SVG path normalization is the process of converting all relative path commands (lowercase letters like m, l, c) into their absolute equivalents (uppercase M, L, C). This makes the path data consistent and easier to manipulate programmatically, as every coordinate is expressed in absolute terms relative to the SVG coordinate system origin.

Absolute paths are easier to parse, analyze, and transform with scripts. They eliminate the need to track the "current point" when computing bounding boxes, applying matrix transformations, or performing path boolean operations. Many SVG processing libraries and CNC machines also require absolute coordinates. Additionally, absolute paths can be slightly easier to debug since each coordinate is self-contained.

This tool supports all standard SVG 1.1 path commands: M/m (moveto), L/l (lineto), H/h (horizontal lineto), V/v (vertical lineto), C/c (cubic bezier), S/s (smooth cubic bezier), Q/q (quadratic bezier), T/t (smooth quadratic bezier), A/a (elliptical arc), and Z/z (closepath). Mixed paths containing both relative and absolute commands are fully supported.

The conversion is mathematically exact. You can adjust the output decimal precision from 0 to 10 places using the precision control. The default of 4 decimal places provides sub-pixel accuracy suitable for most web and design work. The tool preserves the original geometric intent of your path, including proper handling of reflected control points in smooth bezier curves (S/s and T/t commands).

In SVG path syntax, uppercase letters (M, L, C, etc.) represent absolute coordinates — each point is specified directly in the SVG coordinate space. Lowercase letters (m, l, c, etc.) represent relative coordinates — each point is offset from the previous point's position (the "current point"). This relative system allows you to create reusable path fragments that can be placed anywhere simply by changing the starting moveto command.

Yes! You can paste multiple path definitions (separated by whitespace or newlines) and the tool will process them sequentially. Each d attribute value is normalized independently. If you have multiple SVG elements, simply paste each path's d value one at a time. For batch processing of many files, consider using a command-line SVG optimization tool.

Absolutely. All processing happens entirely in your browser using client-side JavaScript. Your path data never leaves your device — nothing is uploaded to any server. You can verify this by disconnecting your internet after the page loads; the tool will continue to work perfectly. This makes it safe for proprietary or confidential SVG assets.
