Production-Grade OCR

Built to Actually Solve the Problem

Image-based PDFs can't be searched, copied from, or read by a screen reader. They're digital files that don't behave like digital text.

DocStrata fixes that.

Core Features

DocStrata converts image-based PDFs into searchable documents you can actually use. Here's what sets it apart from basic OCR tools.

High-Quality OCR

Superior OCR Processing

DocStrata is built on Tesseract's LSTM neural network, tuned to extract more usable text from image-based PDFs than standard OCR setups.

4.5x More Text Extracted

DocStrata extracts up to 4.5x more text than basic OCR tools on the same documents.

An Invisible Text Layer

The file looks identical to the human eye. Underneath, DocStrata adds a text layer you can search and copy-paste from, just like a Word document.

More Functional PDFs

The result is a PDF that behaves like a digital document, not a picture of one.

35+ Languages Supported

English, Spanish, French, German, Chinese, Japanese, and Hindi are just a few of the 35+ languages DocStrata supports.

Multiple Languages In One PDF

For a document that's part English, part Spanish, select the eng+spa option and DocStrata converts both in the same pass.

Auto Language Detection

Not sure what language a PDF is in? DocStrata detects it for you.

Smart Preprocessing

Smarter Processing of Images

Tilted images, upside-down pages, and rough scans are common in real-world documents. DocStrata corrects all of it automatically.

Just upload the document — no manual cleanup required.

Auto-Rotation
Pages rotated 90°, 180°, or 270° are automatically detected and corrected.
Deskewing
Crooked scans and misaligned corners are straightened automatically before text extraction.
Background Cleaning
Watermarks, stamps, and scan noise are removed so they don't interfere with text recognition.
DPI Optimization
Low-quality scans are upsampled intelligently, turning them into sharper, more readable images before OCR runs.

Built for Everyday Use

Features designed around how people actually process documents day to day.

Easy Page Selection
Only need part of a document converted? Specify pages using simple syntax like 1-10, 15, or 35-40, and DocStrata converts just those pages — saving you time and credits.
Optimize Files
Output files are compressed with JBIG2 and pngquant to keep file sizes down without sacrificing quality. Skip PDF/A conversion when you need faster turnaround instead.
Real-Time Monitoring
Track conversion progress in real time via our REST endpoint and Server-Sent Events, with status updates like "Processing page 7 of 23" so you always know where things stand.
Large File Limits
Upload PDFs up to 50 MB — a limit set after testing against hundreds of real-world image-based PDFs, so it covers nearly every file you'll encounter.
Automatic Deletion
Uploaded files are automatically deleted within 24 hours — no action required on your part.
Security & Privacy
Files are gone in 24 hours, access tokens expire automatically, and there's no long-term data retention — built for sensitive documents by default.

Real-World Applications

DocStrata is used across a range of document-heavy workflows.

Document Digitization
Digitize old contracts and business documents, and copy-paste text directly from scanned files. DocStrata helps you:
  • Fully digitize paper archives
  • Copy and reuse text from scanned files
  • Build a searchable records archive
Handling Multilingual Documents
Convert international contracts and multi-language PDFs to make them usable across teams worldwide. That means:
  • Transparent, searchable contract processing
  • Mixed-language documents handled in one pass
  • Easier collaboration across multilingual teams
Breathing Life Into Low-Quality Scans
Recover readable text from photocopies and low-quality scans that other OCR tools give up on. DocStrata:
  • Extracts text from barely readable photocopies
  • Corrects image alignment issues
  • Removes image noise before extraction
Bulk Document Digitization
Page selection makes digitizing manuals and other large, complex documents practical. You can save time and credits by:
  • Selecting specific pages for conversion
  • Converting the most important pages first
  • Paying only for what you actually need converted
