Free Online SVG Image Compression

Smaller SVGs, just as crisp

ImageTool.app's online SVG compressor cleans up SVG code and removes redundant data to shrink file size without affecting how it renders. Everything runs locally — no upload required.

Choose Image

SVG is essentially text code, and design tools often export SVGs bloated with redundancy — editor comments, extra metadata, excessive coordinate precision and hidden layers. ImgZilla trims this redundant code locally to shrink size without affecting how it renders — files are never uploaded to any server.

Why SVG compression is different

Vectors never blur

SVG is vector graphics — crisp at any scale. Compression only trims code, never sacrifices quality.

Clean up redundant code

Automatically removes editor comments, useless metadata, empty groups and hidden elements for a cleaner, lighter file.

Trim path precision

Reins in excessive coordinate decimals to a sensible range, noticeably shortening path data with no visible difference.

Better for inline and web

Smaller SVGs inline into HTML without bloat, load faster and help your Core Web Vitals.

How to compress SVG

1

Drop in an SVG

Works with icons and illustrations exported from Figma, Sketch, Illustrator and more.

2

Export the SVG

Still standard SVG, renders identically, but with leaner code and a smaller file.

FAQ

Will compression change how the SVG looks?

No. Optimization only removes redundant code and trims precision; the rendered graphic stays visually identical to the original.

How small can an SVG get?

Design-tool exports typically shrink 10–30%, depending on the redundant data and path complexity.

Will it break animation or interactivity in the SVG?

The default cleanup preserves necessary ids, classes and animation structure; if in doubt, you can re-verify after compression.

How is it different from compressing JPG or PNG?

SVG is vector text, so it compresses code rather than pixels — the result is lossless and infinitely scalable, whereas bitmap compression targets pixel data.
