What size should a logo be inside a QR code?

Upload a square (1:1) logo at 600x600 pixels minimum, ideally 1000x1000, as a PNG with a transparent background. The shape matters more than the pixel count: because aspect ratio is preserved, a wide wordmark is scaled down to fit by its width and appears far smaller than a square mark at the identical setting.

Why does my logo look small in my QR code?

Almost always because the logo is wide rather than square. The logo sits in a square space and is never stretched, so a 4:1 wordmark fits by width and leaves empty space above and below. Switching to a square icon version of the same mark typically doubles how large it appears, with no effect on scanning.

Does adding a logo stop a QR code from scanning?

Not at a sensible size. QR codes use error correction that reconstructs data hidden behind a logo, and NexaLink uses Level H, the strongest available. The limit is smaller than most guides suggest, and it depends on the length of the encoded web address: a short custom domain produces a smaller, denser code with less room to give away than a long default link.

Can I export my contacts from Popl or Blinq before switching?

Yes, but export is a paid feature on both and must be done on desktop. In Popl, go to the dashboard, open Leads, select them and click Export for CSV; this requires Pro+ or Teams. In Blinq, open the dashboard, go to Contacts and click Export contacts; this requires Premium or above. Export before you cancel, because deletion is permanent on both platforms and neither offers an export step at the point of deletion.

Does deleting a Popl account cancel the subscription?

No. Deleting a Popl account and cancelling a Popl subscription are separate actions, and billing continues after deletion unless the subscription is cancelled where it was purchased. Deleting also deactivates any QR codes already printed.

Your Logo in Your QR Code

How the logo works, exactly what to upload, and how to bring your details across if you are moving from Popl, Blinq or HiHello.

If you have used Popl before, the short version: NexaLink puts your logo in your QR code automatically and takes it from the card itself — so if you run more than one brand, each card carries its own mark with nothing extra to set up.

How It Works

Your QR code takes its logo from the card, not from your account. That matters if you run more than one business: an estate agency and a lending brand on one account get one mark each, automatically. There is no separate “QR logo” setting to keep in sync and no need to choose one brand over another.

Logo source	The logo on that card (falls back to the card’s photo)
Downloaded file	1024 × 1024 px PNG — print ready
Error correction	Level H, the strongest — the code still scans with the middle covered
No logo yet?	You get a clean, unbranded code. Nothing breaks

To see it: open your card in the app and tap QR. The preview shows the exact code your customers will scan, with the web address printed underneath so you can check it before you print anything.

What to Upload

Shape	Square (1:1) — matters more than everything else here
Size	600 × 600 px minimum · 1000 × 1000 ideal
Format	PNG with a transparent background
Accepted files	JPG, PNG or WEBP — SVG is not accepted
Size limit	5 MB
Design	Bold shapes, strong contrast. Avoid thin or delicate lines
Padding	None — don’t add your own white border, we add the spacing

Coming from Popl? The logo you already made for your PopCode is 540 × 540 and square, which works here as-is. Reuse it and skip this section.

Why a Transparent Background Matters

Your logo sits on a white rounded plate. A logo saved with its own white rectangle behind it shows that rectangle’s hard corners inside the rounded plate. A transparent PNG sits cleanly on it.

Why Square Matters Most

This is the most common reason a logo looks too small. Your logo sits in a square space, and we never stretch or squash it. So a wide logo is scaled down until its width fits, and ends up short, small, and floating in empty space.

A 4:1 wordmark placed in a 225-pixel square box renders about 225 × 56 — roughly a quarter of the area a square mark occupies at the identical setting.

If your logo looks too small, check its shape before anything else. Most companies have a square icon version alongside the wide name-of-the-company version. Switching to the square one typically doubles how large it appears, instantly, with no effect on scanning.

HiHello gives the same advice from the other direction, telling users to avoid text-based logos because of the size of the logo field. It is the same effect.

Can the Logo Be Bigger?

Yes, within limits — and the limits are smaller than most guides claim. The logo covers part of the code and error correction reconstructs what is hidden, but that budget runs out sooner on short web addresses.

A shorter address makes a smaller, denser QR code, and a smaller code has less room to give away. If you use a custom domain such as card.yourcompany.com, your code is one of the smaller ones, so it is the most sensitive to an oversized logo.

We tested this by generating codes at every size and machine-reading them back — the full method and results are in How big can a logo be in a QR code?. Our setting is chosen so every customer’s code scans reliably, including those on custom domains, rather than tuned to the most forgiving case.

Before You Print Anything

A QR code that doesn’t scan fails silently, after it is printed. Five minutes here saves a reprint.

Check the address. Tap QR and read the web address under the code — that is exactly what a scan opens.
Download the PNG, don’t screenshot. The download is 1024 × 1024 and print ready; a screenshot is your screen’s resolution and prints soft.
Print one test copy at final size before the full run.
Scan it with two phones — one iPhone, one Android — from about 30 cm, at an angle, in normal indoor light.
Never print smaller than 2 × 2 cm (about 0.8 in). Below that, phone cameras struggle no matter what.
Scanning from further away? Use the 10:1 rule — about 1 cm of code per 10 cm of distance, so a code read from 3 m needs to be roughly 30 cm. Then add 20–30% for poor light and awkward angles.
Leave white space around it. Don’t crop tight to the edge, and don’t place it on a busy photo.

Moving from Popl, Blinq or HiHello

Do these in order. The order matters, because two of these doors lock behind you.

Export your contacts before you cancel or delete anything. On all three platforms export is a paid feature, and deletion is permanent with no export step offered at that point. Cancel first and you can lose the ability to take your own contacts with you.

Step 1 — Export Your Contacts

Platform	Where	Requires
Popl	Dashboard → Leads → select → Export (top right) → CSV	Pro+ or Teams. Free and Pro cannot export
Blinq	Dashboard → Contacts → Export contacts (top right) → CSV	Premium and above. Not on Free
HiHello	Export contacts to CSV or your CRM	Paid tiers

All three are desktop-only — the export button does not exist in the phone apps. Do this part on a computer.

Step 2 — Save Your Images

Download your profile photo, company logo and cover image from your old card before you lose access. Your existing square logo will usually work here unchanged.

Step 3 — Rebuild Your Card

None of the three platforms let you export your own card content, only your captured contacts. Your name, title, company, links and bio have to be re-entered. It is a five-minute job per card, and it is the same on any platform you move to.

Step 4 — Only Now, Cancel

Deleting your Popl account does not cancel your Popl subscription. They are separate actions — delete the account and the billing quietly continues. Cancel the subscription where you bought it (App Store, Play Store or their dashboard), then delete.

Deleting also deactivates your old QR codes. Anything already printed with a Popl or Blinq code stops working the moment the account goes. Keep the old account alive until your new codes are printed and in circulation.
