Why it happens
The halo comes from the old background
Around every edge of a logo image, the pixels are a blend of the logo and its background. Cut it out and those blended pixels come along, so a logo taken off white shows a light fringe on a dark header.
An SVG gives you editable shapes with clean boundaries. Remove background leaves the surrounding area transparent while keeping enclosed details of the same color.
Step by step
Remove the background in four steps
Use a high-contrast logo image
A logo on a plain background separates most cleanly. If the logo already sits on transparency, it stays transparent.
Convert it to SVG
Upload the image and check the edges in the preview.
Turn on Remove background and download
Use Remove background under Download options before saving the SVG. It removes the outer background and keeps enclosed details of the same color. The preview stays unchanged; check the downloaded file in your editor.
Export what you need
Keep the SVG for print and the web, and export transparent PNGs from it for tools that need an image.
Before you use it
Check it on a dark and a light background
- Place the logo on a dark color and on white to make sure no edge fringe is left.
- Check inside letters and closed shapes. Enclosed background-colored areas are kept as pieces; remove those in your editor if you want them to be transparent.
- If the logo had a drop shadow, decide whether to keep it. It comes back as a separate shape you can delete.
Good to know
When this works best
- Logos on plain or simple backgrounds work best. A logo placed over a photo needs the photo removed first.
- Details that meet the outer background can disappear with it. A transparent original or a contrasting background helps keep those parts distinct. If download options are unavailable, choose Original with the background kept and edit the SVG manually.
