Searchable PDF vs TXT file: which should you keep?
By DeckleUpdated
Keep a searchable PDF when you need to find a document later and still see the original page: the signature, the stamp, the layout. Keep a TXT file when you only need the words, want to search across many documents at once, or will feed the text into another program. For records that matter, keep both: the PDF as the document, and a TXT made with PDF to text as a lightweight copy for search.

Searchable PDF or TXT: the short answer
| You want to | Keep |
|---|---|
| Prove what a page looked like, with signatures and stamps | Searchable PDF |
| Find a phrase and see it in context on the page | Searchable PDF |
| Search hundreds of documents with a desktop search tool | TXT, or both |
| Paste passages into notes, emails or reports | TXT |
| Count words, translate or analyse the wording | TXT |
| Send a document someone will print or file | Searchable PDF |
| Store years of statements in very little space | TXT alongside the PDF |
What each file holds
A searchable PDF is the page image or the page itself, plus a text layer you can search. If it came from a scan, the text layer was added by OCR and sits invisibly behind the picture. Search in any PDF viewer highlights the match on the page, so you can see exactly where it appears.
A TXT file holds only characters and line breaks. It opens in any editor on any device, it is tiny, and desktop search tools index it easily. It loses everything visual: fonts, images, signatures, tables as tables.
Example: a year of bank statements as 12 scanned PDFs might be 40 MB. After OCR, each PDF is searchable in a viewer. Extracting them with PDF to text gives 12 TXT files of a few hundred kilobytes in total. Searching the TXT files for a payee finds every month that mentions it; opening the matching PDF shows the statement itself.
How to make the TXT copy
- Make sure the PDF has selectable text. If it is a scan, run OCR on it first.
- Open PDF to text and choose the PDF, or drop it onto the page.
- Keep All pages and choose Mark where each page ended, so search results can be traced back to a page.
- Choose Extract text.
- Save the TXT file next to the PDF with the same name. Deckle names it after the PDF already, such as
statement-2026-03.txt.
Keeping the names identical means a match in the text file points straight to the PDF you need.
Accuracy is the same in both
If the text came from OCR, the PDF's search and the TXT file share the same recognised words, mistakes included. A misread name such as Srnith for Smith is unfindable in both. Extraction does not fix recognition errors and does not add new ones.
So if search matters, check the recognised text once, on the pages you are most likely to search: names, account numbers, dates. Native PDF text vs OCR text lists the usual misreads.
When to keep both
Keep both when the document is a record, such as a contract, statement, certificate or letter, and you want quick search across many of them. The PDF stays the authoritative copy; the TXT is a searchable index. Keep only the PDF when you search one document at a time in a viewer. Keep only the TXT when the look never mattered, such as notes or a transcript.
Tips
- Name the TXT after the PDF. One shared name makes it easy to go from a search hit to the page.
- Use page markers. They let you count which page a match is on.
- Keep the TXT in the same folder as the PDF. Any search tool that finds the text then leads you to the document beside it.
- Do not delete the scan. If OCR was poor, you can recognise it again; a TXT file cannot be turned back into the page.
Frequently asked questions
Is a searchable PDF better than a text file?
For keeping a document, yes, because it keeps the page. For searching or reusing the wording, a text file is lighter and works in more tools.
Can I turn a TXT file back into the original PDF?
No. The text file has no layout, images or signatures, so it cannot recreate the page.
Does a searchable PDF take more space?
Yes. It keeps the page images, so it is far larger than the text alone. The text layer itself adds very little.
Can PDF to text read a searchable PDF made by OCR?
Yes. It exports the OCR text layer like any other selectable text.
