What you provide
A scanned PDF or image-based document and OCR language selection.
What you get
Text output and, where supported, searchable PDF-style export.
Local processing
OCR processing runs in your browser after required OCR assets are available.
Limitations
Large files and mobile devices may process slowly; recognition quality depends on scan clarity.
What to expect

- OCR may require additional processing time on long documents.
- Always validate extracted text before compliance-critical use.
About OCR PDF
OCR PDF is designed for people who want a practical browser-first workflow instead of uploading files to a third-party service just to complete a routine task. OCR PDF runs in your browser for local, private document handling. Process files directly on your device without a server-side upload step for core workflows. Run OCR on scanned PDFs locally in your browser and export searchable PDF or text output. No uploads.
OCR processing runs in your browser after required OCR assets are available. That matters when you are handling work files, drafts, forms, exported data, or other material that should stay under your control until you decide to share the result. It also removes the usual upload delay, which keeps the workflow lighter and easier to repeat when you need to adjust settings and try again.
In most cases, people use OCR PDF to prepare documents quickly before sharing or archiving. handle privacy-sensitive files without third-party upload workflows. Before you publish, archive, or forward the output, do a quick review of the result because large files and mobile devices may process slowly; recognition quality depends on scan clarity.
How it works
- 1. Add the file or inputs you want to process in the OCR PDF workspace.
- 2. Choose the settings that match the output you want before starting the run.
- 3. Run OCR PDF directly in your browser and wait for the local processing step to finish.
- 4. Download the result and review it before sharing, archiving, or sending it onward.
Why use local browser tools
Local browser workflows reduce exposure for private files because the main processing path runs on your device instead of starting with an upload to a third-party service. That is useful when the document, image, text, or encoded payload contains work material, customer data, or anything you would rather review locally before sharing.
Browser-based tools are also direct. You open the file, run the operation, and download the result without waiting for remote queues or account-gated limits. You can review Plain.tools privacy claims in Verify Claims.
