SVG Viewer & Optimizer

Preview SVG code, read its dimensions, optimize and minify it with SVGO, then copy or download — privately in your browser.

How it works

  1. 1

    Paste SVG

    Drop SVG markup into the editor, or upload an .svg file.

  2. 2

    Preview & inspect

    See the rendered image plus its width, height and file size.

  3. 3

    Optimize

    Run SVGO to shrink the file, then copy or download the cleaned-up SVG.

Instant & 100% private — nothing is uploaded

Everything runs locally in your browser. Your code, text and files are processed on your own device and are never sent to a server — so there are no upload waits, no size limits from us, and nothing is ever stored or logged.

Frequently asked questions

How much smaller will SVGO make my file?
It varies, but editor-exported SVGs often shrink 40–70% by removing metadata, comments and redundant precision, with no visual change.
Is the preview safe?
The SVG is sanitized before rendering, so embedded scripts are removed. You still see an accurate visual preview of the artwork.
Can I download the optimized SVG?
Yes. Copy the optimized markup or download it as a file, ready to drop into your project.
Is my data sent to a server?
No. Everything runs locally in your browser using JavaScript and WebAssembly. Your input never leaves your device, nothing is uploaded, and nothing is logged or stored.
