KoloQR is a free, browser-based QR code generator that lets you create fully customized codes for URLs, Wi-Fi, text, email, phone, and social media — with no signup, no watermark, and unlimited downloads.
What is KoloQR?
KoloQR is an open-source web application that runs entirely in your browser and generates QR codes locally, so no content is sent to a server. You choose a content type (URL, text, email, phone, Wi-Fi, or a social profile such as Instagram, X, TikTok, WhatsApp, or YouTube), customize the design with shapes, colors, frames, and an optional logo, then export the finished code as PNG, SVG, PDF, or EPS.
Key Features
- Custom module shapes — Choose between square, rounded, circle, triangle, and hexagon QR code modules.
- Design controls — Set colors for pattern, eyes, frame, accent, center, and text using hex, RGB, or HSL values; add top and bottom text around the code.
- Logo upload — Place your own logo in the center of the code; supports SVG, PNG, and JPG files up to 2 MB, with error correction keeping the code scannable.
- Frames and presets — Pick from dozens of included frame designs grouped by style (custom, circular, hexagonal, triangular) or use ready-made preset texts like "SCAN ME" or "VIEW MENU".
- Export formats — Download as PNG for web or SVG, PDF, and EPS for print; SVG scales to any size without loss.
- Copy to Figma — After generating, copy the QR code directly into a Figma design with a single click.
- Privacy first — All codes are generated locally in the browser; your content is never uploaded to a server.
- Open source — The tool is public and transparent about how it works.
Who is it for?
KoloQR is built for designers, marketers, and business owners who need branded QR codes that scan reliably. Restaurants can create digital menu codes for tables, event organizers can make codes for tickets and check-in, and freelancers can add a scannable link to business cards. It also suits product packaging (linking to manuals or reviews) and hotels (Wi-Fi or room service cards).
What can you do with KoloQR?
- Restaurants: Generate QR codes for digital menus, online ordering, reservations, and reviews, downloaded as high-res SVG for print on table cards.
- Event organizers: Create codes for event schedules, ticket check-in, venue maps, and sponsor promotions with custom colors and logos.
- Businesses: Print custom QR codes on business cards, company profiles, portfolios, and contact information sheets.
- Product packaging: Add codes that point to user manuals, authentication pages, reviews, or promotions, with a logo in the center.
How does KoloQR work?
Using KoloQR takes three steps. First, pick the content type from the options (URL, Wi-Fi, phone, email, social, or text) and enter the destination. Next, customize the code's shape, color, eyes, frame, and add a logo if wanted. Finally, download the finished QR code as PNG, SVG, PDF, or EPS, or copy it straight to Figma.
