Intelligent PDF Text Extraction
Extracts selectable text from digital PDFs with high fidelity. Automatically detects scanned pages and falls back to OCR at high resolution — no configuration needed. Multi-page PDFs processed in full.
Document Intelligence API
One API for Every
Document Task
Most document workflows require five or more separate tools — a PDF extractor, an OCR engine, a Word converter, an image processor, and a translation service, each with its own API key, pricing model, and failure mode. DocConvert consolidates all of them into one consistent REST API.
Everything Your Document Pipeline Needs — In One Service
Building document workflows typically means stitching together multiple services, each with its own integration cost, failure mode, and billing model. DocConvert is purpose-built to own the entire pipeline: ingestion, extraction, recognition, conversion, and translation — all behind a single API key and a consistent REST interface.
One API key. Every capability.
A single credential gives you access to every conversion endpoint — PDF extraction, OCR, Word conversion, image processing, and translation. No per-feature sign-ups, no rotating tokens across services.
Automatic OCR fallback — zero configuration
When a PDF contains scanned or image-only pages, DocConvert detects them automatically and switches to high-resolution OCR on the fly. You submit one file and always get text back — no branching logic in your code.
Deep multilingual recognition — 40+ languages
DocConvert applies the most accurate recognition model for each script family. CJK scripts (Chinese Simplified, Chinese Traditional, Japanese, Korean) use a deep-learning engine purpose-built for logographic text, returning detected language and confidence score alongside the extracted content.
Tables come back as structured data, not flat text
When a document contains tabular data — invoices, financial statements, forms — DocConvert extracts each cell individually and returns rows as typed 2-D arrays, ready to insert into a spreadsheet or database without post-processing.
Async queue built in — no infrastructure to run
Large documents submit as background jobs, are processed on a dedicated worker fleet, and land in S3. You poll a status endpoint and receive a pre-signed download URL on completion. No SQS queues, no worker servers, no S3 lifecycle policies to manage yourself.
Format-faithful Word-to-PDF conversion
Complex DOCX files — multi-column layouts, embedded images, custom fonts, tracked changes — are converted to PDF with formatting preserved. Each job runs in an isolated environment, so concurrent conversions never interfere with each other.
Extraction and translation in a single call
Submit a foreign-language PDF, TIFF, or scanned image and receive an English translation in one request. DocConvert handles the extraction, language detection, and translation pipeline internally — no chaining separate API calls yourself.
Your data stays on your infrastructure
All processing happens on dedicated servers — no third-party cloud OCR calls, no document content sent to external APIs. When self-hosted, files never leave your network perimeter. Ideal for regulated industries handling sensitive documents.
Comprehensive Document Intelligence — Every Format Covered
Each capability is a dedicated, tested REST endpoint. No configuration required — send your file, get your result. All processing runs on dedicated infrastructure with no third-party cloud calls.
Multilingual OCR — 40+ Languages
Auto-detects the dominant script and applies the most accurate recognition model for that script family — including deep-learning recognition for CJK scripts (Chinese, Japanese, Korean) that substantially outperforms general-purpose OCR on logographic text. Returns detected language and confidence score.
Structured OCR with Table Extraction
Detects table boundaries, extracts each cell individually, and returns rows as typed 2-D arrays alongside paragraph text — all in reading order. Ideal for invoices, financial statements, and forms.
Word to PDF — Format-Faithful Conversion
Converts DOCX files to PDF preserving fonts, images, tables, and complex formatting. Each conversion runs in an isolated environment to prevent cross-job interference. Handles large Word documents via the async job queue.
Image & TIFF Conversion
Converts JPEG and multi-frame TIFF images to PDF losslessly. Rasterises PDF pages to TIFF at up to 300 DPI for archiving or downstream OCR pipelines. Single-frame and multi-frame TIFFs supported.
Document Translation to English
Extracts text from PDF, TIFF, or JPEG and translates it to English in a single API call. Supports 10+ source languages with auto-detection. Async mode for large documents returns a JSON result file.
Supported Conversion Pairs
Every format pair is a dedicated endpoint. Async endpoints return a job_id; poll /status/{job_id} for the result URL.
| Input | Output | Endpoint | Mode |
|---|---|---|---|
| Plain text | /convert/pdf-to-text | Sync | |
| TIFF (300 DPI) | /convert/pdf-to-tiff | Async | |
| JPEG | /convert/jpeg-to-pdf | Sync | |
| TIFF | Plain text | /convert/tiff-to-text | Sync |
| TIFF | /convert/tiff-to-pdf | Sync | |
| DOCX | /convert/docx-to-pdf | Async | |
| JPEG / TIFF / PDF | OCR text | /ocr · /ocr/multilingual | Sync |
| JPEG / TIFF / PDF | Structured JSON + Markdown | /ocr/structured | Sync |
| PDF / TIFF / JPEG | English translation | /translate/document | Sync |
Integrate in Minutes — Standard REST, No SDK Required
Every endpoint accepts multipart/form-data. Pass your API key in the
X-API-Key header. Synchronous endpoints return the converted file as bytes;
async endpoints return a job_id to poll.
