PDF Tools
PDF to JSON Java Overview
Convert PDF documents into clean, structured JSON built for large language models, retrieval-augmented generation, and automated data pipelines. Every page is decomposed into typed elements - paragraphs, tables, images, and graphics - each carrying its text, reading order, and precise bounding box. Tables are reconstructed into rows and cells so tabular data stays machine-readable for downstream use. Handle password-protected files, target page ranges, and apply OCR to scanned documents so even image-based PDFs yield searchable, structured output for indexing, analytics, and AI ingestion.

File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected documents.
PageRange
String Default: 1-2000Set page range. Example 1-10 or 1,2,5.
OcrMode
Collection Default: autoDefines how OCR is applied during conversion. Auto performs OCR only when needed. Force applies OCR to all pages. Never disables OCR entirely.
OcrLanguage
Collection Default: autoConfigure the OCR language for text recognition. If auto-detection fails, manually specify the language.
Values: auto ar ca zh da nl en fi fr de el ko it ja no pl pt ro ru sl es sv tr ua thIncludeGraphics
Bool Default: TrueInclude vector graphic elements in the JSON output.
ExtractTableRows
Bool Default: TrueReconstruct table rows and cells from the detected table layout.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
