What is the svg viewer?

GigAI SVG Viewer renders SVG files safely in your browser with zoom, pan, background toggles and source inspection - no upload, which matters because SVGs can contain scripts and you shouldn't paste unknown ones into production. Pair with the SVG Optimizer before shipping.

The GigAI SVG Viewer is a desktop-grade way to open and inspect SVG files without launching a heavyweight editor. Drag a.svg onto the canvas, paste markup from your clipboard, or load a built-in sample, and it renders instantly on a checkerboard backdrop that reveals true transparency, with one-click light and dark backgrounds so you can judge how the graphic looks against real surfaces. Fit-to-screen and 50/100/200% zoom let you scrutinise hairline strokes and alignment, while a live dimensions readout shows the intrinsic width, height and viewBox. Below the canvas, a composition panel built on our analyzer counts every element by tag (paths, rects, circles, groups, gradients, filters), lists the distinct colors referenced in fills, strokes and gradient stops, flags whether the file carries animation, gradients or filter effects, surfaces the viewBox, and reports the exact byte size. A synced source-code pane lets you read and lightly edit the markup and watch the preview update live. Because everything runs locally in your browser using the native DOMParser (no server, no upload, no account) you can safely open logos, icons and design exports that contain brand assets or client work. It is the fastest path from 'what is inside this SVG?' to a clear, trustworthy answer, and it links straight to our optimizer and React/Data-URI converters when you are ready to ship the file.

How to use the svg viewer

  1. 1

    Open your SVG

    Drop an .svg file onto the canvas, paste markup into the source pane, click to browse, or load a built-in sample to try it instantly.

  2. 2

    Preview & zoom

    Toggle the checkerboard, light or dark background and use Fit or 50/100/200% zoom to inspect the graphic. The dimensions readout updates live.

  3. 3

    Read the report

    Scan the composition panel for element counts, colors, viewBox, feature flags and byte size to understand exactly what the file contains.

  4. 4

    Copy, download or optimize

    Copy the source, download the.svg, or jump to the SVG Optimizer to shrink it, then to the React or Data-URI converter when you are ready to ship.

What SVG Viewer includes

  • Transparency-true canvas

    A checkerboard backdrop reveals real transparency, and one-click light and dark backgrounds show exactly how the graphic reads against white, dark UI or a printed page.

  • Zoom & live dimensions

    Fit-to-screen plus 50/100/200% zoom to inspect hairline strokes and alignment, with a live readout of the SVG's intrinsic width, height and viewBox.

  • Full composition report

    See every element counted by tag (paths, rects, circles, groups, gradients, filters) the total node count, and the exact byte size, so you know precisely what is inside.

  • Colors & feature flags

    Extracts the distinct colors used in fills, strokes and gradient stops, and flags whether the file carries animation, gradients or filter effects at a glance.

  • Source-code pane

    Read the raw markup beside the preview, lightly edit it, and watch the canvas redraw live: perfect for spotting a stray transform, missing viewBox or oversized path.

  • 100% in your browser

    Rendering and analysis use the browser's native DOMParser on your device. No SVG is ever uploaded, stored or logged. Open confidential brand and client files safely.

Why use our svg viewer

Understand any SVG in seconds

Instead of squinting at raw XML, get a rendered preview plus a plain report of elements, colors and features, the fastest way to answer 'what is this file?'

Catch problems before you ship

A missing viewBox that breaks scaling, an accidental filter that bloats the file, or a hidden animation all surface immediately, so bad SVGs never reach production.

Judge it against real backgrounds

The checkerboard reveals transparency and the light/dark toggle shows the graphic on the surfaces it will actually live on, so contrast and halos are obvious.

Private by design

Because it runs locally, you can open logos, unreleased icon sets and client exports with zero risk of anything leaving your machine.

Built for the way you work

From quick one-off fixes to daily workflows, see how people put this tool to use.

  • Frontend developer

    Inspect an icon before importing

    Open an icon exported from Figma to confirm it has a viewBox, no stray width/height, and no rogue filters before you inline it or convert it to a component.

  • Designer

    Check transparency and edges

    View a logo on the checkerboard to spot unwanted background fills or anti-alias halos, then flip to a dark canvas to verify it works in a dark UI.

  • Design-systems engineer

    Audit an icon set

    Paste each icon to compare element counts, colors and byte sizes, catching outliers that are far heavier or use hard-coded colors that should be currentColor.

  • Support / QA

    Open a file a client sent

    Quickly render an SVG someone emailed to confirm it displays correctly and read its dimensions, without trusting an unknown desktop app or uploading it anywhere.

Supported formats

Accepts SVG and TXT, and produces SVG, all processed locally in your browser.

Common problems, solved

Hit a snag? Here are quick fixes for the issues people run into most.

  • My SVG renders blank or clipped.

    Check the composition panel for a viewBox. If it is missing, the graphic has no defined coordinate space and may render at 0×0 or clip. Add a viewBox matching your artwork bounds, or open it in the SVG Optimizer which can preserve/add one.

  • It looks different here than in my design tool.

    Browsers render standard SVG. Some editors add proprietary namespaces, embedded fonts or effects that browsers ignore. Flatten text to paths and remove editor-specific metadata (the Optimizer does this) for consistent cross-browser rendering.

  • The colors panel is empty but the image has color.

    Colors defined only in a <style> block, via CSS classes, or through url(#gradient) references may not appear in the fill/stroke color list. The gradients flag will still light up. Open the source pane to read the <style> or <defs> directly.

  • Animation isn't playing.

    SMIL (<animate>) and CSS keyframes render in the live preview, but the report will flag animation so you know it is present. If it appears static, the animation may be JavaScript-driven, which the sandboxed preview strips for safety.

Get the most out of it

  • Flip to the dark background to catch light-colored strokes or halos that vanish on white.

  • Watch the element count, an icon with hundreds of nodes is a prime candidate for the SVG Optimizer.

  • No viewBox in the report is the #1 cause of SVGs that won't scale responsively. Add one before shipping.

  • Use the source pane to swap hard-coded colors for currentColor so an icon inherits text color in your UI.

  • Big byte size with only a few shapes usually means embedded raster data or excessive path precision: optimize it.

Your privacy is built in

Your SVG is rendered and analyzed entirely in your browser using the native DOMParser. It is never uploaded to any server. The live preview additionally strips scripts, foreignObject, on* handlers and javascript: URLs before rendering, so opening an unknown SVG can't execute code. Nothing is stored, logged or transmitted. Close the tab and every trace is gone.
