What is SVG Cleaner?
SVG Cleaner is a free tool that strips the XML declaration (<?xml version="1.0"?>), DOCTYPE declaration, and leading comments from the top of an SVG file — metadata that isn't needed for the actual artwork but breaks uploads on some platforms. SVG files exported from tools like Illustrator, Figma, svgrepo.com, or Flaticon often include this metadata automatically, and platforms like Blogger can flatly reject an image upload if it's present. This tool picks out exactly that problematic code and removes it while leaving the real artwork untouched.
How to Use
Drag and drop the SVG files you want to clean, or use the choose file button — you can upload several at once. Each file is analyzed and cleaned automatically the moment it's added, showing exactly what was removed (XML declaration, DOCTYPE, leading comments) and how the file size changed. Click Save to download the cleaned file under its original name. If you only have a code snippet rather than a file, expand "Paste code directly" below to clean text instead.
When This Comes in Handy
- When an SVG icon from svgrepo.com or Flaticon won't upload to Blogger
- When an SVG exported from Illustrator or Inkscape won't preview on a particular CMS
- When you want to strip unnecessary metadata before pasting SVG code inline on a webpage
- When you need to clean up a batch of SVG icon files at once
Frequently Asked Questions
- Why won't my SVG upload to Blogger or some CMS platforms?
- Some platforms reject SVG files that start with an XML declaration (<?xml version="1.0"?>), a <!DOCTYPE svg ...> declaration, or leading comments. SVGs exported from icon sites like svgrepo.com and Flaticon, or from illustration software, almost always include this metadata automatically, which is why the problem shows up so often.
- Does this tool damage the actual artwork in my SVG?
- No. It only removes the XML declaration, DOCTYPE, and leading comments — the shapes, paths, and colors inside the <svg> tag are left completely untouched.
- Can I clean multiple files at once?
- Yes. Upload several SVG files together and each one is cleaned independently, with its own save button.
- Is my uploaded SVG sent to a server?
- No. Everything is processed entirely in your browser — files are never uploaded or stored anywhere.
- What happens if I upload an already-clean SVG?
- You'll just see a message that there's nothing to remove, and you can still save an identical copy if you'd like.
