What is inside it

Quick Tool Overview

The SVG Viewer puts markup and render side by side, updating as you type, and reports what is actually in the file: viewBox, element count, every colour used, external font and image references, and whether it has an intrinsic size. That last group is what makes an SVG render blank elsewhere.

About the SVG Viewer

SVG is text, which is its great advantage and the reason it is awkward to work with: you cannot tell what a block of markup draws without rendering it.

This is markup on one side and the render on the other, updating as you type. Alongside the preview it reports what is actually in the file — the viewBox, the element count, every colour used, whether it references external fonts or images, and whether it has an intrinsic size. That last group is what causes most of the confusion when an SVG renders blank in a canvas or an email, so it is called out rather than left to be discovered.

Key features of the SVG Viewer

Live render

The preview follows every keystroke, which is the fastest way to adjust a fill or a path.

Flags the blank-render causes

Missing viewBox, zero dimensions and external references are called out rather than discovered later.

Colour inventory

Every fill and stroke colour listed, which is how you find the one hard-coded value in an icon set.

Element count

A quick read on complexity, and on whether a file needs optimising before shipping.

Export to PNG

Rasterise the current markup at any size without leaving the page.
