What is an SVG Viewer?
An SVG viewer renders vector markup so you can confirm shapes, paths, gradients, symbols, groups, and sizing before using the file in a web page or design system.
SVG Viewer / Formatter
Paste SVG markup to safely preview, format, inspect, copy, and download SVG files locally in your browser.
SVG input
Paste SVG markup, exported icons, symbols, gradients, paths, and groups.
SVG is treated as untrusted markup. Preview runs in a sandboxed frame after scripts, event handlers, embedded content, and external references are blocked.
SVG preview and output
Safe preview, validation status, SVG summary, warnings, and formatted markup.
Ready to view SVG
Paste SVG or load a sample, then format and preview it in a locked sandbox.
Press Ctrl+Enter or Command+Enter in the editor to format immediately.SVG Viewing Guide
View, format, and inspect SVG without uploading files
Use the SVG Viewer / Formatter to validate vector markup, preview sanitized artwork, inspect the root dimensions and viewBox, and prepare readable SVG source for review.
What SVG formatting changes
Formatting adds readable indentation and line breaks after XML validation. It preserves namespaces, attributes, comments, defs, symbols, gradients, paths, and groups.
Safe SVG previewing
SVG can include active markup. This tool previews a sanitized copy inside a sandboxed frame and blocks scripts, handlers, embedded content, and external references.
Inspecting viewBox
The viewBox defines the coordinate system used for responsive scaling. Missing viewBox warnings help catch icons and illustrations that may not resize cleanly.
SVG Viewer vs SVG Optimizer
Use the viewer to read, format, inspect, and preview SVG. Use SVG Optimizer when the goal is minifying markup and reducing file size for production assets.
Common SVG issues
Invalid XML, missing viewBox values, external references, inline event handlers, scripts, huge path-heavy files, and embedded content are common review points.
SVG Viewer FAQ
Does this SVG viewer upload my file?
No. Formatting, validation, preview preparation, copy, and download actions run locally in your browser.
Will scripts or event handlers run?
No. The preview uses a sandboxed frame and a sanitized SVG copy with scripts, inline handlers, embedded content, and external references removed.
Does formatting optimize or minify SVG?
No. Formatting makes SVG easier to read. Use SVG Optimizer when you want cleanup options and smaller output.
Why does missing viewBox matter?
Without a viewBox, CSS-sized SVGs can scale unexpectedly because the browser has less information about the internal coordinate system.
Can I download the formatted SVG?
Yes. After valid SVG markup is formatted, download writes the formatted source as a local .svg file.
Can this inspect gradients, defs, symbols, paths, and groups?
Yes. The formatter preserves those structures and the summary counts elements and paths while reporting root width, height, and viewBox.
