Get PDF Information & Form Fields

Extract information from a PDF document, including form fields, page count, size, author, description, keywords, and more.

Input

Name	Description	Required
PDF URL	Provide the URL to the source PDF document, or a filetoken:// link from PDF.co Built-In Files Storage. If you use another cloud service such as Google Drive or Dropbox ensure the link is publicly accessible.	Yes
Extract Fillable Fields	Enable this option to extract information from fillable form fields in the PDF.	No
File Name	File name for the generated output, the input must be in string format.	No
Webhook URL	The callback URL or Webhook used to receive the output data.	No
Output Links Expiration (In Minutes)	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.	No
HTTP Username	HTTP auth user name if required to access source URL.	No
HTTP Password	HTTP auth password if required to access source URL.	No
Custom Profiles	Use JSON to customize PDF processing with options like output resolution, OCR settings, text extraction methods, encryption, and image handling. Check our Custom Profiles section to see all available parameters for your current endpoint.	No

Custom Profiles

You can set additional options for the operation used in the PDF.co node by using Custom Profiles. A custom profile is a string in JSON-like format containing predefined parameters.

Here’s an example of a Custom Profiles input:

{'OCRMode': 'TextFromImagesAndVectorsAndRepairedFonts'}

With this input, the PDF.co operation will extract text from images and repaired fonts from documents. You can find the list of available parameters for customizing profiles in the PDF.co operation documentation below:

You can use any regular API parameter from the API Reference within n8n 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.

Parameter	Type	Default	Description
OCRMode	string	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	300	Use this parameter to change the OCR resolution from the default 300 dpi. The range is from 72 to 1200 dpi.
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.
LineGroupingMode	string	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	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	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	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	-	Image preprocessing filters for OCR. Use methods like AddGammaCorrection() and AddGrayscale() by including them as JSON keys. See sample usage.
.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.
.AddGrayscale()	boolean	false	Set to true to preprocessing filter that converts a colored document/image to grayscale before performing OCR.
DataEncryptionAlgorithm	string	-	Controls the encryption algorithm used for data encryption. See User-Controlled Encryption for more information. The available algorithms are: AES128, AES192, AES256.
DataEncryptionKey	string	-	Controls the encryption key used for data encryption. See User-Controlled Encryption for more information.
DataEncryptionIV	string	-	Controls the encryption IV used for data encryption. See User-Controlled Encryption for more information.
DataDecryptionAlgorithm	string	-	Controls the decryption algorithm used for data decryption. See User-Controlled Encryption for more information. The available algorithms are: AES128, AES192, AES256.
DataDecryptionKey	string	-	Controls the decryption key used for data decryption. See User-Controlled Encryption for more information.
DataDecryptionIV	string	-	Controls the decryption IV used for data decryption. See User-Controlled Encryption for more information.
