SVG Viewer and Editor — Preview, Edit & Optimize SVG Online
Paste raw SVG code and see it rendered instantly with this free online SVG viewer and editor. Inspect icons and illustrations on a checkered transparency grid, zoom into details, edit the XML live, and format messy markup into clean, readable code — all in your browser.
It is the fastest way to answer everyday SVG questions: What does this icon in my codebase actually look like? Why is this path invisible? What changes if I tweak this fill? Edit the source on one side and watch the preview update in real time on the other.

Frequently Asked Questions
How can I preview an SVG file without installing software?
Open the .svg file in a text editor, copy its contents, and paste the code here — it renders instantly with zoom and a transparency grid. No installs or uploads needed.
Why is my SVG rendering blank?
Common causes: a missing or zero-sized viewBox, fill="none" on every path, width/height of 0, or a fill that matches the background. Paste the code here and toggle attributes live to find the culprit.
Can I edit SVG code directly in this tool?
Yes — the editor is fully live. Modify paths, colors, transforms, or the viewBox and watch the rendered output change in real time.
Does this work with SVGs exported from Figma or Illustrator?
Yes. Paste any exported markup; the built-in formatter also cleans up the dense single-line output those tools produce so it becomes human-readable.
