Quick answer: SVG Optimizer — Shrink SVG files Free, no signup, runs in your browser. See below for the interactive tool, 4-step guide and FAQs.
Paste SVG code, strip comments, collapse whitespace, remove empty attributes and shorten hex colors. Preview is sanitized before rendering.
Preview will appear here after optimization. Dangerous content like scripts and event handlers is stripped before rendering.

Comments, whitespace between tags, empty attributes, default fills and verbose precision collapse safely entirely offline. Long hex codes like #aabbcc shorten to #abc without visual change. For example a 12.4KB Figma export drops near 8.1KB after one pass. Scripts strip before preview for safety with pastes up to 1MB.
Yes. Scripts and event handlers strip before rendering, so pasted markup cannot execute while previewing shapes locally. A 12.4KB icon set cleans to 8.1KB with live vector preview and byte savings displayed. All parsing stays in-tab, ideal for third-party marketplace icons of uncertain provenance requiring caution.
Pastes near 1MB process smoothly on desktop, while larger files should split for responsiveness on phones. Vector paths remain intact; embedded base64 images persist but limit savings substantially. For example 850KB illustrations with raster effects shrink modestly, whereas pure icons collapse dramatically. All work remains local offline.
Embedded base64 JPEGs, excessive decimal precision and raster effects dominate bytes that whitespace removal cannot reclaim. Compare 12.4KB icons saving 35 percent against 900KB posters with photos saving 3 percent. Re-export vectors without embedded images, convert photos separately, then reoptimize for meaningful reductions across gray documentation themes.
This builder handles one paste per run for focused review of savings and preview accuracy. For icon systems, process marks sequentially and track 12.4KB to 8.1KB wins in a spreadsheet before committing. For raster export of cleaned vectors, render PNGs on the SVG to PNG tab above after minification completes locally.
Minify SVG markup by removing comments, inter-tag whitespace, empty attributes and redundant precision entirely offline in your browser. Paste Figma exports starting with svg tags to see live byte savings and safe vector preview instantly. Example 1: clean a 12.4KB navigation icon to 8.1KB by collapsing whitespace and shortening #aabbcc to #abc. Example 2: tidy a 45KB illustration set to 31KB by dropping editor metadata and default fills. Developers shrink icon systems, designers clean handoffs, and bloggers accelerate pages without altering appearance. Scripts and event handlers strip before rendering for security, while pastes up to 1MB process smoothly. Workshops demonstrate savings on projectors spanning several meters, building intuition for production hygiene across teams and semesters with measurable outcomes and printed checklists for code reviews and release audits.
Exporters inject readable formatting that browsers ignore, creating easy wins for minifiers operating locally. Table — Bloat | Saving on 12.4KB | Risk: XML comments | 1.2KB | none; whitespace indent | 1.8KB | none; empty attributes | 0.6KB | none; #aabbcc to #abc | 0.4KB | none; editor metadata | 0.3KB | none. Pure icons often shed 30 to 40 percent, while files with embedded base64 JPEGs save under 5 percent because raster payloads persist. Vector paths stay geometrically identical; only serialization tightens. Split 2MB posters for phone responsiveness, processing sections sequentially. Instructors compare before and after markup side by side to teach semantic versus presentational attributes across gray code editors and documentation pages while logging precision settings for future icon system updates.
Code minification cannot trace rasters, batch queues or rewrite illustration structure for semantic perfection. Edge case: hand-optimized sprites using precise 3-decimal coordinates can shift subpixel rendering on low-density displays when rounded aggressively, requiring visual diffing at 100 percent zoom before deployment across browsers. Limitation: single paste per run, without image tracing or font outlining for complete portability. For crisp PNG fallbacks from cleaned vectors, export on the SVG to PNG tab above. For photo payloads inside vectors, compress sources at /image-compressor first, free offline with nothing uploaded. Teams archive originals while shipping minified derivatives to production repositories while documenting cleaning steps for teammates handling future icon deliveries and updates and automated checks that flag regressions before releases while preserving gray theme previews for reviewers.
