Notes
- Searchable PDF rasterizes each page and overlays an invisible OCR text layer — text becomes copyable / searchable in most readers.
- Non-Latin scripts (CJK, Arabic, etc.) are fully supported in the Plain text output. The searchable-PDF text layer embeds Helvetica and may not faithfully reproduce non-Latin characters; the visible page image is intact regardless.
- Long PDFs can take a while — each page is rendered, OCR'd, and re-embedded locally.
Why run PDF OCR in the browser?
Scanned contracts and ID packs are exactly the documents you should not upload to a random OCR SaaS. This tool renders PDF pages and runs Tesseract.js (WebAssembly) locally to produce searchable text or a searchable PDF workflow depending on the UI. Language data (~10 MB per language) downloads on first use and can be cached afterward. On-device OCR keeps sensitive scans inside your machine.
How to OCR a PDF offline-friendly
- Drop a scanned or image-based PDF.
- Select OCR language(s); first use downloads the language pack.
- Start OCR and wait while each page is recognized in this tab.
- Copy text or download the result the tool provides.
Frequently asked questions
How accurate is browser OCR?
Tesseract does well on clean, high-contrast scans and typed pages. Handwriting, heavy skew, or low DPI
reduce accuracy. Rescan at 300 DPI when possible.
Are document images uploaded?
No. Page bitmaps and recognition run in-browser. Only the open-source language model files may download
from a CDN on first use — not your PDF content.
Which languages are supported?
Whatever language packs the UI exposes via Tesseract. English is typical by default; add packs as needed.
Can I OCR a photo of a document?
For single images, try the Image to Text tool. This page is optimized for multi-page PDFs.
