Form processing model requirements and limitations

Languages supported

Currently form processing works with documents in English.


Form processing works on input documents that meet the following requirements:

  • JPG, PNG, or PDF format (text or scanned). Text-embedded PDFs are better, because there won't be any errors in character extraction and location.
  • If your PDFs are password-locked, you must remove the lock before submitting them.
  • The combined file size of the documents used for training per collection must not exceed 50 MB, and PDF documents shouldn't have more than 500 pages.
  • For images, dimensions must be between 50 × 50 and 10,000 × 10,000 pixels.
  • For PDF files, dimensions must be at most 17 x 17 inches, corresponding to Legal or A3 paper sizes and smaller.
  • If scanned from paper documents, scans should be high-quality images.
  • Must use the Latin alphabet (English characters).


AI Builder doesn't currently support the following types of form processing input data:

  • Check boxes or radio buttons
  • Signatures
  • Fillable PDFs
