How to create a LINE QR Code on AI Two

What a LINE QR code does

You enter the LINE profile, official account, or invite URL, generate a QR image, and download a scan verified PNG for print or screen.

When I tested an official account link, the scan opened the mobile LINE view so staff did not need to spell the ID aloud in a noisy shop.

Credits apply per generation. I lock the URL first, then pick size and color styling if the form offers it.

Stay in QR Studio for Instagram, Facebook, TikTok, and Telegram generators when the destination is another social or messaging profile.

I treat messaging codes like seasonal signage. If the account URL changes, I regenerate and reproof.

Scan verification catches broken patterns before download. I still proof on paper at final size.

In my experience, a short call to action beside the code helps staff explain that the scan opens LINE chat or the official account.

For regional campaigns I date the filename so old stickers are not mixed with a new LINE destination after a rebrand.

I keep a printed proof in the store binder so weekend staff scan the same code guests see on the counter.

When a night market stall runs for one weekend only, I still export at the final print width the vendor quotes instead of stretching a small PNG later.

I write the LINE account name and campaign month on the proof margin so staff can retire the card when the promo ends.

How to run it step by step

Step one: copy the exact LINE profile or official account URL from LINE. Step two: open LINE QR Code in QR Studio. Step three: paste the URL, generate, wait for scan verification, download. Step four: print or embed at the size you need. Step five: scan with two phones before a large print run.

I keep a screenshot of the destination account in the project folder beside the PNG.

Store the file with the account name in the filename notes.

If marketing changes the LINE URL, regenerate. Do not edit modules in a layout app.

When I proofed a table tent, warm bulb glare was the real test, not the monitor preview.

I note print width in millimeters beside the filename for vendor reorders.

If one phone struggles, I enlarge the art ten percent and regenerate.

I add the LINE ID in plain text under the code for guests who prefer typing when the network is slow.

I proof once on a phone with LINE installed and once on a phone that may prompt an install, so staff know what guests will see.

Credits apply per generation, so I lock the destination URL and call to action text before I explore color styling options.

When the booth also promotes Instagram, I keep a separate Instagram QR in the same folder instead of forcing one generic link.

Print and placement tips

Use high contrast modules on a light field for counter cards and window stickers.

Matte stock reduces glare. Glossy cards can mirror shop lights into the camera.

Size for the real viewing distance. Guests often scan from arm length at a register.

Leave a quiet zone free of logos and patterns.

Place the code where thumbs naturally reach on a table tent. Corner placement on folded stock fails in the wild.

Test under the lighting that matches the install location, including warm restaurant bulbs.

Avoid printing over busy photography backgrounds without a white sticker island.

For outdoor night markets, bump module size and quiet zone because phone cameras struggle under mixed string lights.

Older cameras need bigger quiet zones than new flagships, so I size for the weakest phone I expect at the venue.

Mistakes I avoid

Using a temporary invite link that expires after the campaign week.

Skipping the phone proof because the PNG verified on screen.

Printing five hundred stickers before a two phone test.

Saving a low resolution PNG and upscaling in the layout app.

Mixing QR art with heavy dither textures that eat module edges on press.

Pointing the code at a personal chat URL on public signage when the brief needs an official account.

When to use another QR tool

Need Instagram, Facebook, TikTok, or Telegram instead? Open those pages in the social cluster. Need a generic URL? Essential types. Need scan analytics? Dynamic codes in My QR Codes.

The social media cluster guide maps sibling pages. The QR Studio pillar maps everything else.

Business cards that promote several networks sometimes need separate codes per platform instead of one generic link.

If the job is email or SMS contact instead of LINE messaging, open those contact generators in QR Studio rather than forcing this page.

After the download

I attach the verified PNG to the print vendor ticket with quiet zone notes so prepress does not crop modules.

For cafe counters I schedule a lunch-hour scan test after install when foot traffic and lighting match peak service.

If marketing rotates campaigns monthly, I date the filename and retire old stickers so staff do not post outdated LINE destinations.

I keep a screenshot of the live LINE account beside the PNG in the project folder for quick audits when a guest reports a failed scan.

Weekend staff sometimes swap counter creative without telling marketing, so the binder proof is the source of truth for which code is live today.

I store the payload URL in a text file beside the image so future teammates know which LINE destination the sticker opens without opening design files.
