Getting started

Do I need to sign up to make a QR code?

No. You can create, customize, and download QR codes without an account. Signing up lets you save them to the cloud and access them across devices.

What types of QR codes can I create?

URL, plain text, email, phone, SMS, WiFi, vCard, location, PDF, YouTube, WhatsApp, LinkedIn, and restaurant menu. All types are free.

Dynamic codes

What's a dynamic QR code and why would I use one?

A dynamic QR code points to a short link that you control. You can change the destination URL at any time — the printed QR never needs to change.

Can I change where a dynamic QR code points after I've printed it?

Yes. Go to My QRs, open the code, and edit the destination. Changes take effect within seconds — no reprinting needed.

Can I A/B test two destinations from one QR code?

Yes, on the Business tier. In the My QRs detail view, add an A/B redirect rule that splits scans across 2–4 destination variants by percentage. Each visitor is consistently bucketed into one variant, and you get per-variant scan counts with a statistical-significance read in the analytics view.

Exports

What's the difference between PNG, SVG, and PDF exports?

PNG is a raster image — good for digital use. SVG is vector and scales to any size without pixelating — best for design tools. PDF includes 3mm bleed and a CMYK profile — use it when sending to a printer.

What resolution should I use for print?

Use SVG or PDF for print — they're resolution-independent. If you need PNG, export at 2048px or higher. The minimum physical size for reliable scanning is 1 inch (25mm).

Bulk generation

Can I generate many QR codes at once from a spreadsheet?

Yes, on the Business tier. From My QRs, choose Bulk upload, download the CSV template, fill in a row per code (name and destination required), and upload it. We generate up to 500 codes per batch and group them into a folder named after your file.

How do I export a whole batch?

Open the folder a bulk upload created and export it as a ZIP of individual PNG or SVG files, or as a single print-ready multi-page PDF (one code per page). Bulk generation and batch export are Business-tier features.

Developer API

Does QRBliss have an API?

Yes, on the Business tier. The QRBliss REST API lets you create and manage QR codes, dynamic codes, redirect rules, scan analytics, and assets programmatically — 10,000 requests per month per key. Create API keys in Settings (choose full-access or read-only), authenticate with a Bearer token, and explore the interactive reference at /api/v1/docs.

Custom domains

Can I use my own domain for my QR short links?

Yes — custom domains are a Business plan feature. Once connected, your dynamic QR short links use your own domain (for example go.yourbrand.com/r/abc123) instead of qrbliss.com. You connect and manage your domain in Settings, one domain per account.

How do I connect my custom domain?

In Settings, under Custom domain, enter a domain or subdomain you control — a subdomain like go.yourbrand.com is the easiest to set up. QRBliss then shows you the exact DNS records to add at your registrar; add them and click Verify domain. It has to be a domain you can edit DNS for — you can't verify one you don't own, which is the most common first mistake.

Which DNS records do I add — CNAME or A?

It depends on whether you're using a subdomain or a bare domain. For a subdomain (e.g. go.yourbrand.com), add the CNAME record QRBliss shows you; for a bare apex domain (e.g. yourbrand.com), add the A record instead. Add only one of the two — having both causes a conflict. You'll also add a TXT record (its name starts with _qrbliss-verify) so we can confirm you own the domain. On providers like Cloudflare, enter the Name relative to your domain (e.g. 'go', not the full hostname) and set the record to DNS only (the grey cloud).

My domain won't verify, or it shows "Not Secure" — what should I check?

The usual causes: DNS hasn't propagated yet (allow up to 24 hours); a Cloudflare record is proxied (switch it to DNS only / grey cloud); a CAA record is blocking the certificate (add one allowing Let's Encrypt — 0 issue "letsencrypt.org"); or both a CNAME and an A record are present (keep just one). Fix the record and click Verify domain again — HTTPS is issued automatically a few minutes after a domain verifies.

When do my QR codes start using my domain — and what about codes I already made?

Once your domain shows Active, every new dynamic code you create uses it automatically. Codes you made earlier keep their qrbliss.com link until you switch them over one at a time with the "Use my domain" action on each code. Heads-up: if you later remove the domain, codes already printed with your branded link will stop working — only qrbliss.com links keep resolving.

Can I connect more than one custom domain?

One custom domain per account today. Multiple domains are planned as part of Team Workspaces (one domain per workspace) rather than a stack of domains on a single account. If you need more than one right now, get in touch and we'll talk through your use case.

Accounts & history

What happens to QR codes I make before signing up?

They're saved to your browser's local storage as 'ghost' QRs. They stay there until you sign up or clear your browser data. You can make up to 100 before being prompted to create an account.

How do I claim my QR codes after creating an account?

When you sign up, a one-click modal appears showing all your ghost QRs. Click 'Yes, claim them' and they move to your cloud library instantly — no re-keying needed.

Troubleshooting

My QR code won't scan — what should I check?

Check contrast first — the QR needs at least 3:1 contrast between the dots and background. Make sure there's a quiet zone (clear margin) around all four sides. If you have a logo overlay, increase error correction to H in the Advanced tab.

My logo upload didn't apply — what went wrong?

Supported formats are PNG, JPG, SVG, and WebP up to 5MB. If the file is valid and the logo still doesn't appear, try refreshing and re-uploading. SVG files with embedded scripts are blocked for security reasons.
