SVG Optimizer
Strip editor metadata from Illustrator, Figma, and Inkscape exports. Round path precision. Typical 30-80% smaller files with identical visual output.
Safe — strips editor metadata, comments, empty elements
Upload an SVG to see the optimised version.
What makes an SVG bloated and how to fix it
Every vector editor embeds its own metadata in the SVGs it exports. Adobe Illustrator adds "Generator" comments, font and gradient references that aren't actually used, and rounded display coordinates at 6 decimal places. Inkscape adds its own sodipodi:* namespace on nearly every element. Figma includes data-name attributes, redundant style blocks, and pixel-precise positioning.
None of this is needed for display. When a browser renders an SVG, it ignores every editor-specific attribute. Stripping them out — plus rounding path coordinates from 0.123456789 to 0.12 — typically halves the file size with no visible change. Pair with a Vectorize Studio export and the resulting file is often a tenth the size of the original raster.
Pair with our Vectorize Studio to turn a raster image into SVG, then run it here for the smallest possible vector output. If you're shipping mixed assets to a CDN, the Image Format Converter handles PNG/JPG/WEBP compression alongside this, and the Favicon Generator will feed an optimized SVG straight into every browser-required size without re-bloating it.
What people use this for
Shrink icons for a design system library
Design systems often ship 100+ icons. A 50% size reduction across the whole set means faster page loads for every downstream app using them. Run each icon through Aggressive mode, commit the smaller files.
Clean an Illustrator export before handing to developers
Illustrator exports include "Generator: Adobe Illustrator 27.0" comments and huge metadata blocks that no browser renders. Strip them so your dev team opens a 2 KB file instead of a 20 KB one with identical visuals.
Prepare a logo for email-safe embedding
Emails that inline SVG logos (via data URIs) need the SVG to be tiny or Gmail clips the message. Aggressive mode reliably gets branded logos under the clipping threshold.
Optimise a Vectorize Studio export
Our own vector output is already fairly clean, but a final pass here drops another 10-25%. Natural workflow: raster → Vectorize → SVG Optimizer → deliverable.
Prepare SVG for SVG sprites
SVG sprite sheets (one big file containing many icons) are sensitive to size. Stripping every unused metadata attribute per icon before sprite compilation can halve the sprite total. Use Safe mode to preserve IDs that the sprite targets.
Check that a designer's file is clean
QA step for client deliverables: run their exported SVG through the tool, see how much was stripped. If savings are 70%+, the original export was loose — send back for clean re-export with better settings.
Four steps, no signup
Upload or paste your SVG
Drop an .svg file up to 10 MB, or paste SVG markup directly into the text area. Works on exports from Illustrator, Figma, Inkscape, Vectorize Studio — any standard SVG.
Pick optimisation level
Safe removes only editor metadata (Illustrator, Sodipodi, Inkscape namespaces), comments, and empty attributes. Aggressive additionally rounds numeric precision, removes default attribute values, and collapses whitespace.
Preview before vs after
Side-by-side SVG renders let you verify nothing visible was removed. File-size savings are shown as absolute bytes and percentage.
Download the optimised SVG
Export the cleaned SVG. Drop it directly into your website, Figma library, or client deliverable. Smaller file, same visual output. No watermarks, no signup.
Visible before vs after, fully free
Side-by-side preview means you can trust what changed.
Visual diff
Input and output renders side-by-side. Verify nothing broke before you commit the optimised file.
Two safety levels
Safe for IDs and references that CSS / JS targets. Aggressive for maximum savings when display is the only consumer.
Private, offline
Parsing, optimising, rendering all happen in your browser. Nothing uploads. Safe for brand assets.
Both modes free
No paywall on Aggressive. No signup needed. Paste, optimise, download.
