3 SVG Sprite Generators, Compared Honestly

Forty icons, forty <img> tags, forty network requests. Or one sprite file containing forty <symbol> elements, referenced by ID, styled with CSS, cached once.

The sprite approach has been the sensible answer for years and remains slightly annoying to produce by hand: each icon needs wrapping in a <symbol>, given a stable ID, and having its viewBox preserved while its width and height are stripped. Miss the viewBox and the icon renders at the wrong size; miss the fill removal and it ignores your CSS colour.

How to judge a sprite generator

Are the IDs stable and predictable? You reference icons by ID from markup. If regenerating the sprite renames them, every reference breaks.

Does it strip dimensions and fills? Hardcoded width, height and fill attributes are what stop a sprite icon from inheriting size and colour.

Does it stay on your machine? Icon sets are often licensed or unreleased brand assets.

What comes out besides the sprite? Usage markup, a manifest of IDs, or CSS all save a step.

The comparison

Facts checked August 2026; tools change. Table covers only the 3 alternatives — our tool gets its own section below.

All SVG Icons Sprite Maker

The most thoughtful about IDs, which is the part that bites later. It generates stable symbol IDs with a customisable prefix and a choice of naming format — kebab-case, snake_case and others — and lets you rename items or regenerate IDs before exporting. It also outputs a JSON manifest mapping each symbol ID to a clean output filename, which is genuinely useful if a build step or a component library needs to know what is in the sprite.

You can upload files or paste SVG markup directly, and generation runs in your browser with files and pasted markup staying on your device. Free, no account.

Fixie Tools

The cleanest workflow for the common case. Add your SVGs, adjust settings, and get sprite code plus HTML usage examples you can copy directly — with two options that matter more than they sound: “Remove fills” and “Strip dimensions”, the exact two things that stop sprite icons inheriting CSS colour and sizing.

It runs entirely client-side with an explicit no-upload, privacy-first position, and states free with no signups and no ads. There is less control over ID naming than All SVG Icons offers, so if your sprite needs to match an existing set of references, check what it produces first.

Aspose SVG Sprite Generator

The one offering a real choice of sprite type. It produces either an inline sprite designed to be embedded directly in an HTML document — no extra network request at all — or a linked sprite usable from HTML or CSS as a separate file. That distinction genuinely matters: inline is faster for a small critical set, linked is better for a large library you want cached.

Free and drag-and-drop. Unlike the other two, files are uploaded, with the service stating uploads are deleted after 24 hours and download links expire. For a public icon set that is fine; for unreleased brand assets, prefer a client-side tool.

SVG Sprite Generator

Ours merges several SVG icons into a single sprite of <symbol> elements with stable IDs and preserved viewBox values, and hands back the <use> markup to reference them. Preserving the viewBox while producing the matching use snippets covers the two mistakes that actually break sprites — an icon rendering at the wrong scale, and markup that references an ID slightly differently from the one generated.

What it does not do: emit a JSON manifest, offer inline versus linked variants, or produce CSS and PNG fallbacks. For a build pipeline that needs a manifest, All SVG Icons fits better. MDN’s <symbol> documentation explains why viewBox on the symbol is what makes the whole approach work.

Which one to pick

• A build step that needs a manifest — All SVG Icons.
• Icons that must inherit CSS colour — Fixie Tools’ fill stripping.
• An inline sprite embedded in the page — Aspose, if uploading is acceptable.
• Symbols plus ready-to-paste use markup — the tool below.

How to do it with SVG Sprite Generator

1. Open the SVG Sprite Generator and add your icons.
2. Check the generated IDs — decide on a naming convention now rather than after you have written the references.
3. Confirm each symbol kept its viewBox; that is what makes icons scale correctly.
4. Copy the use markup and set colour with CSS fill rather than in the SVG.

The walkthrough is in how to combine SVG icons into one sprite. Other design tools are in the tools directory.

The SVG to PNG Converter handles the raster fallback if you still need one for email or older contexts.

For generating shapes rather than assembling them, the SVG Blob Generator is in the same family.

Frequently asked questions

Is there a free SVG sprite generator that doesn’t upload my icons?

Yes. All SVG Icons, Fixie Tools and ours all state that generation happens in your browser. Aspose uploads files and deletes them after 24 hours, which is a reasonable policy but still an upload.

Why does my sprite icon ignore my CSS colour?

Because the original SVG has a hardcoded fill attribute, which wins over your stylesheet. Strip fills during generation and set the colour in CSS, using currentColor if you want icons to follow the surrounding text colour.

Why do my icons render at the wrong size?

Usually a missing viewBox on the <symbol>, or leftover width and height attributes on the source SVG. The viewBox defines the coordinate system that lets an icon scale; fixed dimensions override whatever size you set in CSS.

Final thought

Decide the ID naming convention before you generate anything. The sprite is easy to rebuild; the forty references scattered through your templates are not.
