QRelix

Dynamic QR Codes & Real-Time Updates

Never worry about a broken link or outdated information again. QRelix's dynamic QR codes are the heart of the platform. You can update the destination URL, file, or content linked to your QR code at any moment from your dashboard. This means a code printed on a permanent menu, product package, or billboard can be changed in seconds, allowing for agile marketing, error correction, and A/B testing without any reprinting costs or waste.

Advanced Real-Time Analytics Dashboard

Track the performance of every campaign with precision. The QRelix dashboard provides detailed, real-time analytics for every scan. See total scan volume, pinpoint scan locations on a map, identify the device types (iOS, Android) and operating systems used, and analyze the time and date of each access. This data is crucial for measuring campaign ROI, understanding audience behavior, and optimizing your placement and messaging for better engagement.

High-Resolution Customization & Branding

Create QR codes that are an extension of your brand, not an eyesore. The platform offers deep design customization. You can change the colors of the QR code dots and background, add a central logo, and adjust the style to ensure it matches your marketing materials. The finished product exports as a 300 DPI SVG file, a vector format that guarantees perfect, sharp printing at any size on business cards, posters, flyers, or packaging.

Mirrored QR & Password Protection

Two powerful features for control and versatility. The unique Mirrored QR feature allows you to take any existing QR code (even one you didn't create) and "mirror" it through QRelix. This lets you apply your own branding and, most importantly, gain access to the scan analytics for that code. Additionally, you can enable password protection on your codes, restricting access to specific content, offers, or documents to only those with the password, adding a layer of security.

SubtitlesFast

Auto-Transcription

SubtitlesFast offers an impressive auto-transcription feature that supports over 50 languages, allowing users to effortlessly convert spoken content into written subtitles. This feature saves time and effort, enabling content creators to focus on crafting engaging videos rather than manually transcribing their scripts.

Customizable Styles

With over 30 animated styles available, SubtitlesFast provides users with the ability to customize their subtitles to match their brand's aesthetic. This feature is particularly valuable for content creators who want to maintain a consistent look and feel across their videos, ensuring brand recognition and enhancing viewer engagement.

Simple Editor

The intuitive editing interface of SubtitlesFast makes it easy for users to make adjustments to their subtitles. With timeline editing capabilities, users can add text, images, and music seamlessly. This feature eliminates the learning curve often associated with video editing software, enabling creators to get their videos ready for publication quickly.

One-Click Export

SubtitlesFast simplifies the publishing process with its one-click export functionality. Users can burn subtitles directly into their videos for platforms like TikTok, YouTube, and Instagram, ensuring that their content is ready to go without any additional steps. This feature allows for a streamlined workflow, saving creators valuable time.

Use Cases

QRelix

Restaurant Digital Menus & Contactless Ordering

Modernize the dining experience effortlessly. Restaurants can generate QR codes for their digital menus, linking directly to an online menu or ordering system. Placed on tables or posters, these codes enable contactless browsing and ordering. The dynamic feature allows for instant menu updates (daily specials, price changes) without reprinting table tents. Analytics show peak engagement times, helping to optimize staff scheduling.

Event Management & Engagement

Streamline event logistics and boost attendee interaction. Event organizers can use QR codes for quick ticket check-in, linking to digital schedules, speaker bios, feedback surveys, or exclusive post-event content. A single code on promotional materials can be dynamically updated post-event to link to photo galleries or replay videos, extending engagement and measuring overall interest from initial advertisement to post-event follow-up.

Retail Product Storytelling & Inventory

Bridge the gap between the physical shelf and digital information. Retailers can place small QR codes on product packaging or shelf tags. When scanned, these can link to detailed product information, demonstration videos, customer reviews, or complementary items. For inventory, codes can link to real-time stock levels or instruction manuals. The tracking data reveals which products generate the most digital engagement.

Personal Networking with Smart vCards

Leave a lasting, updatable digital impression. Professionals can create a QR code linked to a dynamic vCard (digital business card). When scanned, it instantly saves your contact details to the user's phone. The powerful advantage is that if you change your phone number, job title, or website later, you can update your vCard information in QRelix, and every previously printed QR code will automatically point to the new, correct details.

Frequently Asked Questions

QRelix FAQ

What makes a QR code "dynamic"?

A dynamic QR code is one where the destination content (like a URL) can be changed after the code has been created and printed. With QRelix, the code itself remains the same, but it points to a short, redirecting link that you control. You can log into your dashboard anytime and update where that redirect goes, meaning the physical code never needs to be replaced, saving time and resources.

Is QRelix really free to use?

Yes, QRelix offers a fully-featured free plan to get started. You can sign up without a credit card, create dynamic QR codes, customize them with your branding, and access analytics. This free tier is designed to be powerful enough for most individual and business needs. The platform operates on a freemium model, meaning additional advanced features or higher volume needs may be available in paid tiers.

What file format do I get for printing?

QRelix provides QR codes in 300 DPI SVG (Scalable Vector Graphics) format. This is a print-ready, vector-based file type. Unlike pixel-based formats (like PNG or JPG), an SVG can be scaled to any size--from a tiny business card to a massive billboard--without any loss of quality or sharpness, ensuring your codes always look professional and scan perfectly.

Can I track scans from a QR code I didn't originally create?

Yes, through the unique Mirrored QR feature. If you have a physical QR code (e.g., on a competitor's flyer or a public document) that you want to track or rebrand, you can use QRelix to create a "mirror" of it. This creates a new, dynamic code that redirects to the same target but is now housed in your QRelix dashboard, allowing you to apply your branding and, critically, view all the scan analytics for it.
