Why we built these tools
Working with clients, we keep running into the same small jobs: creating a Google review link, printing a QR code for the reception desk, checking whether an ad headline fits into 30 characters, or tagging a newsletter link so it shows up correctly in Google Analytics. There are tools for all of this, but many are cluttered, ask for an email address or push a paid plan. So we put clean versions in one place.
Your data stays on your device
Most tools run entirely in your browser. When you check an IBAN, build an email signature or generate a QR code, nothing is sent to our server. The only exception is the website checker: our server opens the public address you enter, just like any visitor would, and does not store the result.
Who the tools are for
- Hosts and hospitality: review link and QR code, WhatsApp link for faster guest enquiries.
- Anyone running ads: ad character counter, UTM links for campaign tracking, a website check before you spend money on traffic.
- Buyers and businesses in Croatia: IBAN check and the Croatian OIB (tax number) checker.
Frequently asked questions
Are the tools really free?
Yes. They are free and need no sign-up. The pages are funded by ads and by the fact that some users later hire us for Google Ads.
Do you store what I type?
No. Apart from the website checker, every tool runs in your browser and nothing is sent to our server. The website checker only opens the public address you enter and does not store the result.
Can I suggest a new tool?
Please do. Send your idea via WhatsApp or to marketing@supremio-digital.com. If it is useful to others, we will build it.
