How do I create a QR code?
Pick what the code should hold, then fill in its fields. For a link, paste the full address. For WiFi, enter the network name, the password and the security type, and turn on Hidden network if the name is not broadcast. For WhatsApp, a phone call or a text message, enter an Indonesian number after +62. For an email, add the address and, if you like, a subject and a message. For a contact, fill in the name, phone, email, company, job title and website you want on the card. The code appears as you type, so you can see it change and fix a typo before saving anything.
Then make it yours in the Design tabs. Style sets the shape of the dots and of the three corner squares. Color sets a solid color or a gradient and the background, which can also be transparent. Logo adds your own image in the middle. Frame puts the code in a label or badge with a short caption. Size & quality sets the image size, the error correction and the quiet zone. When it looks right, choose PNG, SVG or JPG and download it, or copy the image straight into a chat or a document.
Tip: Test the code on two different phones before printing. A quick scan check catches a mistyped link or a color that is too light while it is still free to fix.
Which type of QR code should I choose?
- Link. Sends people to a web page, a form, a map location, a menu or a video. The most common choice by far.
- Text. Shows plain words when scanned: an address, a serial number, a coupon code or a note. No internet is needed to read it.
- WiFi. Joins a network on most modern phones. Handy for guests, cafes and holiday rentals.
- WhatsApp. Opens a chat with your number, with an optional ready-written first message. Popular on shop counters and flyers.
- Email, Phone and SMS. Open a new email, the dialer or a new text message, already filled in.
- Contact. Saves a contact card (vCard) with your name, number, email, company and website in one scan.
If you are unsure, a link is the safest choice, because the page it opens can change later even though the printed code cannot.
How do I keep a styled QR code easy to scan?
Contrast matters most. Keep a dark code on a light background: the studio measures the contrast and warns below 4 to 1, or when the code is lighter than its background. With a gradient, the lighter of the two colors is the one that counts. A logo covers part of the pattern, so the studio switches to High error correction while one is added and warns when the logo is bigger than 25% of the code. Leave Clear space on so no dots sit half hidden behind the logo.
Keep the quiet zone, the empty border around the code, at 2 modules or more, and do not stretch the image so it is no longer square. For print, the SVG is the best choice because you can enlarge it without blur; for a large poster, 2048 pixels is the biggest PNG or JPG. Note one important thing: this tool does not create payment codes. It cannot make a QRIS, bank or e-wallet payment QR, which has to come from your payment provider.
Is it safe to make a QR code online?
Yes. The page is online, but the code is generated by your own browser. What you type, whether a private link, a WiFi password or a phone number, and the logo you add are turned into the image on your device and are never sent to a server. There is no account, and nothing about the code is stored for later.
You can confirm it by watching your browser’s network tab while you type: no content is sent out. Because the code is static, there is no hidden redirect or tracking link inside it, so nobody counts or follows the people who scan it. Anyone scanning it sees exactly what you entered. Just remember a WiFi code contains the password in readable form, so share it only where you would share the password.
