Understanding PDF Optical Character Recognition (OCR)

When physical documents, books, contracts, receipts, or medical records are scanned into PDF format, they are typically stored as a sequence of full-page raster images (JPEG, PNG, or TIFF). Because there is no underlying text encoding or font stream, standard PDF readers cannot select sentences, highlight passages, or perform keyword searches with Ctrl + F.

Our In-Browser PDF OCR Studio leverages state-of-the-art WebAssembly neural networks powered by Tesseract.js v5 and PDF-Lib. It recognizes character glyphs, calculates precise word bounding boxes $(X, Y, \text{Width}, \text{Height})$, and injects an invisible text layer (opacity: 0.0) directly over the original page canvas. This technique guarantees 100% visual fidelity without re-compressing or rasterizing vector artwork.

Frequently Asked Questions (FAQ)

What is a Searchable PDF?

A searchable PDF contains both the original visual page image and a hidden text layer aligned underneath or on top. This lets you select, copy, and search (Ctrl+F) recognized words while keeping the authentic look of the original scanned document.

Are my confidential documents uploaded to your server?

No. IMGFixy utilizes 100% client-side WebAssembly OCR (Tesseract.js v5). Your PDF files, scanned images, and extracted text never leave your computer or browser memory.

Does OCR degrade the visual quality of my original PDF?

Not at all. The original visual streams are preserved losslessly. We inject transparent text with zero opacity (opacity: 0.0) directly over the page coordinates, ensuring 100% visual retention.

Can I OCR multi-language documents (e.g. English and Hindi)?

Yes! You can choose combination language models such as English + Hindi or select specific Indic, European, and Asian language packages from the dropdown menu.

What should I do if my document is already partially searchable?

Our tool automatically scans your PDF upon upload and badges each page as either Searchable (Native Text) or OCR Required. You can click the "Scanned Only" button to process only non-searchable pages.

What resolution (DPI) is used for character recognition?

We offer three presets: Fast (150 DPI), Balanced (200 DPI, recommended default), and High Accuracy (300 DPI with adaptive contrast filtering for faded or small-print documents).

Can I export plain text (.txt) without the PDF wrapper?

Yes. After processing, the result screen offers both a "Download Searchable PDF" button and a "Download Plain Text (.txt)" button, as well as a one-click clipboard copy feature.

Does this tool work on mobile devices and iPads?

Yes. The interface is 100% responsive and touch-friendly, running smoothly on modern mobile browsers including Safari on iOS and Chrome on Android.

Can it process password-protected PDFs?

Yes. If your document is encrypted with a password, an in-browser prompt will appear allowing you to unlock and process the file seamlessly.

Is there any page limit or file size fee?

No. IMGFixy PDF OCR is 100% free with unlimited document processing and no subscriptions or watermarks.
