SVG Sprite Builder
Combine self-contained SVG icons into one reusable symbol library. Preview every icon and get unique IDs, preserved viewBoxes and ready-to-copy HTML.
1. Add icons & name the library
No icons selected. New selection replaces the current batch.
Static, self-contained artwork only. Scripts, external resources, animation and unresolved references are rejected. Supported CSS is inlined and classes removed. Icons need a viewBox or numeric dimensions. Limit: 20 icons / 256 KiB each / 2 MiB total / 20,000 total nodes.
2. Preview icons & export
Use the copied snippets on an HTTP(S) website with sprite.svg next to the page. If you inline the library, hide its root and change href to #symbol-id. Give each visible icon an appropriate label, or mark decorative icons aria-hidden.
Ready. Try the example to see how it works.
Using SVG Sprite Builder
Build a reusable SVG icon library while avoiding collisions between internal IDs.
- Choose static self-contained SVG files or try the sample icons. A new file selection replaces the current batch; you can edit the selected source.
- Set a short symbol prefix and build the sprite. Review each icon preview and the integration notes.
- Download sprite.svg or the ZIP pack. Copy a use snippet into your site and test it with your project CSS.
Example
The two sample icons both use an internal paint ID. The builder rewrites them into separate IDs. A generated symbol such as icon-orbit can be used through href="sprite.svg#icon-orbit".
Questions & answers
What is an SVG sprite?
It is a file containing reusable symbol definitions. A use element selects a symbol by its ID. The sprite itself is a library, not a visible sheet of images.
How are ID collisions avoided?
Symbol names are made unique from filenames, and each icon’s internal IDs, paint references, hrefs and supported accessibility references are rewritten together.
Can I include CSS-based icons?
Supported stylesheets are inlined and class names removed. If CSS remains unsupported or cannot be safely inlined, the tool stops rather than silently dropping it. Your page CSS can still affect SVG rendering.
Which artwork is rejected?
Scripts, active HTML, external resources, animation, linked artwork and unresolved local references. Static embedded raster images use the existing image validator.
Why does an external use snippet fail from a file on my desktop?
Browsers can restrict external SVG references opened through file URLs. Serve the files over HTTP(S), or inline the symbol library and use local #id references.
Are accessibility labels preserved?
Existing title/description elements and supported ID references are retained and rewritten. The generated visible-use snippet includes a filename-based label that you should replace with a useful description.
Are SVG files uploaded?
Validation and sprite generation run locally in a worker with the existing SVG library. Artwork is not uploaded for processing; site advertising and analytics follow the privacy policy.
