How It Works — The URL Trick

Every social platform has a public URL format for profiles and actions. A QR code is just a scannable version of a URL — so all you need to do is find the right URL format for the platform, swap in your username or number, and generate a QR code from it.

When someone scans the code, their phone opens that URL — which takes them straight to your profile, starts a WhatsApp chat, or plays your YouTube channel. No app download required, no typing, no searching.

💡 Always test before printing: Point your phone camera at the QR code preview on screen before downloading. Confirm it opens the correct page. A typo in the URL generates a valid-looking but broken QR code.

Platform-by-Platform URL Guide

Find your platform below, copy the URL format, replace the placeholder with your username or number, then paste it into the FlexoTools QR Code Generator.

💬WhatsApp
URL format
https://wa.me/[your-number]

Replace [your-number] with your full number including country code, no spaces or dashes. Example: https://wa.me/919876543210 for an Indian number.

Step-by-Step: Generate Your QR Code

1

Copy the correct URL for your platform

Use the table above. Replace the placeholder (shown in square brackets) with your actual username, handle, or phone number. Double-check for typos — one wrong character breaks the link.

2

Open the QR Code Generator

Go to FlexoTools QR Code Generator. Make sure the QR Code tab is selected (not Barcode).

3

Paste your URL

Paste the full URL into the Text or URL input box. The QR code preview on the right updates instantly as you type.

4

Customise size and colors (optional)

Use the Size slider to increase the resolution for print use — 300px or higher is recommended for anything that will be printed. Use the Foreground and Background color pickers if you want to match your brand colors. Keep strong contrast between the two for reliable scanning.

5

Test with your phone before downloading

Point your phone camera at the preview on screen. Confirm it opens the correct profile or chat. Only download once you have verified it works.

6

Download or Share

Click Download to save the image, or Share to send it directly via your device's share sheet. The downloaded file is a high-resolution image ready for print or digital use.
