SVG Optimizer Online

Optimize up to 20 SVG files in your browser. Compare original and optimized previews, check file sizes, then download each result or a ZIP.

SVG OPTIMIZATION GUIDE

When is SVG optimization useful?

SVG files can contain editor data and markup that are not needed to display the artwork. Minifying them can make files easier to deliver and manage, though the size of each result depends on the source.

Website graphics

Prepare self-contained logos, icons, and illustrations before adding them to a website.

Design handoff

Clean exported SVG markup before sharing files with a developer or teammate.

Several assets at once

Process a set of SVGs, inspect each result, then download the successful files together.

What does this SVG optimizer change?

The tool uses SVGO to remove unnecessary data and simplify markup where possible. Check the preview before using an optimized file.

Optimizes or removes

Editor metadata and comments
Redundant attributes and markup
Path data where it can be simplified

Keeps available

The viewBox for responsive scaling
IDs used within the SVG
Title and description elements

Source SVG

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">
  <title>Mark</title>
  <desc>Sample icon</desc>
  <metadata>Editor data</metadata>
  <!-- Editor note -->
  <path id="shape" d="M 2 12 L 22 12"/>
</svg>

Illustrative result

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">
  <title>Mark</title>
  <desc>Sample icon</desc>
  <path id="shape" d="M2 12h20"/>
</svg>

Conceptual example. The markup and file size of your result will depend on the source SVG.

How to optimize SVG files in bulk

01
Add SVG files
Choose or drop up to 20 SVGs. Each file can be up to 10 MB, with a 50 MB total limit.
02
Review the results
Optimization starts automatically. Follow each file's status, compare sizes, and switch between the original and optimized previews.
03
Download SVGs or a ZIP
Save a successful file on its own, or download all successful results in one ZIP after the queue finishes.

Compare SVG file sizes before and after

Each row compares the original file's bytes with the optimized SVG's bytes. The batch summary totals successful files only.

Smaller

The result contains fewer bytes than the original. Preview it to confirm that the artwork still looks right.

Same size or larger

Already compact artwork may leave little to remove. You can still preview and download the result.

Failed

Invalid SVG or blocked content remains in the list so you can remove it or try again. Failed files are excluded from the ZIP.

Tips for a reliable SVG result

Keep your source file

Optimized markup can be harder to edit in a vector editor. Save the original for future changes.

Inspect important artwork

Compare the preview with your source, especially when the SVG uses intricate paths, masks, or embedded images.

Export a self-contained SVG

Files with scripts, active content, or external references are rejected. An optimizer is not a security sanitizer for arbitrary SVGs.

Need a different output?

Turn a finished SVG into a raster image with the SVG to PNG converter. Prepare a logo in several PNG dimensions with the Logo Resizer.

Frequently asked questions

Are my SVG files uploaded?

No. Files are read, optimized, previewed, and packaged into a ZIP in your browser.

Can optimization change how an SVG looks?

It can in some cases. The optimizer rewrites markup and path data, so inspect the preview and keep your original file.

Why did my optimized SVG get larger?

Some SVGs are already compact, while preserving useful information can offset removed data. The tool reports the actual before and after file sizes instead of promising a reduction.

Can I add more files while the batch is running?

Yes, up to 20 files and 50 MB total. Files are processed one at a time, and duplicates already in the batch are skipped.

What happens to a file that fails?

It stays in the list with an error message. You can try again or remove it; the ZIP contains only successful results.

When should I convert an SVG to PNG instead?

Use PNG when a destination requires a raster image or fixed pixel dimensions. Keep SVG when you need a scalable vector file.
