SVG Optimizer

About This Tool

Minify SVG files without visual changes: strips editor metadata, empty groups, unused definitions and rounding noise, then rewrites paths at precision you control. Typical savings are 20-50% on designer-exported SVGs — directly improving page speed since SVGs load on every page they appear. The optimizer preserves visual fidelity: a before/after side-by-side at multiple zoom levels lets you confirm nothing shifted before downloading.

How to Use This Tool

1. Drop your .svg (one or several).
2. Choose decimal precision: 2 is the standard sweet spot, 3 for intricate curves, 1 for aggressive minification of simple shapes.
3. Review the savings summary (original vs optimized bytes, removed node counts).
4. Compare the visual preview — original and optimized render side by side.
5. Download the optimized file(s); keep the original as your editable source.

Advantages & Use Cases

Slim icon sets exported from Figma/Illustrator before committing them to a codebase, clean SVGs downloaded from stock sites that carry editor cruft, or reduce a hero illustration from 80 KB to 40 KB. Build pipelines often run this exact step — doing it here shows what it saves.

Supported Formats & Recommendations

• SVG in, SVG out — visual XML structure preserved for further editing.
• Precision 2 drops sub-pixel noise invisible at screen sizes; keep 3+ for SVGs destined to large-format print.
• Text elements stay as text (selectable/accessible); converting text to paths happens in the design tool if needed.

How We Test This Tool

Releases optimize a 15-file corpus (Figma export, Illustrator export, hand-written, stock downloads): rendered pixels must match the original at 1x and 8x zoom, all ids referenced by must survive, and file size must decrease on every file with no XML validity errors.

Frequently Asked Questions

Will optimization change how my SVG looks?

Not visually at precision 2 — paths round to hundredths of a pixel. Always eyeball the side-by-side preview, especially for calligraphic strokes and tiny text.

Why is my optimized SVG still large?

Huge embedded base64 images inside the SVG are the usual cause — extract and reference them as separate assets, or simplify the artwork. The summary shows where the bytes live.

Can I optimize SVGs with scripts or animations?

Animation elements survive, but scripts are stripped for safety. If your SVG relies on embedded JavaScript, optimize a copy and diff carefully.
