This SVG Optimizer strips out the bytes that don't affect how an SVG renders — XML declarations, DOCTYPE headers, comments left behind by design tools, <title>/<desc>/<metadata> elements, and redundant whitespace between tags — leaving the visual output identical while shrinking the file. Paste your SVG markup and get a cleaned-up version instantly, along with the exact byte size before and after. It's a lighter-weight, transparent alternative to a black-box optimizer: every transformation it applies is visible and reversible-in-principle, so you can trust nothing structural was changed. Everything runs locally in your browser — your SVG markup is never uploaded. Scroll down to paste your SVG.
Features
- Strips comments, XML declarations, and DOCTYPE headers
- Removes editor metadata (<desc>, <metadata>) and optionally <title>
- Collapses redundant whitespace while preserving <text> content
- Toggle each cleanup individually to control what gets removed
- Live before/after preview so you can confirm nothing changed visually
- Shows exact byte size before and after, plus the percentage saved
- Paste markup or drop an .svg file straight in
- Runs entirely client-side, nothing uploaded
Why use this svg optimizer?
- Smaller SVG files load faster on your site
- Transparent, predictable transformations (no surprises)
- Fully private — your icons never leave your browser
- Free with unlimited use
Frequently asked questions
Does this change how my SVG looks?
No. Every transformation removes only bytes that do not affect rendering — comments, metadata elements, and whitespace between tags. Text inside <text> and <tspan> keeps its spacing because those are rendered glyphs, and the before/after preview lets you confirm the result is identical.
How does this compare to a tool like SVGO?
This is a lighter, regex-based cleanup covering the most common wins (comments, metadata, whitespace); a full AST-based optimizer like SVGO can also recompress path data and merge paths for deeper savings on complex icons.
Is it safe to run this on icons with a <title> used for accessibility?
Removing <title> is a toggle you control, and it is on by default. <title> is often the accessible name a screen reader announces, so switch that cleanup off to keep it — or leave it on and label the icon with an aria-label where it is used.
Will this break gradients or clip-paths that use IDs?
No, ID references and their targets are left untouched — only comments, metadata, and whitespace are removed, not attributes or element structure.
Can I optimize multiple SVGs at once?
No, this tool processes one SVG at a time; paste each one individually for now.
