QR Code Generator:
Create scannable codes instantly
Generate QR codes for URLs, text, phone numbers, emails, and Wi-Fi. Fully customizable size, colors, and error correction. No watermarks, no signup — download PNG in seconds.
Medium balances scan reliability and data density.
What this tool cannot do
- Dynamic QR codes: These QR codes are static. The data cannot be changed after creation. For editable or trackable codes, use a paid service like QR Tiger or Bitly.
- Logo embedding: Adding a logo in the center requires advanced processing. Use QR Tiger, Beaconstac, or Adobe Express for branded codes.
- Scan analytics: There is no server involved, so scan counts, locations, or device data cannot be tracked.
- Low contrast colors: Pastel-on-pastel or light-on-light color combinations may not scan reliably. Stick to high-contrast pairs.
How it works
Choose data type
Select what you want to encode — a URL, text, phone number, email, SMS, or Wi-Fi credentials. Each type has its own input fields.
Enter your data
Fill in the details. For URLs, include the full https:// address. The QR code preview updates instantly as you type.

Popular use cases
How people and businesses use QR codes
Business cards
Link directly to your LinkedIn profile, portfolio, or contact page so people can connect without typing a long URL.

Frequently asked questions
What is the Best Answer Hub QR Code Generator?
The Best Answer Hub QR Code Generator is a free browser-based tool that creates scannable QR codes from URLs, text, phone numbers, email addresses, and Wi-Fi credentials. Everything runs locally in your browser — no data is sent to any server. You can customize the size, colors, and error correction level, then download the QR code as a PNG image.
Is the QR Code Generator free to use?
Yes, the generator is completely free with no usage limits, no watermarks, and no signup required. You can create as many QR codes as you want, at any size, with full color customization. Unlike many competitors, we do not limit the number of codes or force you to create an account.
What types of data can I encode in a QR code?
You can encode URLs, plain text, phone numbers, SMS messages, email addresses with subject and body, and Wi-Fi network credentials. Simply select the data type from the dropdown, fill in the fields, and the QR code updates instantly. For URLs, always include the full address starting with https:// for best compatibility.
What is the difference between static and dynamic QR codes?
Static QR codes encode data directly into the pattern itself. Once created, the data cannot be changed. Dynamic QR codes store a short redirect URL that points to your actual content, allowing you to change the destination later. This tool creates static QR codes only. For dynamic codes, you need a paid service like Bitly, QR Tiger, or Flowcode that provides redirect hosting and analytics.
What QR code size should I use?
For digital use on websites and social media, 300 to 500 pixels is ideal. For print materials like business cards, use at least 500 pixels to ensure clean edges. For posters and signage, 800 to 1000 pixels works best. The general rule is that the QR code should be at least 2 x 2 centimeters when printed for reliable scanning from a normal distance.
What is error correction and which level should I choose?
Error correction allows a QR code to still scan even if part of it is damaged, dirty, or covered. Low (L) recovers 7% of data, Medium (M) recovers 15%, Quartile (Q) recovers 25%, and High (H) recovers 30%. For most purposes, Medium (M) is the best balance. Choose High (H) if you plan to add a logo in the center or expect the code to be exposed to wear and tear.
Can I customize the colors of my QR code?
Yes. You can change the foreground color (the dark modules) and the background color. However, for reliable scanning, always maintain strong contrast between the two colors. Black on white works best. Avoid light-on-light combinations like yellow on white or pastel on pastel, as most phone cameras struggle to read them.
Will my QR code work with any phone or scanner?
Yes. The QR codes generated by this tool follow the international ISO 18004 standard, which means they work with any modern smartphone camera app, including iPhone Camera, Google Lens, Samsung Camera, and dedicated QR scanner apps on Android and iOS. Older phones without built-in QR scanning may need a third-party scanner app.
Can I add a logo or image to the center of my QR code?
No, this tool does not support logo embedding. Adding a logo requires advanced image processing to maintain the error correction data. If you need branded QR codes with your logo in the center, use a paid service like QR Tiger, Beaconstac, or Adobe Express. When using such tools, always set error correction to High (H) to compensate for the logo covering part of the pattern.
How long do QR codes last?
Static QR codes last forever because the data is embedded directly in the pattern. There is no server, no subscription, and no expiration date. As long as the printed or digital image remains scannable, the QR code will work. Dynamic QR codes, by contrast, only work as long as the redirect service hosting them remains active and paid.
What is the maximum amount of text a QR code can hold?
A standard QR code can hold up to 4,296 alphanumeric characters, 7,089 numeric characters, or 2,953 bytes of binary data. For URLs, this is rarely a concern since most web addresses are under 100 characters. For plain text, very long passages may require a higher resolution image or may fail to scan reliably. Keep URLs short for best results.
Can I track how many people scan my QR code?
No. This tool creates static QR codes, which means there is no server involved and no way to track scans. If you need scan analytics — such as location, time, device type, or total scans — you need a dynamic QR code service like Bitly, QR Tiger, or Scanova. These services redirect through their servers, allowing them to collect usage data.
Why is my QR code not scanning?
The most common reasons are low contrast between foreground and background colors, a code that is too small or blurry, inverted colors (white on black instead of black on white), or too much data crammed into a small image. To fix it, increase the size, switch to black on white, reduce the amount of text, or increase the error correction level to High.
What is the best free QR code generator?
The best free QR code generator depends on your needs. For simple, no-signup creation with full privacy, browser-based tools like this one are ideal because nothing is uploaded to a server. For dynamic codes with analytics, Bitly and QR Tiger offer free tiers with limited scans. For branded codes with logos, Adobe Express and Canva provide free design tools. For maximum privacy and unlimited static codes, a client-side generator like Best Answer Hub is the best choice.
