POST /v1/pdf/convert/to/text

Auto classification Of incoming documents: Use the Document Classifier endpoint to automatically sort/detect the class of the document based on keywords-based rules. For example, you can define rules to find which vendor provided the document to find which template to apply accordingly.

Attributes

Attributes are case-sensitive and should be inside JSON for POST request. for example: { "url": "https://example.com/file1.pdf" }

Attribute	Type	Required	Default	Description
url	string	Yes	-	URL to the source file url attribute
callback	string	No	-	The callback URL (or Webhook) used to receive the POST data. see Webhooks & Callbacks. This is only applicable when async is set to true.
httpusername	string	No	-	HTTP auth user name if required to access source URL.
httppassword	string	No	-	HTTP auth password if required to access source URL.
pages	string	No	all pages	Specify page indices as comma-separated values or ranges to process (e.g. “0, 1, 2-” or “1, 2, 3-7”). The first-page index is 0. Use ”!” before a number for inverted page numbers (e.g. “!0” for the last page). If not specified, the default configuration processes all pages. The input must be in string format.
unwrap	boolean	No	false	Unwrap lines into a single line within table cells in provided PDF documents. This is only applicable when lineGrouping is set to 1.
rect	string	No	-	Defines coordinates for extraction. UsePDF Edit Add Helperto get or measure PDF coordinates. The format is {x} {y} {width} {height}.
lang	string	No	eng	Set the language for OCR (text from image) to use for scanned PDF, PNG, and JPG documents input when extracting text. see Language Support. You can also use 2 languages simultaneously like this: eng+deu (any combination).
inline	boolean	No	false	Set to true to return results inside the response. Otherwise, the endpoint will return a URL to the output file generated.
lineGrouping	string	No	-	Controls how lines of text are grouped when extracting data from a PDF. Line grouping within table cells. The available modes are: 1, 2, 3. For more information, see Line Grouping.
password	string	No	-	Password for the PDF file.
async	boolean	No	false	Set async to true for long processes to run in the background, API will then return a jobId which you can use with the Background Job Check endpoint. Also see Webhooks & Callbacks
name	string	No	-	File name for the generated output, the input must be in string format.
expiration	integer	No	60	Set the expiration time for the output link in minutes. After this specified duration, any generated output file(s) will be automatically deleted from PDF.co Temporary Files Storage. The maximum duration for link expiration varies based on your current subscription plan. To store permanent input files (e.g. re-usable images, pdf templates, documents) consider using PDF.co Built-In Files Storage.
profiles	object	No	-	See Profiles for more information.
OCRMode	string	No	Auto	Specifies 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.
OCRResolution	integer	No	300	Use this parameter to change the OCR resolution from the default 300 dpi. The range is from 72 to 1200 dpi.
RotationAngle	integer	No	-	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.
LineGroupingMode	string	No	None	Controls 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).
ConsiderFontColors	boolean	No	false	Controls whether font colors should be considered when detecting table structure and merging text objects during PDF extraction. Set to true to consider font colors.
DetectNewColumnBySpacesRatio	string	No	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.
AutoAlignColumnsToHeader	boolean	No	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.
OCRImagePreprocessingFilters	object	No	-	Image preprocessing filters for OCR. Refer to OCRImagePreprocessingFilters for usage examples.
.AddGrayscale	boolean	No	false	Converts to grayscale before OCR.
.AddGammaCorrection	array[string (float format)]	No	[“1.4”]	Adds a gamma correction filter.
OCRAutoModeMinExistingTextLength	integer	No	8	The minimum number of characters a page must have to skip OCR. If a page has fewer, OCR will run. For example, if set to 8, OCR is skipped on pages with more than 8 characters.
DataEncryptionAlgorithm	string	No	-	Controls the encryption algorithm used for data encryption. See User-Controlled Encryption for more information. The available algorithms are: AES128, AES192, AES256.
DataEncryptionKey	string	No	-	Controls the encryption key used for data encryption. See User-Controlled Encryption for more information.
DataEncryptionIV	string	No	-	Controls the encryption IV used for data encryption. See User-Controlled Encryption for more information.
DataDecryptionAlgorithm	string	No	-	Controls the decryption algorithm used for data decryption. See User-Controlled Encryption for more information. The available algorithms are: AES128, AES192, AES256.
DataDecryptionKey	string	No	-	Controls the decryption key used for data decryption. See User-Controlled Encryption for more information.
DataDecryptionIV	string	No	-	Controls the decryption IV used for data decryption. See User-Controlled Encryption for more information.

Line Grouping Options

• "1": GroupByRows – Each row is checked against the next row to see if they can be grouped together. Rows will only be grouped if all cells in the current row can be grouped with all cells in the next row. Useful when merging related content that spans multiple lines but belongs to the same logical row.
• "2": GroupByColumns – Each cell is checked against the cell below it in the next row to determine if they can be grouped. Cells are grouped within the same column even if others can’t be grouped. Useful for columnar data where content in each column might span multiple lines.
• "3": JoinOrphanedRows – Joins a row with a single cell to the previous row if there is no separator between them. Useful for handling cases with orphaned or misaligned content.

OCRImagePreprocessingFilters

To set image preprocessing filters, please use:

{
 "profiles": "{
    "OCRImagePreprocessingFilters.AddGrayscale()": [],
    "OCRImagePreprocessingFilters.AddGammaCorrection()": [
        1.4
    ]
}"
}

Inconsistent URL Encoding in cURL Output: When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (&) may appear as \u0026 in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you’re parsing the response programmatically, your JSON parser will handle this conversion automatically.
