PDF OCR

Model:
Turn a scanned PDF into selectable, searchable text. Rasterizes each page at 200 DPI and runs OCR — pick Tesseract (fast, free), GOT-OCR2 (better for multi-column + tables), or premium fal OCR (best for degraded / historic scans). Output as .txt, .docx, or page-labelled text. Got an image, not a PDF? Use /ocr/ →

When to use PDF OCR

    

        
Invoices + receipts
Turn a stack of scanned invoices into editable text for bookkeeping, reimbursements, or AP automation.

        
Old books + archives
Digitize out-of-print books, historic documents, or library archives into searchable text.

        
Legal + medical records
Unlock text inside scanned case files, medical reports, or faxed documents for discovery + eDiscovery workflows.

        
Before translation
Run OCR to extract text, then feed the result into /pdf/translator/ for any-to-any language conversion.

PDF OCR — FAQ

                

                    
                    

                        

                            
                        

                        

                            
Turn scanned PDFs (image-only, unselectable text) into searchable, copyable, AI-readable text. Upload a PDF of scanned pages — invoices, contracts, old books, handwritten notes — and get back plain text, .docx, or page-numbered text.

                        

                    

                    
                    

                        

                            
                        

                        

                            
About 500 tokens per page on our self-hosted Tesseract OCR (free-tier). GOT-OCR2 costs ~800/page and handles complex layouts (multi-column, tables, equations) better. Premium fal OCR runs ~2,500/page for the highest accuracy on degraded scans. 800-token floor on all three so 1-page uploads are not pure overhead.

                        

                    

                    
                    

                        

                            
                        

                        

                            
Tesseract (default, free) for clean printed scans. GOT-OCR2 (free, slower) for multi-column research papers, scientific equations, or Asian-language documents — it has a much better layout model. Premium fal OCR only for degraded / low-resolution / historic scans where every pixel matters.

                        

                    

                    
                    

                        

                            
                        

                        

                            
Tesseract supports 100+ languages including Latin, Chinese, Japanese, Korean, Arabic, Cyrillic, Hebrew, Hindi, Thai, Vietnamese. Pass a language hint (eng/spa/fra/deu/jpn/chi_sim/ara/etc.) for 30-50% better accuracy — auto-detect works but is slower.

                        

                    

                    
                    

                        

                            
                        

                        

                            
Three: .txt (plain, one file for the whole document), .docx (Word with page breaks preserved), and page-wise .txt (===== Page N ===== headers between pages so you can find a specific page in the output).

                        

                    

                    
                    

                        

                            
                        

                        

                            
On clean 300-DPI scans, 99%+ on printed Latin script. Drops to 90-95% on 150-DPI scans, faded documents, or handwriting. Non-Latin scripts (Chinese, Arabic, Hindi) do much better with a language hint and GOT-OCR2 rather than Tesseract.

                        

                    

                    
                    

                        

                            
                        

                        

                            
Handwriting OCR is much harder than printed text — expect 70-85% accuracy even on the premium OCR. For clean hand-printed forms (not cursive) on white paper, Tesseract is usable. For cursive / messy notes, premium fal OCR with the handwriting mode is more reliable.

                        

                    

                    
                    

                        

                            
                        

                        

                            
About 1-3 seconds per page on Tesseract, 3-5 seconds on GOT-OCR2, 5-10 seconds on premium fal. A 50-page scanned book takes 1-3 minutes — the heavy-task banner lets you close the tab and get the result emailed when it finishes.
