Sample JSON

{ "ImageOptimizationFormat": "JPEG", "JPEGQuality": 25, "ResampleImages": true, "ResamplingResolution": 120, "GrayscaleImages": true }
You can use any regular API parameter from the API Reference within Zapier using the std_params feature in profiles. The std_params enables the definition of regular API parameters in a JSON format, See Standard Parameters for detailed documentation and examples.
ParameterTypeDefaultDescriptionAvailable for
outputDataFormatstring-If you require your output as base64 format, set this to base64PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
ColumnDetectionModestringContent Groups And BordersControls column detection/alignment in PDF table extraction. See Column Detection Mode for more information.PDF to CSV, PDF to XLS
OCRModestringAutoSpecifies how OCR (Optical Character Recognition) should process input content, offering various modes to tailor text extraction based on content type such as images, fonts, and vector graphics. For more information, see OCR Extraction Modes.PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
OCRResolutioninteger300Use this parameter to change the OCR resolution from the default 300 dpi. The range is from 72 to 1200 dpi.PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
RotationAngleinteger-Use manual rotation to handle PDFs with vertically drawn text. Normally, OCR automatically detects page rotation in PDFs and extracts text accurately. However, in some cases, the PDF might not have an actual rotated page --- Rather, the text itself is drawn vertically. In such scenarios, auto-detection may fail. You can use this parameter to manually set the page rotation. The available angles are: 0, 1, 2, 3.PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
LineGroupingModestringNoneControls line grouping in PDF text extraction. Modes: None (no grouping), GroupByRows (merge rows if all cells align), GroupByColumns (merge cells by column), JoinOrphanedRows (merge single-cell rows to above if no separator).PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
ConsiderFontColorsbooleanfalseControls whether font colors should be considered when detecting table structure and merging text objects during PDF extraction. Set to true to consider font colors.PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
DetectNewColumnBySpacesRatiostring1.2Controls how spaces between words are interpreted for column detection in PDF text extraction. It defines the ratio of space width that determines when text should be treated as being in separate columns.PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
AutoAlignColumnsToHeaderbooleantrueControls how columns are detected and aligned during table extraction from PDF documents. It affects both table structure detection and text extraction with formatting preservation. Set to true to automatically align columns to the header row. When set to true (default), the row with the most columns is used as the header, and all other rows are aligned to this structure --- ideal for well-structured tables. When set to false, columns are analyzed independently across all rows to build the structure, which works better for inconsistent or irregular tables.PDF to CSV, PDF to JSON, PDF to Text, PDF to XLS, PDF to XML, PDF to HTML, PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF
OCRImagePreprocessingFiltersobject-Image preprocessing filters for OCR. Refer to OCRImagePreprocessingFilters for usage examples.

RenderTextObjectsbooleantrueControls whether to render text objects in the PDF document. When set to true, it will render all text objects in the PDF document. Set to false to skip over text objects during rendering. See Disable Text Layer for more information.PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF

OptimizeImagesbooleantrueSome PDF may have high quality images used in the document and you may need to keep the quality of these images in the output HTML. By default PDF to HTML is optimizing images and you can easily turn it off. See Control Image Quality for more information.PDF to HTML
OutputPageWidthinteger1024Control page width (in pixels) for output HTML. Height is calculated and used according to the original pdf pages ratio. See Control Output Page Width for more information.PDF to HTML

ConsiderFontSizesbooleanfalseSet to true to this parameter makes the converter consider font size differences in document text when detecting and parsing table structures. This can be helpful in cases where tables are formatted using different font sizes to distinguish between headers, data cells, or other structural elements.PDF to CSV, PDF to JSON, PDF to XLS, PDF to XML

This is particularly useful when dealing with PDFs that contain hidden text layers or when you only want to extract visible content. When this value is set to false, OCRMode must be set to Auto to properly apply the shadow text filtering effect.PDF to CSV, PDF to JSON, PDF to XLS, PDF to XML

Column Detection Mode

This might be case when a document contains a number of overlapping invisible text and vector objects that affect column detection. In this case you may need to fix the wrongly positioned data. Set the options for your column detection via the following profiles parameters: ColumnDetectionMode - available values:
  • ContentGroupsAndBorders (default, no need to specify)
  • ContentGroups
  • Borders
  • BorderedTables
  • ContentGroupsAI
