PDF OCR
识别文字，生成可搜索 PDF
Turn scanned documents and image-only PDFs into real text with OCR. PDF OCR runs text recognition over every page and writes an invisible text layer back into the file, so you can select, copy, and search what used to be a picture.
处理选项
怎么用PDF OCR
- Upload the scanned PDF (or a PDF exported from a scanner, camera, or fax).
- Choose the language the text is written in.
- Download the searchable PDF and search or copy the text.
Key features
Scans become searchable
Each page gets a hidden text layer, so Ctrl+F and copy-paste finally work on scanned paperwork.
Multi-language recognition
Pick the language of the document — English, Chinese, Japanese, Korean, Spanish, French, or German — for far better accuracy than auto-detect.
Keeps the original layout
The visible page stays exactly as it was; OCR only adds the text layer underneath.
Pays by the page
Credits are charged per page processed, so a two-page scan costs a fraction of a hundred-page report. No subscription required.
常见问题
What is OCR?
Optical character recognition reads the shapes of letters in a scanned image and converts them into machine-readable text. Without it, a scanned PDF is just a picture.
Does OCR change how the PDF looks?
No. The scanned image stays visible and unchanged; OCR adds an invisible text layer on top of it.
How much does it cost?
One credit per page. A 5-page scan uses 5 credits, so you only pay for the pages you actually process — there is no subscription.
Which languages are supported?
English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, French, and German are available in the menu, and recognition works best when you match the document language.
Will OCR work on a photo of a document?
Yes, as long as the photo is reasonably sharp and not too skewed. Convert the photo to PDF first, then run OCR on it.
Are my files kept?
No. Files are processed over HTTPS and removed automatically after conversion.
