SVG viewer & inspector
Your file manager still can't preview an SVG, but your browser has rendered them natively for twenty years. Open any SVG here: preview it on checker, light, or dark backgrounds, zoom into the details, and see what's actually inside — dimensions, viewBox, element counts, full source. Nothing uploads, and embedded scripts never run.
Inspecting like you mean it
- 01
Flip the background
A white logo on the default white preview looks like an empty file. The checker/light/dark switcher exists precisely for that thirty-second heart attack.
- 02
Trust the viewBox, not width/height
Missing width/height attributes don't make a file broken — the viewBox is what defines scalable geometry. If both are missing, that's the real problem.
- 03
Element counts tell you the file's story
A simple icon with 400 paths is an unoptimized trace or a rogue export. High counts explain big files — and the Optimizer is one click away in the links below.
Questions, answered
Why won't my computer preview SVG files?+
Most OS file managers still ship without SVG thumbnailing — Windows Explorer shows a generic icon and macOS Quick Look support is patchy. Browsers render SVG natively, which is why a browser-based viewer needs no install and no upload.
Is it safe to open an SVG from someone I don't know?+
Here, yes. SVGs can technically contain scripts, but this viewer renders through an <img> element, where browsers never execute scripts or load external resources. Be more careful pasting unknown SVG markup directly into a webpage's HTML — that's the risky context, not this one.
What's the difference between width/height and the viewBox?+
width/height suggest a default display size; the viewBox defines the drawing's internal coordinate system — it's what lets an SVG scale to any size. A file with a viewBox and no width/height is perfectly healthy and simply sizes to its container.
Why does my SVG render blank or partially?+
The usual suspects: the artwork references external images or fonts (not loaded in the <img> sandbox), everything sits outside the viewBox, or fills are white — flip the preview background to dark to check that last one instantly.
Can I edit the SVG here?+
This page is for viewing and inspecting. To shrink the file, use the SVG Optimizer; to turn raster images into SVG, the converter on the home page; for real editing, the file opens in Figma, Inkscape, or Illustrator — the code panel here lets you copy it straight over.
