Free SVG Optimizer

Drop in an SVG — or a whole ZIP of them — and shrink it safely. Strips Illustrator and Inkscape cruft, rounds coordinate precision and minifies the markup, then shows you exactly how many bytes you saved. It never breaks your file, and nothing is ever uploaded.

Launch the SVG optimizer How it works
100% in your browser — your SVG files are never uploaded to a server.
Why use it

Smaller SVGs, the same graphic.

Design-tool exports are full of invisible bloat. This tool cleans it out without changing how your icon or logo actually looks.

Strip editor cruft

Removes comments, <metadata>, Illustrator and Inkscape/Sodipodi elements & namespaces, data-name attributes and the XML declaration and DOCTYPE.

Round precision

Trims long decimal path and coordinate numbers to a precision you choose (0–4 decimals) — adjustable per file with a live slider.

Minify markup

Collapses whitespace between tags and minifies inline <style> blocks and style= attributes for a tighter file.

Never breaks it

If any step would produce an invalid, empty or larger file, it keeps your original untouched. It never ships an SVG that got bigger.

How it works

Three steps, all in your browser.

1

Drop your SVGs

Drag in one SVG, a batch of them, or a .zip of SVGs. Everything is read and processed locally — nothing is uploaded.

2

Tune the options

Toggle what gets stripped and set the rounding precision — per file or all at once. Each card shows the before → after saving live.

3

Download or copy

Save any single optimised .min.svg, copy its code to the clipboard, or export the whole batch as a ZIP.

Why ours

Built to be safe and private.

Ad-safe by default

Your width, height and viewBox are preserved so the graphic renders the same. Every file falls back to the original if optimising would risk it.

See what you saved

Each SVG shows its before → after size and percentage saved, plus a total across the batch. Files that are already tight are simply left alone.

Private by design

Everything runs locally with no library and no server — your SVG files never leave the browser. Optimising, single downloads and copying code are free and unlimited.

Free vs Pro

Free to use, fair on downloads.

Optimising and previewing are always free and unlimited. The only limit is on the batch ZIP export.

FAQ

Quick answers.

Are my SVG files uploaded to a server?
No. The SVG Optimizer runs 100% in your browser — every file you drop in is parsed and minified on your own device and never leaves it. That makes it safe for unreleased logos, icon sets and confidential brand assets.
Can it break my SVG?
It's built not to. Every file is optimised with a safety net: if anything goes wrong during parsing or minifying, or the result would be empty, invalid or larger than the original, the tool quietly keeps your original file untouched. It also never ships an SVG that got bigger — if a file is already lean, it's left as-is and labelled “already lean”.
What exactly does it strip and shrink?
It removes editor cruft that bloats exported files — comments, <metadata> blocks, Illustrator and Inkscape/Sodipodi elements and namespaces (inkscape:, sodipodi:, dc, cc, rdf), data-name attributes, and the XML declaration and DOCTYPE. It also rounds coordinate and path numbers to a precision you choose, collapses whitespace between tags, and minifies inline <style> blocks and style= attributes.
Will it change how my SVG looks or its dimensions?
By default it preserves your width, height and viewBox, so the graphic renders the same. Rounding precision is adjustable per file (0–4 decimals) so you decide how aggressive to be. There's also an optional switch to drop the fixed width/height for responsive use — it's off unless you turn it on.
Can I optimise a whole batch at once?
Yes. Drop in many SVGs or a .zip of SVGs and it optimises them all, showing a before → after byte saving for each one and an overall total. You can download any single file or copy its code for free; batch “Download all (ZIP)” exports use a free daily limit.
Is it free?
Yes — free to use with no signup. Optimising, previewing savings, downloading a single file and copying the minified code are always free and unlimited. Only the batch ZIP export uses a free daily limit of 5 exports per day; a Premium account makes those unlimited. Working with other assets? Try Convert Image or the HTML5 ZIP Optimizer.

Shrink your SVGs — free.

Free to use with no signup, and nothing is ever uploaded. Strip the editor cruft, round the precision and minify the markup — optimising, single-file downloads and copying code are unlimited, and Premium unlocks unlimited batch ZIP exports.
