What OCR PDF does
Run English OCR on up to twelve PDF pages and create a rasterized searchable copy. The tool keeps the operation focused and creates a separate result so the original remains available for comparison.
OCR PDF processes the supplied input in the browser unless its interface explicitly identifies a browser-managed service.
How to use OCR PDF
Use a copy or a reproducible sample when trying OCR PDF. Select the relevant options, create the result, and compare it directly with the original input.
- Choose the PDF or source files and confirm page count, order, orientation, and whether the document is encrypted or scanned.
- Apply the smallest required page, form, annotation, conversion, optimization, or security change.
- Inspect every affected page in the preview and verify page-specific options rather than assuming all pages match the first.
- Download and reopen the result in a second PDF reader, then test search, forms, links, printing, or permissions as relevant.
Where OCR PDF fits
Use this PDF workflow when pages need a focused change for review, printing, sharing, accessibility, or another document system. PDFs can contain forms, fonts, annotations, images, links, and security settings, so a visually correct first page does not prove the entire document is correct.
What to check
Proofread recognized text against the page image, especially names, columns, punctuation, and low-contrast scans. OCR makes text searchable but does not certify accuracy.
Open the result in a second PDF reader and inspect page count, page order, fonts, forms, links, searchability, and print layout. OCR and reconstructed layouts should be proofread against the source.
Privacy and limitations
Browser PDF operations keep document bytes on this device. A tool is labeled as server-side when it requires a bounded external process.
OCR uses the bundled English model, accepts at most twelve pages, and creates a rasterized searchable copy. Recognition can be wrong, and original vectors, forms, links, signatures, and exact page structure are not preserved.
