SVG Font to Path Explainer & Linter
SVG Font to Path Explainer & Linter: Scans XML DOM for `<text>`, `<tspan>`, and `@font-face` declarations that could cause cross-platform font fallback issues.
About this svg font to path explainer & linter
SVG Font to Path Explainer & Linter — browser-based utility.
How this tool works
Performs three textual checks: an `<svg` marker must exist, `<font-face` is reported as legacy, and `<script` is rejected. It does not parse XML, inspect text or tspan elements, verify path conversion, or sanitize SVG.
- XML DOM & Path Parsing: Parses SVG text into an XML DOM tree, extracting viewBox, path elements, and styling attributes.
- Vector Coordinate Optimization: Truncates excessive floating-point decimals in path coordinates (e.g. from 8 decimals to 2 decimals).
- Metadata & Node Pruning: Removes unnecessary XML headers, DOCTYPE declarations, editor metadata, and collapsed empty container tags.
- Rasterization & Data URI Encoding: Renders vector curves to high-DPI canvas buffers or encodes clean SVGs to base64 Data URIs.
Worked example
Scenario: Report two heuristic SVG font safety findings.
Sample input:
Processing: Run the font-face and script regex checks after confirming the SVG root.
Illustrative output:
Limits and verification
Ensures coordinate rounding precision does not deform complex curves or tiny vector icons (minimum 1-2 decimal places recommended). Sanitizes embedded script tags (<script>) to prevent Cross-Site Scripting (XSS) in untrusted SVG inputs.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
What does the SVG font linter check?+
It uses three regex heuristics: an SVG root must exist, font-face is flagged as legacy, and script is flagged as disallowed. It returns joined messages or one pass sentence.
Which inputs and controls are exposed?+
Only SVG text and local Run exist. There is no file upload, DOM parser, font extraction, outline conversion, SVG rendering, font embedding repair, export, or batch mode.
What limits apply to the linter?+
The checks are substring heuristics, not SVG conformance or font licensing analysis. It does not inspect text elements, glyph paths, external references, computed fonts, or all security hazards.
What did the browser fixture verify?+
For an SVG containing font-face and script, it independently confirmed both legacy-font and disallowed-script messages.
