Apdf vs OCR.space

Apdf generates and tracks PDFs through an API, sending reader activity to apps or AI agents. PDF operations include HTML-to-PDF generation, merging, splitting, compression, watermarking, OCR, and password security. Reader analytics report opens, page reads, time spent, downloads, prints, and other events. Tokenized recipient links associate activity with named readers and can be deactivated or revoked. Recipients use a hosted browser viewer without installing an app or plugin; they can annotate PDFs and submit form fields, with captured information delivered as structured data. Event-based automations send webhooks to external endpoints. The site describes MCP connections for Claude, ChatGPT, Cursor, and Gemini, alongside webhook examples involving Slack, HubSpot, Pipedrive, and S3. Apdf says data is hosted in the EU, encrypted in transit and at rest, and handled in a GDPR-compliant manner. The free Hobby plan includes 3 tracked documents and 500 PDF operations per month. Pro costs $39 a month, billed $39 / mo; Business costs $149 a month, billed $149 / mo.

OCR.space converts images and PDF documents into editable text through an online OCR service and API, and can create searchable PDFs. The web service accepts JPG, PNG, GIF, and PDF files without registration; its free web uploads are limited to 5 MB per document. The API returns extracted text in JSON and supports images and multi-page PDFs. It offers three OCR engines: Engine 2 is the default, while Engine 3 supports handwriting, tables, and more than 200 languages. An `isTable` option is recommended for receipts, invoices, and other table-structured documents. The free plan is free, with 25,000 monthly requests and a searchable-PDF watermark; Engine 3 has an additional 2,500 conversions, but cannot produce searchable PDFs. PRO costs $30 a month, PRO PDF costs $60 a month, and Enterprise starts at $999 a month. OCR.space Local runs offline in self-hosted environments; its license price is available from sales.
