QR Scanner Pro: Code Maker

QR Scanner Pro: Code Maker is a simple tool for scanning QR codes and barcodes, creating your own codes, and generating many codes at once from TXT or CSV files.

The app is designed for everyday use, work tasks, labels, links, internal lists, file sharing, and batch code preparation.

✨ Main features

📷 QR and barcode scanner
Use your camera to scan QR codes and barcodes. The app shows the result on a separate screen, where you can open a link, copy the value, share it, save it, or add it to favorites.

🖼 Scan from gallery
You can select an image or screenshot from your device and scan a QR code or barcode from it. This is useful when a code was sent to you in a messenger, saved as a picture, or stored as a screenshot.

📋 Paste from clipboard
If you already copied a link, text, number, or code value, you can paste it directly from the clipboard and process it inside the app.

🧾 Create QR codes
Create QR codes for links, text, and other data. The app shows a preview before saving, so you can check the result first.

🏷 Create barcodes
QR Scanner Pro also supports barcode generation, including Code 128. You can create barcode images and save or share them as PNG files.

📦 Batch code generation
The key feature of the app is batch generation.

You can:

paste a list manually;
upload a TXT file;
upload a CSV file;
choose a code format;
check rows before generation;
detect errors and duplicates;
save generated images to the gallery;
save results as a ZIP archive;
share generated files through the Android share menu.

This is useful when you need to create several codes at once instead of generating each one manually.

✅ Data validation before generation
Before creating a batch, the app checks the input and shows:

total rows;
valid rows;
errors;
duplicates;
first rows for review.

If the selected format has specific requirements, the app shows a clear message. For example, EAN formats require numeric values, while Code 128 supports text and numbers.

💾 Save and share files
Generated codes can be saved as PNG images. Batch results can be saved to the gallery or packed into a ZIP archive. You can also share PNG or ZIP files using the standard Android share menu.

🕘 Local history
Scanned and generated codes are saved in local history on your device. You can search, reopen, favorite, or delete history items when needed.

🎨 Light and dark themes
The app supports light and dark themes. You can choose the theme manually in settings.

🌐 Languages
The app supports English, Russian, and Simplified Chinese. The language can be selected in settings.

🔐 Local-first approach
QR codes, barcodes, history, generated images, and ZIP files are stored on your device. The app does not require an account.

🎁 Ad control option
The app may show ads. In settings, you can watch a rewarded ad to hide banner ads for a limited time.

QR Scanner Pro: Code Maker is made for users who need a QR scanner, barcode scanner, code generator, and batch code creation tool in one clean app.
