Image to Searchable PDF - OCR Text Layer Generator

A regular image PDF is a flat picture wrapped in a .pdf container — you cannot select, copy or search the text in it. A searchable PDF has an invisible OCR text layer aligned behind every visible character, so Ctrl+F finds words, Copy works, and screen readers can read the page aloud while the visual appearance stays identical.

The OCR engine reads every word and stores its text and bounding box behind the original image at the exact pixel coordinates. Visually the page looks identical to the original scan, but Adobe Acrobat, Preview, Chrome and every modern PDF viewer can now select, search and copy the text as if it were native digital text.

Yes. The text layer is standard PDF (no proprietary extension), so Adobe Acrobat (Reader and Pro), macOS Preview, Chrome's built-in PDF viewer, Firefox, Edge, and mobile readers like Files app, Drive and Dropbox all index and search it. Ctrl+F or Cmd+F finds words within seconds, even in long scanned reports.

Yes. Pass multiple language codes (for example eng+chi_sim+hin) and the OCR considers all of them when reading characters. Mixed-script documents like bilingual menus, international contracts and government forms work cleanly. For best results give the most-likely language first in the list.

The text layer typically adds 5–15% to the PDF size — usually a few hundred kilobytes per 100 pages. Compared to the gain (full-text search across your entire document archive), it is a small price. If size matters for email, run the result through PDF Compress to trim large embedded images further.

Uploads are processed in a temporary working folder and auto-deleted within minutes of the conversion completing. We never train models on user files, never share them, and never add watermarks. That makes the tool safe for legal, HR, medical and accounting scanned archives where confidentiality matters most.
