, and endpoint.Z / z — Close path. Returns to the starting point.Precision reduction applies to all numeric arguments of these commands. The structural meaning of the path — which commands appear, in which order — is preserved. Only the floating-point values are rounded.
Precision reduction is one tool in a broader SVG optimization workflow. For maximum file size savings, combine it with:
<title>, <desc>, editor namespaces (xmlns:inkscape, etc.) if not needed.<!-- ... -->) add no visual value and can be large in auto-generated files.<g> elements with no transform or style add structure without benefit.There are cases where keeping high precision matters. If your SVG is used as a source file for further editing (not just web delivery), reduce precision only on exported copies, not the original. Similarly, scientific or engineering diagrams where coordinates represent real measurements should maintain accuracy. Finally, if your SVG contains very small elements (under 4px rendered size), precision 0 may cause noticeable jaggedness on curves.
Optimized SVGs are a foundation of high-performance web design. They scale infinitely without quality loss, support CSS styling and animation, and weigh a fraction of equivalent raster images. Here are best practices for SVG in production:

It handles complete SVG documents as well as raw path data strings, applies configurable decimal precision, removes XML comments, and provides a live preview so you can confirm the visual result matches your expectations. No account, no upload limits, no watermarks — just clean SVG output ready for production.
