SVG Editor

This tool is an online SVG editor designed for developers, designers, and content creators who produce scalable vector graphics for web and apps. It accepts raw SVG code and transforms it through a DOM‑like editing model that preserves semantics while applying formatting and optimization rules. The core value is end‑to‑end lifecycle support: validate syntax, normalize attributes, adjust coordinate systems, and prepare assets that are ready for deployment in production pipelines. By focusing on standards compliance and deterministic outputs, it reduces drift between design intent and rendered results.
Core Logic & Features: The tool parses SVG input into an internal DOM‑like model, validates XML well-formedness, and applies transformation rules. Required features include: input SVG parsing, syntax validation, and an output generator that preserves structure while applying edits. Optional/advanced features include: viewBox normalization, unit conversion (px to viewBox units), automatic id deduplication, attribute normalization, minification, formatting, and error reporting. It supports transformations such as set width/height, adjust preserveAspectRatio, and reformatting of elements.
Inputs & Outputs: Inputs include: svg_code (string, required), width (number, optional), height (number, optional), minify (boolean, optional), prettify (boolean, optional), preserve_ids (boolean, optional). Outputs: formatted_svg (string), diagnostics (array of messages, optional), stats (object: length, characters, elements).
Algorithms & Calculations: XML parsing validates syntax; DOM-based edits apply changes; minification removes whitespace; path data optimization uses basic simplification; no external references. Error handling uses numeric error codes and precise position hints; fallback to original if unrecoverable.
Error & Edge Cases: Malformed SVG triggers diagnostic with line/column; missing svg root yields a minimal wrapper; external entity references are blocked; extremely large SVGs are rejected above size thresholds.
Industry/Region & Localization: Output follows W3C SVG 1.1/2.0 conventions; units in user-specified or px; supports UTF-8 identifiers; no regional compression by default.
Assumptions & Exclusions: Excludes raster conversion, bitmap editing, animation timeline editing, and color profile embedding. Not responsible for UI concerns; no server-side rendering beyond transformation.
