Optical character recognition has moved from plain textual content extraction to doc intelligence. Fashionable techniques should learn scanned and digital PDFs in a single cross, protect format, detect tables, extract key worth pairs, and work with a couple of language. Many groups now additionally need OCR that may feed RAG and agent pipelines immediately. In 2025, 6 techniques cowl most actual workloads:
- Google Cloud Doc AI, Enterprise Doc OCR
- Amazon Textract
- Microsoft Azure AI Doc Intelligence
- ABBYY FineReader Engine and FlexiCapture
- PaddleOCR 3.0
- DeepSeek OCR, Contexts Optical Compression
The purpose of this comparability is to not rank them on a single metric, as a result of they aim completely different constraints. The purpose is to point out which system to make use of for a given doc quantity, deployment mannequin, language set, and downstream AI stack.
Analysis dimensions
We examine on 6 secure dimensions:
- Core OCR high quality on scanned, photographed and digital PDFs.
- Format and construction tables, key worth pairs, choice marks, studying order.
- Language and handwriting protection.
- Deployment mannequin absolutely managed, container, on premises, self hosted.
- Integration with LLM, RAG and IDP instruments.
- Price at scale.
1. Google Cloud Doc AI, Enterprise Doc OCR
Google’s Enterprise Doc OCR takes PDFs and pictures, whether or not scanned or digital, and returns textual content with format, tables, key worth pairs and choice marks. It additionally exposes handwriting recognition in 50 languages and may detect math and font model. This issues for monetary statements, academic varieties and archives. Output is structured JSON that may be despatched to Vertex AI or any RAG system.
Strengths
- Top quality OCR on enterprise paperwork.
- Sturdy format graph and desk detection.
- One pipeline for digital and scanned PDFs, which retains ingestion easy.
- Enterprise grade, with IAM and information residency.
Limits
- It’s a metered Google Cloud service.
- Customized doc varieties nonetheless require configuration.
Use when your information is already on Google Cloud or when you should protect format for a later LLM stage.
Textract gives two API lanes, synchronous for small paperwork and asynchronous for big multipage PDFs. It extracts textual content, tables, varieties, signatures and returns them as blocks with relationships. AnalyzeDocument in 2025 may also reply queries over the web page which simplifies bill or declare extraction. The combination with S3, Lambda and Step Capabilities makes it straightforward to show Textract into an ingestion pipeline.
Strengths
- Dependable desk and key worth extraction for receipts, invoices and insurance coverage varieties.
- Clear sync and batch processing mannequin.
- Tight AWS integration, good for serverless and IDP on S3.
Limits
- Picture high quality has a visual impact, so digicam uploads might have preprocessing.
- Customization is extra restricted than Azure customized fashions.
- Locked to AWS.
Use when the workload is already in AWS and also you want structured JSON out of the field.
3. Microsoft Azure AI Doc Intelligence
Azure’s service, renamed from Kind Recognizer, combines OCR, generic format, prebuilt fashions and customized neural or template fashions. The 2025 launch added format and browse containers, so enterprises can run the identical mannequin on premises. The format mannequin extracts textual content, tables, choice marks and doc construction and is designed for additional processing by LLMs.
Strengths
- Greatest in school customized doc fashions for line of enterprise varieties.
- Containers for hybrid and air gapped deployments.
- Prebuilt fashions for invoices, receipts and id paperwork.
- Clear JSON output.
Limits
- Accuracy on some non English paperwork can nonetheless be barely behind ABBYY.
- Pricing and throughput have to be deliberate as a result of it’s nonetheless a cloud first product.
Use when it is advisable educate the system your individual templates or if you find yourself a Microsoft store that wishes the identical mannequin in Azure and on premises.
4. ABBYY FineReader Engine and FlexiCapture
ABBYY stays related in 2025 due to 3 issues, accuracy on printed paperwork, very extensive language protection, and deep management over preprocessing and zoning. The present Engine and FlexiCapture merchandise assist 190 and extra languages, export structured information, and might be embedded in Home windows, Linux and VM workloads. ABBYY can be robust in regulated sectors the place information can not depart the premises.
Strengths
- Very excessive recognition high quality on scanned contracts, passports, previous paperwork.
- Largest language set on this comparability.
- FlexiCapture might be tuned to messy recurring paperwork.
- Mature SDKs.
Limits
- License value is increased than open supply.
- Deep studying based mostly scene textual content isn’t the main focus.
- Scaling to tons of of nodes wants engineering.
Use when you should run on premises, should course of many languages, or should cross compliance audits.
5. PaddleOCR 3.0
PaddleOCR 3.0 is an Apache licensed open supply toolkit that goals to bridge photos and PDFs to LLM prepared structured information. It ships with PP OCRv5 for multilingual recognition, PP StructureV3 for doc parsing and desk reconstruction, and PP ChatOCRv4 for key data extraction. It helps 100 plus languages, runs on CPU and GPU, and has cellular and edge variants.
Strengths
- Free and open, no per web page value.
- Quick on GPU, usable on edge.
- Covers detection, recognition and construction in a single challenge.
- Energetic neighborhood.
Limits
- You should deploy, monitor and replace it.
- For European or monetary layouts you usually want postprocessing or superb tuning.
- Safety and sturdiness are your accountability.
Use when you need full management, otherwise you wish to construct a self hosted doc intelligence service for LLM RAG.
6. DeepSeek OCR, Contexts Optical Compression
DeepSeek OCR was launched in October 2025. It isn’t a classical OCR. It’s an LLM centric imaginative and prescient language mannequin that compresses lengthy textual content and paperwork into excessive decision photos, then decodes them. The general public mannequin card and weblog report round 97 % decoding accuracy at 10 occasions compression and round 60 % at 20 occasions compression. It’s MIT licensed, constructed round a 3B decoder, and already supported in vLLM and Hugging Face. This makes it attention-grabbing for groups that wish to cut back token value earlier than calling an LLM.
Strengths
- Self hosted, GPU prepared.
- Glorious for lengthy context and combined textual content plus tables as a result of compression occurs earlier than decoding.
- Open license.
- Suits trendy agentic stacks.
Limits
- There isn’t any commonplace public benchmark but that places it towards Google or AWS, so enterprises should run their very own checks.
- Requires a GPU with sufficient VRAM.
- Accuracy depends upon chosen compression ratio.
Use when you need OCR that’s optimized for LLM pipelines fairly than for archive digitization.
