SVG Icon Generator, Build & Normalize a Consistent Icon Set
Drop in a pile of mismatched SVGs and pull out one clean, consistent icon set: same viewBox, same size, one currentColor that recolors from CSS. Or build a fresh icon from a shape preset. Everything runs in your browser, nothing is uploaded.
What is the svg icon generator?
The SVG Icon Generator normalizes a batch of mismatched SVGs into one consistent set with a uniform viewBox, size, stroke and currentColor, then exports a <symbol> sprite or each cleaned icon. It can also build simple icons from shape presets. Free, in-browser, and nothing is uploaded.
The GigAI SVG Icon Generator fixes the single most annoying thing about hand-collected icons: they never match. One is 20×20, the next is 512×512, one is hard-coded #333, another is a blue stroke, and a third refuses to recolor from CSS. Paste or drop your SVGs and the tool forces the whole batch onto one shared viewBox and export size, rewrites fixed fills and strokes to `currentColor` so every icon inherits its color from a single CSS `color` property, and unifies stroke width across the set: then shows you the entire collection on a live grid so you can eyeball consistency at a glance. When you like what you see, export a single `<symbol>` sprite you reference with `<use href="#id">`, or download the cleaned SVGs to drop straight into your components. Need a shape that doesn't exist yet? Switch to Build mode and mint a fresh icon from a geometric preset (star, hexagon, gear, heart, burst, triangle or polygon) with controls for sides, rotation, radius and a solid or gradient fill. Because the normaliser and the shape geometry are pure and deterministic, the same input and settings always produce the same output, so a set you approve regenerates byte-for-byte later. Nothing is uploaded, parsing, retinting, the grid preview and the sprite are all computed locally, so it works offline and never sees your brand marks.

How to use the svg icon generator
- 1
Choose Normalize or Build
Normalize takes a batch of existing SVGs and makes them consistent. Build mints a new icon from a shape preset. Switch modes anytime with the toggle.
- 2
Add your icons (Normalize)
Paste one or more SVGs, separated by blank lines, or drop.svg files. Each becomes an entry in the set. The grid preview updates live.
- 3
Set the shared grid
Pick the export size and viewBox, toggle currentColor retinting, and unify stroke width. Every icon in the batch snaps to the same settings.
- 4
Preview & pick a format
Check the grid on light/dark/checkerboard. When it looks right, export a <symbol> sprite, copy the markup, or download the cleaned SVG / PNG.
- 5
Or build from a preset
In Build mode pick a shape, dial sides, rotation and fill, and download the fresh icon, already on the same clean grid as the rest of your set.
What SVG Icon Generator includes
One viewBox & size for the whole set
Force every icon onto a single shared viewBox and export size (16, 20, 24, 32, 48…) so a set collected from a dozen sources finally lines up on the same grid.
Retint to currentColor
Rewrite hard-coded fills and strokes to `currentColor` so each icon inherits its color from CSS, one `color` property recolors the entire set, including hover and dark mode.
Live grid preview of the batch
See every icon at once on a checkerboard, light or dark grid. Spot the one that's off-size, mis-colored or clipped before you ship, not after.
Export a <symbol> sprite
Combine the cleaned icons into a single SVG sprite of `<symbol>`s with a copy-paste `<use href="#id">` snippet: one request, cached, referenced anywhere on the page.
Build icons from shape presets
No source SVG? Mint one from a geometric preset (star, hexagon, gear, heart, burst, triangle, polygon) with sides, rotation, radius and solid or gradient fill.
Deterministic, copy, download, export
Same input, same output, always. Copy the markup, download the sprite or SVG, or rasterise a transparent PNG, all generated locally with undo/redo and shortcuts.
Why use our svg icon generator
A set that actually looks like a set
Stop shipping icons that are three sizes and four colors. One click puts every mark on the same grid and the same currentColor, so your UI reads as intentional instead of scavenged.
Recolor everything from one CSS property
Once fills are currentColor, a single `color` on a parent restyles the whole set (active states, hover, dark mode) with zero per-icon edits and no icon font to rebuild.
One sprite instead of many requests
Ship a single `<symbol>` sprite and reference each glyph with `<use>`. Fewer network round-trips, browser-cached, and every icon stays crisp, scalable SVG.
Private, offline, reproducible
Parsing, retinting and the sprite are computed in your browser from deterministic rules. Nothing is uploaded, and the same set regenerates identically whenever you need it.
Built for the way you work
From quick one-off fixes to daily workflows, see how people put this tool to use.
- Design systems engineer
Unify a scavenged icon set
Icons pulled from Figma, a UI kit and three npm packages never match. Normalize them all to a 24×24 viewBox and currentColor so the whole library recolors from one token.
- Frontend developer
Ship a single SVG sprite
Bundle your cleaned icons into one `<symbol>` sprite and reference them with `<use>`, fewer requests, cache-friendly, and no icon-font pipeline to maintain.
- Product designer
Sanity-check consistency
Drop the whole set onto the grid preview to catch the icon that's the wrong weight, off-size or a stray hex before it reaches a component and a review.
- Indie hacker
Mint a quick brand glyph
Need a star, gear or hexagon mark right now? Build one from a preset with a gradient fill and download the SVG. No vector editor, no stock licence.

Common problems, solved
Hit a snag? Here are quick fixes for the issues people run into most.
One icon didn't switch to currentColor.
Colors set inside a <style> block, on a gradient stop, or via a CSS class aren't rewritten, the retint targets inline fill/stroke attributes. Move the color to a fill/stroke attribute, or leave that icon's color intentional and recolor it in CSS.
An icon looks clipped or off-centre in the grid.
Its original artwork extends past the viewBox you chose, or it had no viewBox to begin with. Give the source SVG a correct viewBox that tightly bounds its paths, then re-normalize, the tool re-fits it to the shared grid.
My stroked icon got heavier or lighter than the rest.
Unifying stroke width sets every icon to the same value, which changes any that were drawn at a different weight. Turn stroke unification off to keep each icon's original weight, or pick a width that matches most of the set.
The sprite icons don't show when I use <use>.
The sprite `<svg>` is display:none by design, inline it once in your page (or reference it by URL) and each `<use href="#id">` pulls its symbol. Make sure the id in href matches the symbol id and that the sprite is present in the DOM.
Get the most out of it
Pick your viewBox first: 24×24 is the safest default for UI icons. Match whatever your existing components already assume.
Leave retinting on for line/glyph icons, but turn it off for multi-color logos you don't want flattened to one color.
Separate multiple pasted SVGs with a blank line so each is read as its own entry in the set.
Prefer the sprite for many icons on one page and standalone SVGs when you import icons individually into components.
In Build mode, a 6-point star at ~40% inner radius reads as a classic 'spark'. A hexagon with rotation 0 makes a clean badge base.
What's new
Recent updates and improvements to the svg icon generator.
Initial release: batch SVG normaliser (shared viewBox, export size, currentColor retint, stroke unification) with a live grid preview and standalone/sprite export.
Added Build mode: mint icons from geometric shape presets (star, hexagon, gear, heart, burst, triangle, polygon) with sides, rotation, radius and gradient fill.
Added <symbol> sprite export with a copy-paste <use> snippet, undo/redo across settings, keyboard shortcuts, and checkerboard/light/dark grid surfaces.
