RotationAngle | integer | - | 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, |
LineGroupingMode | string | None | Controls line grouping in PDF text extraction.

DetectNewColumnBySpacesRatio | string | 1.2 | Controls 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, |
AutoAlignColumnsToHeader | boolean | true | Controls 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, |
OCRImagePreprocessingFilters.AddGammaCorrection() | array[string (float format)] | ["1.4"] | Adds a gamma correction filter to the image preprocessing pipeline used during OCR (Optical Character Recognition). This filter adjusts the brightness and contrast of an image by applying a non-linear gamma correction to improve text recognition quality. | 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, |
OCRImagePreprocessingFilters.AddGrayscale() | boolean | false | Set to true to preprocessing filter that converts a colored document/image to grayscale before performing OCR | 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, |
RenderTextObjects | boolean | true | Controls 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, |
RenderImageObjects | boolean | true | Render image objects or not | PDF to JPG, PDF to PNG, PDF to WEBP, |
RenderVectorObjects | boolean | true | Render vector objects or not | PDF to JPG, PDF to PNG, PDF to WEBP, |

RenderingResolution | integer | 120 | See Set Image Resolution for more information. | PDF to JPG, PDF to PNG, PDF to WEBP, PDF to TIFF, |
OptimizeImages | boolean | true | Some 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, |
OutputPageWidth | integer | 1024 | Control 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, |

ConsiderFontSizes | boolean | false | Set 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, |
ExtractionArea | array[number] | - | Extract text in a specific area by defining the extraction area - set with points in the format [x, y, width, height] . | PDF to CSV, PDF to JSON, PDF to XLS, PDF to XML, |
ExtractShadowLikeText | boolean | true | Controls whether to extract invisible text from a PDF document. Set to false to skip over invisible text during extraction. 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, |
