About this tool: OCR PDF
OCR PDF recognizes text from image-based PDF pages using a lazily loaded browser OCR engine. This build focuses on editable text extraction, not layout-perfect PDF reconstruction.
How it works
PDF pages are rendered to images and passed to the OCR engine page by page.
Practical example
A scanned invoice with no selectable text can be converted into editable text for copying into another document.
Important notes
OCR accuracy depends on scan quality, language, orientation and typography. The current preset uses English recognition.
Privacy & processing
OCR runs locally in the browser after the OCR engine is loaded.
Frequently asked questions
Does OCR PDF upload my file?
No. This Phase 14 implementation performs the advertised processing in the browser unless the page explicitly states otherwise.
What files work with OCR PDF?
Use a normal PDF within the browser size limits shown by the uploader. Unsupported, encrypted or severely corrupted files can return a clear error.
Can I use OCR PDF on a phone?
Yes. The interface is responsive, although larger PDFs can require more memory and processing time on mobile devices.
Will the output always look identical to the source?
Not always. The exact result depends on the operation and the PDF structure. NexterHub explains transformations that can change text, layout or image quality.
What should I do if processing fails?
Try a smaller or different PDF, remove password protection where required, and confirm that the file opens normally in a standard PDF viewer.
