Pix2Text (P2T)
中文 | English
Pix2Text (P2T) aims to be a free and open-source Python alternative to Mathpix, and it can already accomplish Mathpix's core functionality. Pix2Text (P2T) can recognize layouts, tables, images, text, mathematical formulas, and integrate all of these contents into Markdown format. P2T can also convert an entire PDF file (which can contain scanned images or any other format) into Markdown format.
Pix2Text (P2T) integrates the following models:
- Layout Analysis Model: breezedeus/pix2text-layout-docyolo (Mirror).
- Table Recognition Model: breezedeus/pix2text-table-rec (Mirror).
- Text Recognition Engine: Supports 80+ languages such as English, Simplified Chinese, Traditional Chinese, Vietnamese, etc. For English and Simplified Chinese recognition, it uses the open-source OCR tool CnOCR, while for other languages, it uses the open-source OCR tool EasyOCR.
- Mathematical Formula Detection Model (MFD): breezedeus/pix2text-mfd-1.5 (Mirror). Implemented based on CnSTD.
- Mathematical Formula Recognition Model (MFR): breezedeus/pix2text-mfr-1.5 (Mirror).
Several models are contributed by other open-source authors, and their contributions are highly appreciated.
For detailed explanations, please refer to the Models.
As a Python3 toolkit, P2T may not be very user-friendly for those who are not familiar with Python. Therefore, we also provide a free-to-use P2T Online Web, where you can directly upload images and get P2T parsing results. The web version uses the latest models, resulting in better performance compared to the open-source models.

Online Service
Everyone can use the P2T Online Service for free, with a daily limit of 10,000 characters per account, which should be sufficient for normal use. Please refrain from bulk API calls, as machine resources are limited, and this could prevent others from accessing the service.
Due to hardware constraints, the Online Service currently only supports Simplified Chinese and English languages. To try the models in other languages, please use the following Online Demo.
Online Demo 🤗
You can also try the Online Demo (Mirror) to see the performance of P2T in various languages. However, the online demo operates on lower hardware specifications and may be slower. For Simplified Chinese or English images, it is recommended to use the P2T Online Service.
Install
Well, one line of command is enough if it goes well.
pip install pix2text
If you need to recognize languages other than English and Simplified Chinese, please use the following command to install additional packages:
pip install pix2text[multilingual]
If the installation is slow, you can specify a domestic installation source, such as using the Aliyun source:
pip install pix2text -i https://mirrors.aliyun.com/pypi/simple
If it is your first time to use OpenCV, then probably the installation will not be very easy. Bless.
Pix2Text mainly depends on CnSTD>=1.2.1, CnOCR>=2.2.2.1, and transformers>=4.37.0. If you encounter problems with the installation, you can also refer to their installation instruction documentations.
Warning
If you have never installed the
PyTorch,OpenCVpython packages before, you may encounter a lot of problems during the first installation, but they are usually common problems that can be solved by Baidu/Google.
For more instructions, please refer to Install .
Usage

HTTP Service
To start an HTTP service for receiving images (currently does not support PDF) and returning recognition results, use the command p2t serve.
p2t serve -l en,ch_sim -H 0.0.0.0 -p 8503
Afterwards, you can call the service using curl:
curl -X POST \
-F "file_type=page" \
-F "resized_shape=768" \
-F "embed_sep= $,$ " \
-F "isolated_sep=$$\n, \n$$" \
-F "image=@docs/examples/page2.png;type=image/jpeg" \
http://0.0.0.0:8503/pix2text
For more information, refer to Command/Starting the Service.
MacOS Desktop Application
Please refer to Pix2Text-Mac for installing the Pix2Text Desktop App for MacOS.
