Mask injection

The tool inserts a mask named svgkit-editable-mask sized from the SVG viewport and applies it to the first renderable element.

Boundary

It is a mask starter, not a visual mask painting editor. Future controls can adjust mask geometry interactively.

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

What you can change

SVG Mask 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

  1. Paste SVG. Paste SVG markup.
  2. Insert mask. The tool adds a defs mask and applies it.
  3. Copy SVG. Use the masked SVG output.

Frequently asked questions

What shape is the mask?
A white rectangle with a centered black circle cutout.
Can I change the mask?
Yes. Edit the generated mask geometry manually.
Does it apply to all elements?
No. It applies to the first renderable element.
Is SVG Mask Editor free?
Yes. SVGKit tools are free to use with no account required.
Does SVG Mask 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.
