Why ConversionTab matters for Polish PDFs
When Polish characters are dropped, names and cities can become inaccurate. ConversionTab lets users choose Polish OCR and extract editable text, which is especially useful for official forms, invoices, certificates, and academic documents.
| OCR risk | Why it matters |
|---|---|
| Michał → Michal | Name becomes inaccurate |
| Łódź → Lodz | City name loses correct spelling |
| Załącznik → Zalacznik | Official term becomes weaker |

Workflow: from PDF to usable text
Before you upload
- Export or scan at a steady resolution; avoid heavy shadows across text.
- Crop to the page region you need—wide empty margins slow OCR and can pull in noise.
- If the PDF mixes Polish with another script, plan to select every language you can see in the picker.
In ConversionTab
Upload the PDF, choose Polish (plus any other languages on the page), turn on text from images when the file is scanned or flattened, then extract. Copy to your editor or download a .txt file for the next step in your workflow.
When to enable “text from images”
Use it whenever highlight-and-copy fails in your PDF viewer, when text appears as a picture, or when exports from scanners or mobile cameras produce image-only pages. Native text layers can stay off for faster runs, but scans almost always need OCR.
Mixed-language and noisy pages
Diacritics (ą, ę, Ł, ź, ż) are legally significant—use a sharp scan and confirm names and city spellings character by character.
For tables, stamps, signatures, and watermarks, expect to tidy spacing and line breaks manually. OCR prioritizes readable characters over perfect layout preservation.
Scan and export checklist
| Signal | What to try | Why it helps |
|---|---|---|
| Blurry small type | Re-scan at 300 DPI, reduce glare | Sharper edges for Polish letterforms |
| Skewed photo | Straighten before PDF or rotate pages | Improves line reading order |
| Colorful background | Print to flattened greyscale test | Improves contrast for OCR |
| Password protection | Unlock locally, then extract | Engines cannot OCR locked content |
Diacritics that flip meaning on Polish forms
Polish uses several letters that look like “plain” Latin neighbors until you zoom. A wrong ł vs l or ą vs a can invalidate an address or personal record. After extraction, prioritize fields that will be hashed or searched—those need exact grapheme matches.
Count digits; compare control positions to the PDF.
Watch for merged cells in gmina listings.
