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.
Privacy-first
Vectorization and asset generation run in your browser via WebAssembly—your logo file isn’t sent to our servers for that work. Accounts, billing, and optional Pro features (cloud sync, hosted brand kits) use the network.
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 high-quality canvas interpolation (Free)—better pixels for tracing. Pro adds optional AI super-resolution in your browser before vectorization.
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. All image processing (vectorization, background removal, favicon generation, OG images) runs 100% in your browser using WebAssembly. Your logo never leaves your device. The only things that use the network are sign-in, billing, optional cloud sync, and Pro hosted brand kits.
Just your email address for authentication and a Stripe customer ID for billing. We do not collect your images, filenames, generated assets, or any behavioral analytics. You could disconnect from the internet after the page loads and the tool would still work.
PNG, JPG, WebP, GIF, and SVG. Maximum file size is 20 MB. For the best vectorization results, start with a high-resolution PNG on a transparent or solid-color background.
From a single logo upload you get: a production-ready SVG, high-resolution PNGs at multiple sizes (256 to 4096px), a complete favicon package (ICO with 16/32/48px plus PNGs from 16 to 512px), social media OG images for Facebook, Twitter, LinkedIn, and Instagram, a PWA splash screen script, an HTML snippet with all the meta tags, and a webmanifest file. Pro users can download everything as a single ZIP brand kit.
Any modern browser with WebAssembly support: Chrome, Firefox, Safari, Edge, and their mobile equivalents. LogoNuri is also installable as a Progressive Web App (PWA) on desktop and mobile for offline-capable use.
LogoNuri uses VTracer, a precision tracing engine written in Rust and compiled to WebAssembly. It analyzes the edges in your bitmap and converts them to clean vector paths. You can choose between three modes: spline (smooth curves), polygon (sharp angles), or pixel (pixel-perfect edges). All settings are adjustable with a live before/after preview.
AI Enhance uses Real-ESRGAN, a neural network that upscales your logo to 4x its original resolution before vectorization. This dramatically improves SVG quality for small or low-res source images. The model runs directly in your browser via ONNX Runtime (WebGPU when available, WASM as a fallback). It processes the image in tiles and shows progress as it goes.
Yes. Paste any website URL and LogoNuri will scan the page for logo images, favicons, and Open Graph images. Pick the one you want and it loads straight into the editor. You can also generate a logo from scratch using the built-in AI generation tool.
Yes. If your logo already has a transparent background, LogoNuri preserves it. If it has a solid background (white, black, or any color), the auto background removal tool detects and removes it with adjustable tolerance. You can also pick any color from the image and remove it manually.
The Free plan gives you full access to SVG vectorization, background removal, color tools, favicon generation, OG image generation, dark mode asset creation, and PWA manifest output. You can download the SVG directly. Free users can save 1 project. No sign-up is required to use the core processing tools.
Pro unlocks: unlimited saved projects, cloud sync across devices, batch import and export, one-click download of your entire brand kit as a ZIP (PNG, favicons, OG images, PWA splash, HTML snippets), direct export to Figma and Canva, unlimited AI 4x super-resolution, AI logo generation, and shareable hosted brand kits.
$9 per month or $59 per year (45% savings). Both plans include the exact same features. Payments are processed securely through Stripe. You can switch between monthly and yearly at any time.
Yes. Cancel from your account settings at any time. You keep Pro access until the end of your current billing period, then your account reverts to the Free plan. Your saved projects and downloaded assets are yours to keep.
No. You can upload a logo, process it, and download the SVG without creating an account. Signing in (via a passwordless magic link to your email) is only needed to save projects, sync across devices, or access Pro features.
Absolutely. LogoNuri is built for designers, developers, and agencies who process logos regularly. Pro users can batch import multiple logos, export full brand kits as ZIPs, and share hosted brand pages with clients. Since processing is local, client logos never touch a third-party server.
Yes. The vectorizer supports full-color output with adjustable color count, gradient handling, and layer stacking. You can tweak noise filtering, corner sharpness, segment length, and other advanced settings to get clean results from detailed or multi-color source images.
When enabled, all fills in the SVG are replaced with the CSS keyword "currentColor." This means the logo automatically inherits whatever text color is set in your CSS, making it trivial to support dark mode, themes, or inline color changes without editing the SVG file. There is also a "Smart" option that only converts black and white fills to currentColor while preserving brand colors.
LogoNuri generates a complete favicon package from your processed logo: a multi-size .ico file (16, 32, and 48px), individual PNGs from 16px to 512px, Apple Touch Icons for iOS devices, and a ready-to-use webmanifest JSON file for PWAs. An HTML snippet with all the link and meta tags is also provided so you can copy-paste it into your site.
Mostly yes. Once the page and WebAssembly modules are loaded, all core processing works offline. You can install LogoNuri as a PWA for an app-like experience. Features that require the network (sign-in, cloud sync, URL import, AI generation) will not work offline, but uploading, vectorizing, and downloading will.
Yes. LogoNuri offers a CLI tool that skips the UI entirely. It auto-detects your project framework, generates all 44+ assets, and can inject the correct link and meta tags into your HTML layout automatically. The CLI is available for Pro subscribers.
