A free SVG optimizer that shrinks your files right in the browser. Drop in an SVG or paste its code to strip editor data, round long numbers and shorten paths, then compare the sizes and check that the artwork looks exactly the same before you download it. Nothing is uploaded.

SVG up to 10 MB · converted in your browser, never uploaded
Your SVG is converted on this device and never uploaded. External fonts and images in the file are not loaded.
Design apps save far more than the picture: editor settings, metadata, hidden layers and numbers with six or more decimal places. None of it changes what you see, but all of it costs bytes. An SVG optimizer strips that overhead automatically and leaves the drawing untouched.
Every kilobyte of an SVG logo, icon or illustration is downloaded before it can be drawn. Smaller files load faster on phones, improve Core Web Vitals and make inline SVG in HTML and CSS easier to manage. On a page with dozens of icons, the savings quickly add up to a noticeably faster first view.
Optimized SVG code drops editor namespaces, empty groups and unused definitions. What remains is short and readable, which helps when you change colours by hand, animate parts with CSS or paste the code into a component.
Marketplaces, website builders and icon libraries often cap file size. Removing data that does not affect the artwork is the safest way to get under a limit without touching the design itself. Running files through an SVG optimizer before upload is often enough to pass a 100 KB or 1 MB rule.
Many online tools only shrink the file. This one also shows you whether anything changed, so you can trust the result.
The original and the optimized file are both drawn at 512 pixels and compared pixel by pixel. If nothing visible changed, you see a clear confirmation; if detail was lost, you see how much and can raise the precision.
Choose how many decimal places to keep, whether ID names must stay as they are, and whether the output should be indented for reading. Everything else uses SVGO's tested default preset, with the viewBox always kept for responsive scaling. That keeps the SVG optimizer predictable: the same file and settings always give the same result.
This SVG optimizer runs the open-source SVGO engine inside your browser, so files are never uploaded. Scripts and external links are removed as well, and there is no sign-up, watermark or limit.
The SVG optimizer usually finishes in less than a second, and you can try different settings on the same file as often as you like.
Drop an .svg file of up to 10 MB onto the box above, click Choose SVG, or paste SVG code into the text box and click Optimize code.
See the original size, the optimized size, the percentage saved and the gzipped size. If the check reports a visible change, choose more decimal places; for icons and logos you can often try fewer. The previews of both versions sit side by side, so you can also judge the result with your own eyes.
Click Download optimized SVG to save it as name.min.svg, or Copy code to paste the result straight into HTML, CSS or a component file.
The optimizer removes overhead; these habits remove the rest. Combine them with the SVG optimizer for the smallest possible files.
Traced artwork and hand-drawn shapes often contain many more points than they need. Using Simplify in your design app first, then optimizing here, usually saves far more than either step alone. Fewer points also mean smoother cuts on Cricut and laser machines and faster rendering in browsers.
A bitmap pasted into an SVG is stored as long base64 text and is not recompressed by the optimizer. Link a separate WebP or JPG, or keep photos out of icons and logos altogether. If a logo must contain a photo, compress that photo before placing it.
SVGs created by our AI PNG to SVG converter are already cleaned and optimized as part of the conversion, so they are ready for cutting machines and websites straight away.
