Free business card tools, no signup, no watermark.
Small things that do one job completely and then leave you alone. Nothing is stored, nothing expires, and none of it asks for an email address.
Small tools that do one thing and then get out of the way. No signup, no email address and no watermark. Nothing you type is stored, and the output is yours to use commercially without attribution. Only the follow-up message generator sends your words to another company: Google’s Gemini API, which writes the drafts.
Eleven so far, all genuinely free.
More when somebody asks for one. We would rather build the thing you keep doing by hand than guess.
vCard QR code generator
A QR code containing your actual contact details rather than a link, so it saves you to a phone with no page to load and no signal needed. Downloads as an SVG that prints sharp at any size.
Best for: Printing on a card, a van, a name badge or a shop window.
Open the tool → EmailEmail signature generator
A signature that renders identically in Gmail, Outlook and Apple Mail: three layouts, your colour, built as a table with inline styles and no images by default, so it never shows as a broken-image icon to somebody blocking remote content. With install guides for each mail app.
Best for: Anyone whose signature currently collapses in Outlook.
Open the tool → Following upFollow-up message generator
Type who you met, where, and what you talked about, and get three drafts: an email, a LinkedIn message and a text, each ready to copy. Nothing is sent from the page, and what you type is not stored.
Best for: The evening after an event, with three people to write to and no words yet.
Open the tool → Your websiteSave my contact button
A button for your own website that opens your card, so a visitor can save you to their contacts in one tap. One plain link, no script.
Best for: Putting a one-tap “save my contact” on your own site, portfolio or link page.
Open the tool → Zoom & TeamsVideo call background
Your real card, as a Zoom or Teams background, with your QR code. Everyone on the call can save you without asking you to spell your email.
Best for: Sales calls, consultations and any video meeting where you want people to leave with your card.
Open the tool → Apple Wallet.pkpass viewer
Drop in any Apple Wallet pass and see its fields, its images and anything that breaks Apple’s rules for its style: too many fields, a strip at the wrong size, text Wallet will truncate. Opened in your browser; the file is never uploaded.
Best for: Checking a pass before you send it, or reading one on a machine with no Wallet.
Open the tool → QR codesLinkedIn QR code generator
Paste your profile address and download a code that opens it, as an SVG for print or a PNG for a slide. Works on a computer, where LinkedIn’s own code does not exist, and works out how small it can print.
Best for: Business cards, resumes, slides and name badges.
Open the tool → Contacts.vcf file viewer
Drop in any vCard file and see every contact in it, with photos, before you import a thing. Reads 2.1, 3.0 and 4.0, flags what a phone will trip on, and exports to CSV. Opened in your browser; never uploaded.
Best for: Checking a contact file someone sent, or one your CRM exported.
Open the tool → ContactsvCard generator
Type your details, add a photo, and download a .vcf file any phone can save, written in the same vCard 3.0 Cardr’s own Save sends. The photo is resized in your browser and never uploaded.
Best for: Sending your contact by email or message.
Open the tool → CostsBusiness card cost calculator
What paper cards cost you or your team in a year, from a dated printer price list or your own, against a free digital card and Cardr’s real prices. Every assumption is a box you can change.
Best for: Making the case for a team, with numbers you can defend.
Open the tool → QR codesQR code size checker
Pick or paste what the code holds, choose the card, and get the smallest safe print size from the code’s real grid, GS1’s published module size and the ISO quiet zone. No rule of thumb.
Best for: Before you send a card with a QR code to the printer.
Open the tool →Each one hits the same wall at the end.
A vCard QR code has your details baked into the pattern, so it works offline forever and can never be corrected. An email signature is pasted into a client, so it is a snapshot that goes stale the day your number changes. Both are genuinely useful and both have the same flaw, which is that they capture your details at a moment rather than pointing at them. That is the problem the paid product solves, and showing it to you is more honest than describing it.

The free tools.
Are these tools really free?
Yes. No signup, no email address, no watermark and no attribution required. You can use the output commercially and for a whole team. There is no trial to expire because there is nothing running. The one limit is on the follow-up message generator’s AI drafts, 10 sets a day for each internet connection; after that it gives templates filled in from what you typed.
Do you store what I type?
No. The QR codes, the signature, the vCard file, the cost and size figures, the contact button and the call background are generated from the query string on the page you are looking at, and nothing is written to a database. The .vcf and .pkpass viewers open your file inside the browser tab and never upload it. Those values do appear in the URL so that a result can be bookmarked or shared, so treat that link the way you would treat the details in it. The follow-up message generator is the exception to both: what you type there is sent to Google’s Gemini API to write the drafts, never appears in a URL, and is not stored by Cardr. The privacy notice has the detail.
Why give these away?
Because they are a better argument than an advert is. Each one solves a small problem completely, and each one runs into the same wall at the end: what you generate is a snapshot, and snapshots go stale the day your details change. That is the problem the paid product exists for, and you can see it for yourself rather than be told about it.
Can I request a tool?
Yes, and we would rather build one somebody has actually asked for. Email support@cardr.co with the thing you keep doing by hand.
The card behind one code.
- Saves to their phone
- Edit it any time
- Free, no card details
The card itself is free too.
Same deal as the tools: no card details, no expiry, and nothing for the other person to install.
