PaddleOCR
A free developer toolkit for reading text from images and PDFs, parsing document layouts and producing structured data for search, knowledge bases and automation.

What you can do with it
What this tool is for
PaddleOCR helps developers move from scanned pages and image-based text to machine-readable information. It offers text recognition and broader document parsing, so a project can start with a small OCR task or build a pipeline that preserves layout and tables. It is a software toolkit to integrate, not simply a website where every user receives an identical upload allowance.
The useful choice is the level of structure your application needs. A searchable text archive may need recognized lines and locations; a knowledge base may need reading order and paragraphs; a table workflow needs cells associated with the right row and column. Decide on that output before selecting a model, because readable words alone do not guarantee a usable document conversion.

Key features, practical tasks
Capabilities in practice
- Text detection and recognition: The OCR pipeline locates and reads text. Keep recognition results associated with the original page so low-quality regions can be inspected without repeating an entire manual transcription.
- Multilingual model selection: The ecosystem covers many languages, but individual models differ. Current PP-OCRv6 documentation describes one unified model for 50 languages; do not interpret the wider ecosystem language count as a promise for every checkpoint.
- Document layout parsing: PP-StructureV3 supports structured document conversion, including more detailed coordinates. This is useful when downstream processing needs to distinguish paragraphs, tables and their positions rather than concatenate every visible word.
- Document vision-language models: The PaddleOCR-VL family provides another document parsing route. Compare its output with the structure pipeline on your own documents instead of assuming a single published benchmark selects the best workflow for every collection.
- Python integration: The quick start demonstrates prediction and saving results from Python. Keep inference, validation and downstream storage as separate steps so a failed page can be retried without duplicating already accepted records.
- Command-line processing: Documented commands expose OCR and parsing pipelines for repeatable jobs. Record the package version, model and settings alongside the output when reproducibility matters.
- Structured export: Available JSON and Markdown outputs depend on the selected pipeline. Preserve the richer intermediate result where possible; a flattened text export can discard coordinates or table relationships that later become useful.

A practical first workflow
A practical first workflow
- Define the expected output. Choose text lines, document Markdown or structured JSON. Prepare several representative pages including at least one difficult example, not only a clean demo.
- Install a matching environment. Follow the current quick start for the inference engine and package version. PaddleOCR 3.x documentation should not be mixed indiscriminately with older 2.x examples.
- Run a small local sample. Use the documented Python or command-line pipeline, save the output and any available visualizations, and keep the source page in the same review set.
- Review before scaling. Check reading order, language, punctuation, table boundaries and important values. Save the working configuration and define how uncertain pages will be handled in a larger job.
Example prompt or task: Take a two-column PDF page containing a table. Extract structured data, compare the reading order with the original, and verify every table heading and unit before adding it to a searchable knowledge base.
This is a suggested processing task, not a claim of a built-in conversational prompt interface. The right command and parameters depend on the installed pipeline and release.
Find the right plan for you
Local toolkit free
Explore official plans ↗Free software Compute and external services are separate
The free route is local software. Hosted API quotas and optional language-model costs follow their own service terms.
What is free and what can cost extra
The Apache-2.0 toolkit provides a free local route: you supply the machine and run the supported software and models. There is no required per-page cloud purchase for that route. Processing time, model storage, deployment maintenance and any hardware rental still belong in a real project budget.
Hosted APIs and optional language-model integrations are separate services. An OCR extraction pipeline also does not automatically include unlimited paid model calls for summarization or semantic information extraction.
A few things worth knowing
Frequently asked questions
Is PaddleOCR free?
Its Apache-2.0 local toolkit is free under the license. Compute, storage, optional hosted APIs and external model services are separate.
Is it a no-code document chat app?
It is primarily a developer toolkit with Python and command-line workflows. A team can build an application around it, but the toolkit itself is not a complete hosted document-chat product.
Does every model read every supported language?
No. Language coverage belongs to a particular model or pipeline. Check the selected model and test mixed-language examples before processing a whole collection.
Can it preserve tables?
Document parsing pipelines support table structure, but complex borders, merged cells and poor scans can produce errors. Review the output against the page.
Does OCR confidence prove a value is correct?
No. Confidence is a model signal, not independent verification. Important names, identifiers, dates and numeric values should be checked in the source.
Can I use older PaddleOCR examples?
Only after checking version compatibility. The project warns of interface changes between major versions, so current documentation and old snippets should not be assumed interchangeable.
Do I need a cloud language model?
Basic local OCR does not inherently require a paid cloud model. Additional semantic extraction or chat workflows may introduce other components and their costs.

Four useful starting projects
Four useful starting projects
- Build a searchable scan collection: Process a small set of owned scanned documents, keep page identifiers and review names or unusual terms before indexing the text.
- Prepare knowledge-base documents: Extract readable sections from image-based PDFs and retain links back to source pages. Review reading order before splitting the result into retrieval chunks.
- Collect table data: Parse a representative table and compare headers, merged cells, units and totals with the image. Treat the result as a reviewable extraction rather than an automatically verified spreadsheet.
- Read multilingual image text: Select models matching the actual languages and test signs, labels or screenshots that resemble the expected input, including small fonts and mixed scripts.
Platforms, inputs, outputs and setup
Platforms, inputs, outputs and setup
Installation involves both the inference engine and the appropriate PaddleOCR package options. The quick start describes supported engine choices, but not every model or feature has identical behavior across them. Match the selected pipeline, backend, package version and hardware instead of copying an old installation command into a new environment.
Input support includes document images and PDFs through the documented pipelines. Very large pages, skewed scans, compressed text and complex tables deserve their own sample checks. For unattended processing, give each input a stable identifier and record failures, so a partial run does not silently appear to be a complete archive.
Data, permissions and licensing
Data, permissions and licensing
A local setup can keep document processing under your control, while model downloads and any chosen remote endpoints remain separate network activities. Review where files and results are stored, particularly when adding a hosted service to the pipeline.
The code license does not grant rights to process or redistribute every document. Use appropriate source material, retain the original for verification, and manage extracted text with the same care as the scanned file because it can contain the same sensitive information.
