How to convert a scanned PDF to Word
A scanned PDF is really a stack of images, so "converting" it to Word isn't one button — it depends on whether the file has a hidden text layer. This guide shows the 10-second test to find out, how to get a clean .docx in your browser with no upload, and exactly when you need OCR.
Most "convert scanned PDF to Word" tools ask you to upload your document to their server, run OCR, and hand back a .docx. That works — but your document (which is often a contract, invoice, or ID) leaves your device — which raises real safety questions. Convertissima takes a different approach: it converts entirely in your browser, nothing is uploaded. The trade-off is that you need to understand what kind of "scan" you actually have. It takes ten seconds to find out.
Step 1: Is it really scanned? The text-layer test
Not every PDF that looks scanned is image-only. Many "scanned" PDFs were already run through OCR by the scanner or by software, so they carry an invisible text layer on top of the image. Those convert beautifully.
To check: open the PDF and try to select a line of text with your cursor.
- Text highlights? Your PDF has a real text layer — it can be extracted directly (go to Step 2).
- Nothing selects, you only draw a box? It's a true image-only scan with no text (go to Step 3).
Why this matters: if there's no text layer, there is literally no text in the file to "extract" — only pictures of text. That's the difference between a quick conversion and needing OCR.
Step 2: If it has text — extract it in your browser
When the text-layer test passes, open the PDF to Word converter and choose one of these modes:
| Mode | What it does | Best for |
|---|---|---|
| Auto | Extracts text on text-heavy pages, renders scanned or empty pages as images. | Mixed documents — the safe default |
| Text only | Fast, plain text extraction with no page images. | Text-layer PDFs where you want editable text |
| Page images | Renders every page as a JPEG inside the .docx. | Image-only scans, forms, tables, charts |
For a PDF that has a text layer, Text only (or Auto) gives you selectable, editable text in Word — all processed locally. The conversion uses Mozilla's pdf.js to read the document and builds the .docx in the page.
Step 3: If it's image-only — Page-images mode, or OCR
For a true scan with no text layer, you have two honest options:
Option A — Page-images mode (private, no upload)
Use Page-images mode. Convertissima renders each page into the .docx as an image. You get every page — scans, forms, tables, charts — inside an editable Word file you can annotate, reorder, or drop into a larger report, and your file never leaves your device. The catch: the text won't be selectable, because there was no text to begin with.
Option B — OCR (when you need selectable text)
If you specifically need to edit the words of a scanned document, you need OCR (Optical Character Recognition), which turns pictures of text into real text. Convertissima does not perform OCR. For that step you'd use a dedicated OCR tool — and here's the honest privacy note the rest of the internet glosses over: most online OCR services upload your file. If the document is sensitive, prefer an offline/desktop OCR tool that keeps the file on your machine.
Rule of thumb: need the pages in Word, privately? Page-images mode. Need the words editable from a true scan? OCR — ideally offline if the document is sensitive.
Step 4: Open in Word and proofread
Open the downloaded .docx in Microsoft Word, Google Docs, WPS or LibreOffice. Then:
- Check the layout against the original — multi-column scans and complex tables can shift.
- Proofread key values: dates, amounts, names, account numbers.
- If extracted text looks garbled, the source likely had a poor-quality text layer — fall back to Page-images, or re-OCR a cleaner scan.
Get the cleanest result: scan quality tips
Conversion quality is capped by scan quality. Before you convert:
- Scan at 300 DPI or higher.
- Straighten and crop pages; remove black borders.
- For text-only documents, scan in black & white to boost contrast.
- Keep within Convertissima's limits: up to 60 MB / 150 pages for text modes, or 80 pages in Page-images mode.
FAQ
Can I convert a scanned PDF to Word without uploading it?
Yes. Convertissima converts PDF to Word entirely in your browser, so the file is never uploaded. If your PDF has a text layer, Auto or Text-only mode extracts the text; if it's an image-only scan, Page-images mode places each page into the .docx locally.
Does Convertissima use OCR on scanned PDFs?
No. Convertissima does not perform OCR. It extracts text that already exists in the PDF's text layer, and for image-only scans it renders the pages into Word as images. To get selectable, editable text from a true scan you need a separate OCR tool.
How do I know if my PDF is scanned or has real text?
Open the PDF and try to select a line of text with your cursor. If the text highlights, the PDF has a real text layer. If nothing selects and you can only draw a box over an image, it's an image-only scan.
What's the difference between Auto, Text-only and Page-images modes?
Auto picks text extraction for text-heavy pages and a page image for scanned or empty pages. Text-only does fast plain-text extraction. Page-images renders every page as a JPEG inside the .docx — great for scans, forms and tables, but it produces images rather than selectable text.
Why is my converted Word document just images instead of editable text?
That happens when the source is an image-only scan with no text layer and Page-images mode is used. There's no text to extract, so the pages are placed as images. To get editable text from such a scan, run it through OCR first.
How can I get the best results from a scanned PDF?
Start from a clear scan at 300 DPI or higher, straighten and crop the pages, and increase contrast for text-only documents. After converting, always proofread important values such as dates and amounts against the original.
Convert your PDF privately
To recap: run the text-layer test first. If there's text, Auto or Text-only gets you editable Word in the browser. If it's a true scan, Page-images puts the pages into Word with no upload — and only reach for OCR when you genuinely need the words editable. Either way, your document stays on your device.
