Preview tool for path debugging—not a full vector illustration editor. Verify exported paths in target browsers before production release.
Skip to SVG path editorLoading tool…
Free SVG path editor — paste d commands or upload SVG, preview with pan/zoom, inspect commands, beautify or minify path data, and copy or download updated SVG. Runs locally in your browser; no upload or signup.
The editor detects whether input is raw path data or full SVG markup, validates d strings using the browser SVG DOM (getTotalLength / getBBox), sanitizes full SVG documents, and renders paths inside a pannable viewBox camera.
Enter a d attribute, raw path commands (e.g. M 10 10 L 90 90), or upload an .svg file. Try an example chip for a quick start.
Drag to pan, use zoom buttons or Ctrl/Cmd +/−/0, toggle the alignment grid for path-only input, and review path length and bounds.
Expand the command reference to see what each M/L/C/Q/A/Z segment does. The highlighted d panel color-codes commands vs numbers.
Copy the d string only, copy full SVG markup, beautify or minify whitespace, or download a .svg file.

Common real-world scenarios where this tool saves time.
Frontend developers
Paste d strings from Heroicons or Lucide exports, tweak coordinates, and copy updated markup into components.
Designers learning SVG
Load example paths (line, cubic, quadratic, triangle) and read command explanations alongside the preview.
Illustration handoff
Confirm path geometry in this editor, then move to SVG Color Editor for fill and stroke palette changes.
Step-by-step chains that connect related tools for common tasks.
Continue the workflow with the right follow-up tool.
Uppercase commands use absolute coordinates; lowercase uses offsets from the current point.
| Command | Mode | Typical use |
|---|---|---|
| M / m | Move to | Start each subpath—uppercase anchors, lowercase offsets |
| L / l | Line to | Straight segments in icons and diagrams |
| C / c | Cubic Bézier | Smooth curves with two control points |
| Q / q | Quadratic | Simpler curves with one control point |
| Z / z | Close path | Connect back to subpath start for filled shapes |
| Tool | Strength | Limitation |
|---|---|---|
| This path editor | Fast d-string debug, local preview, copy/export | No draggable Bézier handles |
| Figma / Illustrator | Visual curve editing, layers, effects | Requires desktop app or account |
| Browser DevTools | Inspect rendered DOM SVG | No dedicated path metrics or command walkthrough |
Use SVG Path Editor to debug and edit d strings. Use SVG Viewer to inspect files, SVG Color Editor for palette changes, and SVG to PNG when you need raster output.
| Related tool | Use this tool when | Use related tool when |
|---|---|---|
| SVG Viewer | You need to edit, validate, or export path d data with live preview and command explanations. | You only need to browse, zoom, or inspect an SVG file without editing path strings. |
| SVG Color Editor | Path geometry is final and you need to change fill or stroke hex values across the file. | Colors are correct but d coordinates or curve commands need debugging. |
| SVG to PNG | You are still editing vector path markup in SVG format. | Path and colors are done and you need a PNG raster for email, slides, or OG images. |
SVG paths without moveto may render unpredictably. Always begin subpaths with M/m before lines or curves.
Lowercase l/c/q segments make icon sets easier to translate—absolute M still anchors the subpath origin.
Readable d strings help code review; minified paths reduce HTML payload when inlined in pages.
Ensure the path starts with M or m (moveto). Check coordinates are inside the viewBox—or click Fit to view.
Arc segments need seven numbers: rx, ry, rotation, large-arc flag, sweep flag, x, y. Missing flags are a common typo.
Some exports use <polygon> or <rect> instead of <path>. Convert shapes to paths in your design tool first.
Likely cause: Unclosed tags, unescaped characters, or XML entities in pasted markup.
Fix: Paste through an XML validator or re-export from your design tool as plain SVG.
Likely cause: Path not yet painted or d string failed silent render.
Fix: Wait for debounced parse (~200ms) or check the path warning banner for validation hints.
Likely cause: External CSS or defs referenced outside pasted markup.
Fix: Inline styles in the SVG or open the complete file in SVG Viewer.
This is a text-based path debugger, not a canvas editor. Use Figma or Illustrator for interactive control-point editing.
Use SVG Color Editor to swap palette colors across an entire SVG after path geometry is final.
Use SVG Viewer to browse dimensions, metadata, and multi-element documents without focusing on d strings.
Yes—paste complete SVG markup or upload an .svg file. All path elements are detected; the first path is highlighted and explained in the command reference.
Standard SVG path commands: M/m, L/l, H/h, V/v, C/c, S/s, Q/q, T/t, A/a, and Z/z. The preview uses the browser's native SVG renderer.
Yes—copy d only, copy full SVG markup, or download a .svg file. For path-only input, a minimal SVG wrapper is generated automatically.
No—it is a lightweight browser debugger for path strings, not a full vector design suite with Bézier handles.
Check for typos in commands, a missing M at the start, coordinates outside the viewBox, or invalid arc flags. Use Fit to view after parsing.
No. Parsing, validation, and preview run entirely in your browser. Pasted and uploaded SVG never leaves your device.
Yes. Use Undo/Redo buttons or Ctrl+Z / Ctrl+Y in the editor. Example chips and file uploads are tracked in history too.
Beautify adds readable spacing after commands. Minify removes extra whitespace to shrink the d string for production embeds.
All parsing, validation, and preview run in your browser. SVG files are never uploaded, stored, or transmitted to EverydayTools servers.
Rendering uses the browser SVG engine. Path length and bounding boxes match what the same d string would produce when embedded in HTML.
DOMParser → d validation → sanitized preview → SVGPathElement metrics. Your Network tab stays empty during editing.
