Drag and drop an SVG file here, click to browse, or paste SVG markup directly.
Why optimize SVG files?
Faster Load Times
SVGs exported from design software like Figma or Illustrator contain metadata, empty groups, and unnecessary precision. Optimizing them strips away the bloat, significantly reducing file size.
Cleaner Markup
Optimization simplifies complex paths, merges redundant CSS styling, and collapses groups, making the raw SVG code much easier to read and maintain for developers.
Security & Privacy
SVGs can contain hidden JavaScript, event handlers, and editor metadata (like computer usernames). Stripping this data makes your SVGs safer to use on production websites.
Responsive Ready
Our recommended mode intelligently preserves critical accessibility attributes like viewBox and title, ensuring your icons scale perfectly on any device.

Frequently Asked Questions
What is SVGO?
SVGO (SVG Optimizer) is an industry-standard Node.js-based tool for optimizing SVG vector graphics files. Our tool runs the SVGO engine directly in your web browser.
Will optimization change how my SVG looks?
Our "Recommended" mode is designed to be visually lossless, meaning your SVG will look completely identical. If you use "Custom" mode and heavily reduce the numeric precision, curved paths may become slightly jagged.
Why is my SVG size not reducing by much?
If your SVG is already very clean (for example, if it was hand-coded or already exported tightly from an icon library), there might not be much bloat to remove!
Does this tool preserve accessibility tags?
Yes! The Recommended mode automatically preserves the <title> tag and the viewBox attribute so your icons remain accessible to screen readers.
