QR code

QRcode software is a type of tool focused on generating and parsing QR codes. It can convert text, URL, contact information and other data into scannable QR code images, and supports custom appearance and batch generation. It is widely used in commercial promotion, payment systems, information encryption and other fields.

Software features

Highly customizable and artistically designed

Color and size adjustment: Supports customization of foreground and background colors, such as generating a QR code with a yellow code on a blue background; controlling the size of the pixel block through the box_size parameter to ensure that the QR code is clear and readable.

Embedding logo and dynamic effects: Use the Pillow library to synthesize the logo into the QR code center to enhance brand recognition; combine it with timestamp technology to generate dynamic QR codes, which is suitable for temporary ticketing systems.

Artistic style: Use the StyledPilImage library to achieve effects such as circular modules and gradient colors to enhance visual appeal.

Cross-platform and multi-language support

Programming language compatibility: The Python library supports versions 3.6 and above, the JavaScript library is compatible with mainstream browsers, and the CAD plug-in is compatible with development environments such as Borland C++Builder and Visual C++.

Mobile optimization: The Android application "QR Code" supports multiple encoding methods such as text, URL, and business cards, and the scanning engine is efficient and stable.

Batch generation and high efficiency

Data import and export: Supports batch import of data in Excel, CSV and other formats, and quickly generates a large number of QR codes, suitable for corporate marketing, logistics management and other scenarios.

API interface integration: Provides development interfaces to facilitate seamless integration with other systems (such as payment platforms, CRM systems).

Software function

Basic functions

Data encoding: Convert text, URLs, contact information, etc. into QR code images.

Image output: supports PNG, SVG, EPS and other formats, adapting to different application scenarios (such as printing, digital display).

Scanning analysis: Built-in efficient scanning engine to quickly identify QR code content.

Advanced features

Error correction: Provides four levels of error correction capabilities: L (low), M (medium), Q (quarter), and H (high) to ensure that the QR code can still be read even if it is partially damaged.

Security encryption: Use advanced encryption technology to protect data security during the QR code generation and scanning process.

Multi-code type support: In addition to QR codes, some software (such as Barcode Generator) also supports EAN, UPC, Code 39 and other barcode types.

Featured tools

CAD integration: Draw QR codes in CAD software for information extraction from engineering drawings (such as project number, designer name).

Version identification: Use the QR code to verify the consistency between paper drawings and electronic drawings.

Frequently asked questions and solutions

Rendering issues

The QR code display is incomplete or blurry:

Reason: Improper size setting or CSS style conflict.

Solution: Ensure that the width and height of the QR code container are equal to avoid CSS scaling; use the size attribute to explicitly specify the pixel size (such as <qrcode-vue:size="200" />).

Abnormal color:

Reason: There is insufficient contrast between the foreground color and the background color.

Solution: Choose a high-contrast color combination (such as white code on black background) to ensure scannability.
