Common tasks
Choose a workflow for your document
I cannot copy this text
Use Image to Text or Screenshot to Text when a photo, chat screenshot, dashboard, or scanned page looks readable but behaves like a picture.
Ctrl+F finds nothing
Use PDF OCR to extract text from a scanned PDF. The searchable PDF guide explains how a separate tool can add a text layer.
I have too many files
Use Batch OCR when the real problem is thirty invoices, a folder of scans, or a long PDF that would otherwise become page-by-page work.
I need structured output
Read the Excel, Markdown, and API guides to plan the next step. Current browser output is copied text or TXT, not tables, JSON, CSV, or API responses.
The file is sensitive
Use browser-first OCR for contracts, medical papers, bank statements, tax files, IDs, and HR documents before choosing any cloud OCR mode.
I care about accuracy
Use the accuracy checklist before rerunning blurry photos, low-contrast scans, handwriting, stamps, watermarks, and complex tables.

Accuracy
How to get cleaner OCR results
Use high-resolution scans
Sharp text, straight pages, strong contrast, and minimal shadows produce cleaner OCR than compressed phone photos.
Review difficult scans
Handwriting, stamps, watermarks, low contrast, and unusual fonts still need human review before legal, finance, or medical use.
Choose the right format
Use searchable PDF for archives, TXT for copy-paste, Markdown for notes, CSV for tables, and JSON for automation.
Keep privacy explicit
Browser OCR keeps files local. Cloud OCR should clearly state upload, deletion, retention, and training policies.
Guide
OCR engines, formats, and limits
OCR output formats
UnlimitedOCR currently provides copied text and TXT download. Other formats need a separate conversion step or tool: Word and DOCX for editable documents, Excel and CSV for reviewed tables, JSON for structured data, Markdown for notes or RAG, and searchable PDF for a document text layer. None of those formats is an export option here.
OCR engines compared
Browser OCR and Tesseract.js handle private local extraction. PaddleOCR suits multilingual and table-heavy documents. OCRmyPDF adds text layers to create searchable PDF output. Mistral OCR, Google Document AI, and Amazon Textract offer cloud document parsing for enterprise use. Baidu Unlimited-OCR and DeepSeek-OCR target long-horizon document OCR research.
Transparent limits
Browser OCR has no page counter, but file size, page count, and device memory still set real limits. A fair-use cloud OCR API should use webhook callbacks, retries with backoff, idempotency keys, and clear retention rules. Files are not used for training. Page-by-page processing keeps progress visible and failures traceable.
FAQ
FAQ about Unlimited OCR
What is Unlimited OCR?
Unlimited OCR is a browser-first OCR workspace that converts images and PDFs into editable text without a server-side page counter.
Is this OCR tool really free?
The browser workflow is free to use. Your device performs the OCR work, which removes the usual server cost behind strict free-tier limits.
Do I need to create an account?
No. The current tool works without signup, passwords, or account setup.
Are my files uploaded?
The live image and PDF workflow keeps files in the browser when Tesseract.js and PDF.js load correctly.
Can I OCR multiple files at once?
Yes. Select multiple images or PDFs and the queue processes them one by one with visible status.
Can I make a PDF searchable?
No. This tool extracts text and downloads TXT; it does not add a PDF text layer or export searchable PDF. The separate guide explains how to evaluate tools that support that output.
Which languages are supported?
The default workspace ships with English OCR. Additional Tesseract language packs can be added as the site expands.
What is Baidu Unlimited-OCR?
Baidu Unlimited-OCR is a 2026 open-source model focused on long-horizon document parsing. This site is independent and uses a browser-first tool for the live demo.
Can OCR read handwriting?
Some handwriting can be recognized, but accuracy varies strongly by writing style, contrast, and scan quality.
Is there an OCR API?
There is no public OCR API today. The browser tool supports local text extraction and TXT download; teams with recurring batch needs can contact support to scope a paid pilot.
