OCR PDF

Turn scanned pages into a PDF you can search and select. Review the text before exporting.

Choose files or drop them here

Files and text stay in this browser. No account, upload or watermark.

Workspace: up to 4 files, 64 MiB, 400 pages and one million text characters. Each PDF: 20 MiB/200 pages; each image: 15 MiB/8 million pixels. OCR: 12 pages per run. These are device-safety budgets, not daily quotas. Export and clear to start another batch.

How to use this tool

  1. Choose up to four PDFs within the workspace limits. Native text is extracted first; pages without usable text are flagged.
  2. Choose the pages that need recognition and select English or Spanish. Adjust rotation, contrast or a region when necessary.
  3. Compare the source preview with recognized text. Correct mistakes and exclude pages outside your task.
  4. Download one searchable PDF, or open Batch exports for a ZIP with separate PDFs and TXT files. The invisible text contains your reviewed wording; the visible scan remains an adjusted page image.

The scanned/image example contains 19 known words; the native text example contains 5. These are fixture results, not a general accuracy guarantee.

Questions and useful limits

Does this upload my PDF?

No. Extraction, recognition and export run in your browser. Recognition downloads the chosen language and engine assets from Taskono, without sending document content.

Will the exported PDF look exactly the same?

Unchanged native pages are copied. Recognized pages use a bounded-resolution image and invisible text. This preserves their visible appearance where practical, but is not a lossless reconstruction. Changes to OCR text do not change the visible scan.

Can I correct text before export?

Yes. Review every important word and number. Word positions are reused when possible; major text edits can reduce text-selection alignment. Searchability does not guarantee recognition accuracy.
