QR Code Generator

1. Open the Camera app.
2. Hold the phone so the QR code is inside the frame.
3. Tap the banner that appears at the top of the screen. It opens the link, joins the Wi-Fi or adds the contact.
4. If nothing appears, open Settings, then Camera, and turn on Scan QR Codes.

1. Open the Camera app. Most Android phones read QR codes straight away.
2. Point the camera at the code and wait for the pop-up.
3. Tap the pop-up to open the link, join the Wi-Fi or save the contact.
4. If nothing happens, turn on Scan QR codes in the camera settings, or open Google Lens from the Google app.

1. As a rule of thumb, keep a code at least 2 x 2 cm (about 0.8 inch) for scanning from hand distance.
2. The scanning distance is roughly 10 times the width of the code. A code 10 cm wide scans from about 1 metre.
3. Download the PDF or SVG for posters and large prints. They stay sharp at any size. Use the PNG at 300 DPI for small prints.
4. Leave an empty border around the code. The tool adds one, so do not crop it away.

1. Open Size and print. Set the printed width, for example 5 cm, and choose 300 DPI.
2. Download the print-ready PDF. It holds the code as vector shapes, so the printer can scale it without losing sharpness.
3. If the shop prints in CMYK, choose CMYK under PDF colors. Pure black stays 100 percent black ink. Other colors are a simple conversion, so ask for a proof of brand colors.
4. If the shop wants an image, download the PNG with By print size selected. It carries its DPI, so Word and InDesign place it at the right size.
5. Do not crop or stretch the code. Check a proof with two different phones before the full run.

1. Use the Contact type for badges, with the name, role and company. Use the Event type to add a session to the visitor calendar.
2. On a slide or poster, make the code large. The people at the back of the room need it at least a fifth of the slide height.
3. Add a frame with a short label, such as SCAN TO JOIN, so people know what to do.
4. Need one code per attendee, table or product? Use Make many QR codes at once and download a ZIP.

1. Use a dark code on a light background. Light codes on dark backgrounds fail on many scanner apps.
2. Keep the text short. A shorter link makes a simpler code that is easier to scan.
3. Do not stretch, squash or crop the code, and keep strong contrast between its two colors.
4. If you add a logo, keep it small. The tool switches to the highest error correction for you.
5. Plain squares scan best. If you choose dots, bars or other styles, test the printed copy with two different phones before you print many.

Yes. You can generate as many QR codes as you like without paying, without an account and without a watermark. The codes you download are yours to use for personal or business purposes.

Yes. QR code generator, maker, creator, builder and designer all describe a tool that turns a link, text or contact details into a QR code image. Some people write it as code QR generator or generator QR code. This free tool does all of it: it generates the code, lets you design it with templates, colors, shapes, a frame and a logo, and exports it for screen or print.

No. These are static QR codes, so your link or text is stored inside the code itself. There is no server in between that can be switched off, and no plan that can run out. The code works for as long as the page or information it points to exists.

No. The code is made in your browser, so your link, Wi-Fi password or contact details are never sent to FileXL. Nothing is saved, and nothing is tracked about what you type.

A static code holds your data directly, so it cannot be edited and it never expires. A dynamic code holds a short link to a company server that redirects to your page. That lets the company change the destination and count scans, but the code stops working if the service stops. This tool makes static codes.

No. A static code cannot be changed, because the link is part of the picture. If the link changes, make a new code. If you need a destination that can change, point the code to a page you control, such as a short link on your own website, and update that page instead.

Open the Wi-Fi tab, type the network name and password, and choose the security type. Most home routers use WPA or WPA2 (choose WPA for WPA3 too). Save the code and print it. Guests open the phone camera, scan it and tap to join. Your password stays in your browser.

Open the WhatsApp tab, enter your number with the country code and no plus sign or zeros, for example 923001234567, and add a first message if you want one. The code opens a chat with you when it is scanned.

Student and Workshop use bright gradients with a label such as SCAN ME or SCAN TO REGISTER, which suits posters and handouts. Professional is dark navy with a CONNECT label for cards and CVs. Conference adds a SCAN TO JOIN label above the code for badges and slides. Print shop is plain black, the most reliable choice for print. Every template can be changed afterwards.

Open Size and print, set the printed width, and download the print-ready PDF. It holds the code as vector shapes, so your printer can scale it without losing sharpness. Choose CMYK if the shop asks for it. Pure black stays 100 percent black ink. You can also download the SVG, or a PNG that carries its DPI.

Use the PDF or SVG when you can, because they have no fixed resolution. If you need a PNG, choose By print size, set the width and 300 DPI under Size and print. The file then has the right number of pixels and carries its print size. For a poster read from 2 metres away, make the code about 20 cm wide.

Yes. Open Make many QR codes at once, paste one line per code, such as name | link, choose PNG, SVG or PDF, and download a ZIP. It uses the design you chose. You can make up to 200 codes at a time, and a list.csv in the ZIP shows what each file holds. It can also make contact cards for badges.

Choose the Event type, type the name, the start time and the place, and add the end time or tick All-day. When someone scans the code, their phone offers to add the event to its calendar. Times are used as local time on the scanning phone, so it suits events held in one place.

Choose the PDF or SVG for printing, because they stay sharp at any size, from a business card to a billboard. Choose PNG for websites, documents and chat apps. Choose JPG only if a form asks for it, because JPG has no transparency and can blur sharp edges.

At least 2 x 2 cm (about 0.8 inch) for a code scanned from hand distance. A common rule is that the scanning distance is about 10 times the width of the code, so a code on a poster that people read from 2 metres away should be about 20 cm wide.

The usual causes are low contrast between the two colors, a light code on a dark background, a code that is too small, a logo that is too large, a missing empty border around the code, a fancy shape that your phone reads badly, or too much text packed into it. Fix those and test again. The preview warns you about the common ones.

Yes. Open Logo and upload an image, or pick one of the built-in icons. The tool switches to the highest error correction, which lets a scanner rebuild the small area the logo covers. Keep the logo small and test the code with your phone before you print it.

Yes. Under Colors you can use a gradient and give the three corner squares their own colors. Under Shapes you can choose rounded, dots, classy, pixels or bars, and four corner styles. Under Frame you can add a border or a label such as SCAN ME. Dark colors on a light background scan best, so test the code with your phone.

A QR code carries extra data so it can still be read when part of it is dirty, damaged or covered. There are four levels: L recovers about 7 percent, M about 15 percent, Q about 25 percent and H about 30 percent. Higher levels make a denser code. Medium is a good everyday choice.

The largest QR code can hold up to about 2,950 characters of ordinary text at the lowest error correction. In practice, shorter is better: a short link makes a simple code that scans fast, even from a distance.

Yes. There is no watermark and no attribution is needed for the codes. You can use them on packaging, menus, cards, posters, badges and adverts. Always test the printed result before a large print run.
