Use wechat OCR in Snipaste.

Currently only Snipaste PRO supports OCR.

This program is built for Windows x64 with AVX2 CPU. Arm64 and x86 are not supported.

Go to releases to download a pre-build wechat-ocr-snipaste.exe, or compile from source yourself.

1. Make sure WeChat PC is installed.

• Prepare a param called ocrBin, which is full path (including file name) of wxocr.dll or wechatocr.exe. Examples:
  • C:\Users\name\AppData\Roaming\Tencent\WeChat\XPlugin\Plugins\WeChatOCR\7061\extracted\WeChatOCR.exe
  • C:\Users\name\AppData\Roaming\Tencent\xwechat\XPlugin\Plugins\WeChatOcr\8075\extracted\wxocr.dll
• Prepare a param called wechatDir, which is WeChat path (usually with a version in path, typically where mmmojo_64.dll exists). Examples:
  • C:\Program Files\Tencent\WeChat\[3.9.8.25]
  • C:\Program Files\Tencent\Weixin\4.1.5.30
• It is recommended to copy the parent directory of these two paths to another location.

2. Download wcocr.dll, and save it to the same folder as wechat-ocr-snipaste.exe.

• You can get the dll from swigger/wechat-ocr or fanchenggang/wechat-ocr-go.

3. Configure Snipaste:

• Go to Snipaste -> Preferences... -> Output -> Text Recognition
• Set OCR Engine to Tesseract
• Set Executable to the wechat-ocr-snipaste.exe
• Set Options to -ocrBin "..." -wechatDir "..." following step 1.
  • The default paths are ocrBin\wxocr.dll and wechat\wechatDir, where wechat-ocr-snipaste.exe is located.
  • Do not use a backslash \ at the end when enclosing quotation marks ".

This program creates temporary files when running, and delete them when exited normally. That is due to limitations imposed by the upstream class library.

If the configuration does not work, you can try to run cmd and execute the following command to see error logs:

chcp 65001
type "C:\your\image.png" | "C:\your\wechat-ocr-snipaste\wechat-ocr-snipaste.exe" stdin stdout -ocrBin "..." -wechatDir "..."

This project will not exist without them:

• swigger/wechat-ocr
• fanchenggang/wechat-ocr-go
• Coxxs/sp-oneocr
