QR Code Generator: create custom QR codes directly in your browser
QR codes are everywhere now. From restaurant menus and product packaging to event tickets and login screens, those small black‑and‑white squares make it incredibly easy to jump from the physical world to digital content.
Instead of typing long URLs or contact details, users simply point their phone camera at a QR code and they’re there in seconds.
If you’re sharing links, digital products, business info or any other content, a QR Code Generator is one of the most useful tools you can have. And when your generator runs entirely in the browser, you get all the convenience without worrying about privacy or logins.

Best practices for designing and using QR codes effectively
What is a QR Code Generator?
A QR Code Generator is a tool that converts text into a scannable QR code image. That text can be almost anything, including:
- Website URLs
- Plain text messages
- Email addresses and “mailto:” links
- Phone numbers and “tel:” links
- Wi‑Fi connection strings
- App deep links
- Coupon codes and promo IDs
The generator encodes this data into the square grid pattern that QR readers and phone cameras can understand. You can then:
- Download the QR code as an image (usually PNG)
- Print it on flyers, posters, packaging or business cards
- Embed it in presentations or PDFs
- Share it digitally in emails and social media
The QR Code Generator tool you’re adding to your WordPress site works fully client‑side. All generation happens directly in the user’s browser:
- No data is sent to an external server
The tool responds instantly, even when offline after the page loads
Why use a QR Code Generator?
You could just paste a URL into a social post and call it a day. But QR codes offer some powerful advantages in many situations.
1. Bridge offline and online
QR codes are perfect for connecting physical materials to online experiences:
- Posters and flyers → event registration page
- Product packaging → how‑to videos or manuals
- Business cards → portfolio or LinkedIn profile
- Storefront signs → menu, order page or appointment booking
With a QR Code Generator, you control exactly where those codes send people.
2. Reduce friction and typos
Typing long URLs or complex codes on a phone is slow and error‑prone. A QR code:
- Requires just a quick camera scan
- Eliminates typos and broken links
- Works well for older users or non‑tech audiences
If the destination URL is important (for example, payment pages or forms), a QR code makes sure people land in the right place.
3. Make print materials more powerful
Static printed content can only include so much information. With QR codes, a simple postcard or poster can:
- Link to a full landing page
- Offer downloads or bonus resources
- Lead to a form, survey or newsletter signup
- Point to videos, galleries or interactive content
A QR Code Generator helps you turn every printed piece into a doorway to more value.
4. Share contact details and Wi‑Fi easily
QR codes are also great for personal and internal uses:
- Share your vCard or contact details at events
- Offer quick access to Wi‑Fi in a café or office
- Provide internal links to documentation or dashboards
Instead of explaining a long URL or password, you just show the QR code.
Why use a client-side QR Code Generator?
Many online QR generators send your data to a remote server to generate the image. That may be fine for public URLs, but not ideal for:
- Internal or private links
- Temporary test URLs
- Contact details or other personal information
A client‑side QR Code Generator solves that:
- All generation happens in the browser
- Your input stays on your device
- No data is stored or logged on a backend
- You can use it as often as you like without accounts or limits
It’s the best of both worlds: the convenience of an online tool with the privacy of local software.
Key features of this QR Code Generator tool
The QR Code Generator shortcode you’ll embed in WordPress provides a clean, flexible interface with several important features.
1. Multiple input methods
Users can add QR items in two main ways:
- Manual input
- Type or paste any text or URL into a text area
- Click “Add to list” to create a new QR item
- Type or paste any text or URL into a text area
- Drag‑and‑drop / file upload
- Drag .txt or .csv files onto the upload area
- Or click “Browse files” to select them
- Each non‑empty line in the file becomes a separate QR code data item
- Drag .txt or .csv files onto the upload area
This makes it easy to generate:
- One‑off QR codes for single URLs
- Multiple QR codes in bulk from a list of links or codes
2. Live preview of all QR codes
Every item appears as a card with:
- A QR code preview
- A truncated text preview (so you can see what it contains)
- Original text length and index in the list
Users can:
- Scroll through all QR codes
- Remove any individual card with a small × button
- Regenerate all QR codes after changing size or colors
3. Visual customization options
The tool includes basic visual controls:
- Size slider – adjust the pixel size of each QR code (great for different layouts)
- Foreground color – change the QR dots color (default black)
- Background color – change the QR background (default white)
- Error correction level – choose between L, M, Q and H
- Higher levels offer better readability when the code is partially covered or printed small, at the cost of slightly denser patterns
- Higher levels offer better readability when the code is partially covered or printed small, at the cost of slightly denser patterns
When you adjust these options, the tool re‑renders all QR codes so you immediately see the new style.
4. Download individual QR codes
Each card includes a Download PNG button which:
- Converts the QR canvas to a PNG data URL
- Triggers a download of just that QR code as an image file
Users can then insert the PNG into documents, design tools, or print layouts.
How to use the QR Code Generator (step by step)
Once you add the shortcode to a WordPress page, your visitors can use the QR Code Generator as follows.
Step 1: Open the QR Code Generator page
Navigate to the page where you inserted. You’ll see:
- A heading and short description
- A drag‑and‑drop upload area with a “Browse files” button
- A manual input field for adding QR data
- Global settings (size, colors, error correction)
- A preview grid area where generated QR codes will appear
Step 2: Add QR data manually
To add a single QR code:
- In the “Enter text or URL” field, type or paste your content. Examples:
- https://yourwebsite.com/landing-page
- mailto:hello@example.com
- tel:+1234567890
- Discount code: SPRING25
- https://yourwebsite.com/landing-page
- Click “Add to list”.
- A new card appears in the preview grid with a QR code and text snippet.
You can repeat this step to add as many different QR codes as you like.
Step 3: Add multiple QR codes from a file (optional)
To generate QR codes in batch:
- Prepare a .txt or .csv file on your computer where:
- Each line contains one piece of data (URL, text, code, etc.)
- Blank lines will be ignored
- Each line contains one piece of data (URL, text, code, etc.)
- Drag that file into the upload area, or click “Browse files” and select it.
- The tool reads the file client‑side and creates one QR item per line.
- Each item appears as a card in the preview grid.
You can upload multiple text/CSV files; their content will be appended to the current list.
Step 4: Adjust size, colors and error correction
On the right side, use the controls:
- QR size slider – choose how big each QR code should be (for example 200–400px).
- Foreground color – select the QR code color (dark color recommended).
- Background color – select the background color (usually white or light).
- Error correction level – pick L, M, Q or H:
- L – lowest redundancy, smallest pattern
- H – highest redundancy, better scan reliability
- L – lowest redundancy, smallest pattern
Whenever you adjust these settings, the tool automatically regenerates all QR codes using the new style.
Step 5: Download QR codes
For each card:
- Click “Download PNG”.
- Your browser downloads a .png image file containing that QR code.
- Save it, rename it and use it in your projects (print or digital).
You can generate multiple versions (for different colors or sizes) by adjusting the options and downloading again.
Step 6: Remove or reset
If you need to tidy up:
- Click the × button on any card to remove that QR code from the list.
- Click the “Reset” button to clear all items and start again.
No data is stored – everything is transient in the browser session.
Best practices when creating QR codes
To get the most from your QR Code Generator, keep these tips in mind:
- Test your QR codes
Always scan your QR code with at least one phone camera to make sure it goes to the right place. - Use clear destination pages
If a QR code is for a special promotion or event, send users to a dedicated landing page instead of a generic homepage. - Mind contrast and background
Use a dark foreground color and light background. Avoid placing QR codes on very busy backgrounds when printing. - Give people context
Add a short label near the QR code: “Scan to visit our website”, “Scan to download the app”, etc. - Consider error correction
For small or partially covered codes (e.g., on stickers), choose a higher error correction level like Q or H. - Don’t stretch or distort
Keep QR codes square. Stretching them horizontally or vertically can make them hard to scan.
