Make a Scanned PDF Searchable

A scanned PDF is a stack of photographs. Searching finds nothing and you cannot copy a sentence. OCR reads every page and gives you two things: the plain text, and a copy of the same PDF with an invisible text layer laid over the scan.

After reading

Plain text for every page

Searchable PDF, original pages untouched

What the tool does

Two Outputs From One Scan

Plain Text

Every page read into one editable text box you can correct, copy or save as a TXT file.

Searchable PDF

The original pages exactly as they were, with an invisible text layer on top so search and text selection work in any PDF reader.

Per-page Feedback

Each page reports its character count and confidence while the job runs, so a bad scan shows up immediately rather than at the end.

Use cases

Documents You Cannot Search

📜

Contracts and Agreements

Find a clause by searching for it instead of scrolling through twenty scanned pages.

🏦

Statements and Invoices

Pull figures and reference numbers out of a scanned statement without retyping them.

🗄

Archives and Records

Old paper records become genuinely searchable, which is usually the whole point of digitising them.

🎓

Course Material

Photocopied handouts and lecture notes turn into quotable, searchable text.

How it works

What an Invisible Text Layer Is

A searchable PDF does not replace your scan. The page images stay exactly as they are, and a second copy of every word is written on top of them in transparent text, each word positioned over the place it appears in the picture. On screen the page looks identical, but the reader now has real characters to search, select and copy.

This is why the file grows only slightly — the layer is text, not another image. It is also why the quality of your scan matters: the layer can only be as accurate as the reading behind it, and a word the engine misreads will be searchable under the wrong spelling.

Privacy and responsible use

The Document Stays on Your Device

  • Rendering, reading and writing all happen inside your browser; the PDF is never uploaded to Bubixo.
  • Nothing is stored on a server, which matters for contracts, statements and medical documents that should not be handed to a third-party service.
  • The libraries are served from Bubixo's own domain, not a public CDN.
  • Only process documents you own or have permission to read.

⚠ Good to know

Check Before You OCR

If you can already select text in your PDF, it is not a scan and you do not need OCR at all — the text is in the file. Try selecting a word first; that one check saves a lot of time.

Pages are processed one after another and the limit is 50 pages and 40 MB per file. Longer documents are read up to that limit and the page tells you so rather than cutting off silently. A clean 300 dpi scan reads far better than a phone photo of a page taken at an angle.

Frequently asked questions

PDF OCR FAQ

Will the searchable PDF look different from my original?

No. The page images are copied across untouched and the text is written in invisible render mode on top. Page size and appearance stay identical; only the file size changes slightly.

Does it handle Turkish characters in the searchable layer?

Yes. A Unicode font is embedded into the output, so words containing ı, ğ, ş and İ are stored correctly and can be found by searching.

How long does a document take?

Roughly a second or two per page on a normal laptop, so a ten-page scan is done in well under a minute. Pages are handled one at a time to keep the browser responsive.

Is my PDF uploaded anywhere?

No. Everything runs in the browser tab. That is the main reason to use this for a contract or a bank statement rather than a service that processes files on a server.

Can I OCR a password-protected PDF?

Not while it is protected. Remove the password first with the unlock tool, then run the OCR.
