OCR PDF when a scan looks fine but you cannot select or search the text. AllToolHub runs OCR in the browser with an offline-friendly engine so many jobs never need a cloud OCR API.
Best results come from upright, high-contrast scans at reasonable resolution. Skewed phone photos, stamps over text, and tiny fonts reduce accuracy—rotate and crop first when you can. After OCR, proofread names, numbers, and legal amounts before you rely on them.
Use Extract Text from PDF instead when the file already has a real text layer and you only need a fast copy. Use OCR when the PDF is image-only or the text layer is missing or broken.
Upload a scanned or image-only PDF.
Choose OCR language if multiple options are available.
Run OCR — Tesseract runs offline in your browser (first run may download language data).

Yes. OCR PDF on AllToolHub is free, requires no account, and is built to run in your browser without a paid plan or watermarks from us.
Processing is designed to happen locally in your browser whenever possible. PDF bytes are processed in the browser whenever possible so drafts and contracts stay on your device. Standard web hosting may still log technical page requests, not your file contents.
After the first visit, the Progressive Web App cache can keep many pages available offline. Tool scripts must be cached first; heavy libraries load when you open the tool.
Modern Chrome, Edge, Firefox, Safari, and mobile equivalents. Some advanced file or crypto features need a recent browser version.
Keep an original backup before irreversible edits like compression or permanent page deletes. Related tools appear in the sidebar if you need a neighboring workflow.
Yes — recognition runs with Tesseract in your browser. Pages are not uploaded to AllToolHub for OCR.
English language data is bundled by default. Additional languages depend on which traineddata files are available in the tool.
Yes. After the English language model is cached from this site (first visit), recognition runs entirely in your browser with Tesseract — files are never uploaded for OCR.
Prefer Extract Text from PDF for digital documents. OCR is for image-only or scanned pages without a text layer.
