🚀 Getting Started

No build step, no dependencies to install – just clone and open.

# Clone the repo
git clone https://github.com/TajkirHossen-14/LinkVerse.git

# Move into the project folder
cd LinkVerse

# Open index.html in your browser

Note: The service worker only registers over http(s), so offline caching activates on a deployed site or local server, not when opening index.html directly from the filesystem.

❓ FAQ

Is LinkVerse free to use?

Yes — every tool on LinkVerse is free, with no sign-up required.

Do the short links expire?

Short links stay active as long as the underlying shortening service keeps them live.

What's the difference between a QR code and a barcode?

QR codes hold more data and scan from any angle; barcodes are the familiar single-direction stripes used for retail and inventory scanning.

Can I customize the QR code with my own colors or logo?

Yes — set your own colors or a linear/radial gradient, choose a frame, pick an error-correction level, and drop a logo into the center. You can save the whole look as a preset or copy a shareable style link.

Which barcode formats are supported?

Code128, EAN-13, EAN-8, UPC-A, Code39, ITF, and Codabar.

Do I need an account?

No account or email is required for any tool.

Can I download what I generate?

Yes — export QR codes and barcodes as PNG or SVG (QR also supports PDF). Batch runs can be downloaded as a single ZIP archive, and your history exports as CSV or JSON.

Can I read an existing QR code?

Yes — upload a QR image in the QR tab and LinkVerse decodes it back to text in your browser. Nothing is uploaded anywhere.

Does LinkVerse work offline?

After your first visit the page and its libraries are cached by a service worker, so the QR and barcode tools keep working offline. Link shortening still needs a connection.

Is my data stored anywhere?

Your history is saved locally in your browser only; LinkVerse doesn't store it on a server.
