Why Chinese PDF extraction needs a dedicated page
A small blur can merge Chinese strokes and change recognition quality. Generic OCR explanations are not enough for Chinese users. This page should educate users that high-resolution scans, proper cropping, and clear character edges are essential.
Small characters
Internal strokes may disappear in low-resolution scans.
Tables
Forms may extract text but lose structure.
ConversionTab role
It gives a simple extraction route while helping users prepare better input.

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 Chinese (Simplified) with another script, plan to select every language you can see in the picker.
In ConversionTab
Upload the PDF, choose Chinese (Simplified) (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
Dense characters and thin strokes need even lighting; mixed simplified/traditional pages should include every script you see.
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 Chinese (Simplified) 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 |
Simplified text beside Latin model numbers
Manuals and spec sheets alternate Chinese sentences with English part codes. OCR may reorder short Latin runs relative to the Chinese clause. After extraction, anchor each model number to the nearest Chinese heading by eye before you publish.
Thin strokes on glossy paper: rescan with less glare before a second OCR pass.
If a few traditional characters appear, include that script in language selection where supported.
Vertical notes may land at the wrong end of a paragraph—split manually.
