Does it add strokes to filled-only shapes?

No. It edits elements that already have a stroke.

Can I choose custom stroke values?

The first version uses fixed defaults. Custom controls can be added later.

Does it preserve fill colors?

Yes. It only changes stroke-related attributes.

Is SVG Stroke Editor free?

Yes. SVGKit tools are free to use with no account required.

Does SVG Stroke Editor upload my files?

No. The tool runs entirely in your browser, so your files never leave your device.

Will edits survive being reopened elsewhere?

Yes. The output is standard SVG, so any editor, browser, or build step reads the same result.

Can edits break references?

Renaming or removing elements can affect IDs that CSS or animation targets reference. Check those references before shipping major changes.

Does it work on any SVG?

Standards-based SVG works best. Files with active content are sanitized on import.

Best use case

Use it for quick icon and line-art cleanup when exported strokes need a consistent look.

SVG Stroke Editor edits real SVG structure — what you change on the page is what lands in the file.

What you can change

SVG Stroke Editor edits real SVG structure — elements, attributes, and values as they exist in the document — so what you change on the page is what lands in the file.

Edits are real SVG

Nothing is converted into a proprietary format along the way. The result remains standards-based markup that renders the same in browsers, editors, and build pipelines.

Drafts, undo, and safety

Changes stay local with undo support, and active content such as scripts stays blocked. Your working state lives in the browser, never on a server.

Export quality

Exports are clean SVG without editor metadata, so the file you download is the file you edited — ready for production or for another SVGKit tool.

How to use

Paste SVG. Paste SVG markup with stroked elements.
Apply stroke edit. The tool sets stroke width, linecap, and linejoin defaults.
Copy SVG. Copy the stroke-edited SVG.
