OCR API for Images and PDFs

The API page is for teams that need automated OCR, webhooks, JSON output, repeatable batch jobs, and clear document retention rules.

A useful OCR API should accept images and PDFs, return status codes that expose failures, and provide structured output with page-level metadata.

Unlimited marketing does not belong in an API contract. Use fair-use limits, retries with backoff, and idempotency keys for repeated uploads.

Document APIs must say whether files are stored, how long they remain available, and whether content is used for training.

OCR API for Images and PDFs helps when text is visible but locked inside an image, scan, PDF page, receipt, invoice, screenshot, or archived document. Use it to reduce retyping first, then decide whether the result belongs in TXT, Word, Excel, Markdown, JSON, CSV, or a searchable PDF workflow.

OCR API for Images and PDFs works best with high-resolution scans, sharp screenshots, straight pages, strong contrast, and files that are not heavily compressed. If the first result looks weak, crop the page, rotate it upright, improve contrast, and rerun OCR before blaming the text engine.

Start with copyable TXT because it is the fastest review format. Move to Word or DOCX when you need editable paragraphs, Excel or CSV when rows and totals matter, Markdown for notes and OCR for RAG, JSON for automation, and Searchable PDF or PDF/A when the original scan must remain searchable as an archive.

Check names, dates, totals, invoice numbers, tables, handwriting, stamps, watermarks, and low-contrast areas before relying on OCR output. OCR saves typing, but important legal, medical, finance, and identity documents still need a human review pass.

For receipts and invoices, verify merchant, vendor, date, subtotal, tax, total, currency, line items, and payment terms. For contracts, verify names, clause numbers, signatures, dates, and page order. For research and books, verify headings, citations, tables, footnotes, and reading order.

The browser workflow keeps files on your device when local OCR is available. If you choose any advanced cloud OCR mode, look for clear upload disclosure, short retention windows, deletion rules, encryption, and a promise that files are not used for training.

OCR API for Images and PDFs often connects to Batch OCR for many files, PDF OCR for scanned documents, Make PDF Searchable for text-layer archives, OCR to Excel for tables, and PDF to Markdown OCR for AI notes and document search.
