Try It FreeReplace 5 tools with one upload
Crop, clean, vectorize, theme, and export automatically
Precision SVG Vectorization
Powered by VTracer (Rust compiled to WebAssembly). Choose spline, polygon, or pixel mode. Live before/after comparison slider.
20 Favicons, One Click
9 PNGs, 9 Apple Touch Icons, 1 ICO, plus a manifest. Ready for legacy, iOS, and PWAs.
100% Private
Every pixel is processed in your browser via WebAssembly. Zero server uploads.
Social-Ready Images
Perfect dimensions for Facebook, Twitter, LinkedIn, and Instagram. Plus a complete structured brand kit directory.
Auto-Crop & Center
Detects logo bounds, removes excess whitespace, and optically centers — not just geometric center.
Smart Upscale
Logos under 512px are auto-upscaled to 2048px via iterative high-quality interpolation for vastly better vector tracing.
Background Removal
Edge-based flood fill strips solid backgrounds with configurable tolerance. Works on white, colored, or gradient backgrounds.
Refinement Tools
Real-time adjustment sliders for brightness, contrast & sharpness. Click any color to replace it or make it transparent.
Works in dark mode. Automatically.
Your logo should work everywhere.
currentColor
Converts all fills to fill="currentColor". The SVG automatically inherits the parent text color.
Smart currentColor
Only converts near-black/white. Brand colors stay untouched. Red icon + black text? Text adapts, icon stays red.

FAQ
Common Questions
No. Never. All processing happens inside your browser using WebAssembly. You could disconnect Wi-Fi after the page loads and it would still work perfectly.
Upload: PNG, JPG, WebP, GIF. Output: SVG, PNG (multiple resolutions), ICO, and JSON (webmanifest). For best results, use a high-res PNG with transparent or solid background.
We use VTracer, a Rust tracing engine compiled to WebAssembly. It analyzes bitmap edges and converts them to vector paths. Choose spline (smooth), polygon (sharp), or pixel modes and adjust detail with a live preview.
