SVG Code Cleaner & Viewer

How This Tool Works

Operation: The SVG Cleaner & Optimiser parses SVG markup and applies a series of text-based optimisation passes to reduce file size while preserving visual fidelity. The optimisation passes include:

• Whitespace removal: Removes unnecessary spaces, tabs, and line breaks between tags and attributes.
• Decimal precision reduction: Truncates numeric coordinate values to configurable decimal places (default 2). A path coordinate like 123.456789 becomes 123.46 — visually identical but smaller.
• Attribute removal: Strips SVG attributes with default values (e.g., fill="black" when default is black, stroke-width="1").
• Style inline consolidation: Moves inline style declarations to presentation attributes where possible, standardising the format for cleaner output.
• Empty element removal: Removes , , and other grouping elements that contain no children or meaningful attributes.
• Comment stripping: Removes XML comments, editor metadata, and boilerplate generator tags.

Key Benefits of Using the SVG Cleaner

• Entirely local optimisation: Your SVG files — potentially containing proprietary icons, logo designs, or UI assets — are processed entirely in your browser. No file data is uploaded to any server, protecting your design assets from IP theft.
• Configurable precision: Choose how aggressively to round decimal coordinates (0–6 decimal places). A precision of 0 yields maximum compression but may shift fine details; precision of 2–3 is visually lossless for most designs while significantly reducing file size.
• Real-time preview and comparison: View the original SVG rendered beside the optimised version to visually verify that no artefacts, shifted paths, or colour changes were introduced during optimisation.

Practical Real-World Use Cases

• Frontend developers optimising SVG icon systems: A developer with a set of 200 SVG icons for a design system can paste each icon through the cleaner, reducing file sizes by 30–50% without any visual change — directly improving page load performance on icon-heavy sites.
• Graphic designers preparing web graphics: A designer who exported SVGs from Adobe Illustrator with verbose metadata, groups, and decimal-heavy coordinates can clean and minify the output before delivering to the development team.
• E-commerce sellers uploading product diagrams: A seller adding SVG-format product dimension diagrams to product listings can optimise each file to under 5KB, ensuring fast image loading on mobile connections.
