How to import document data and sample import formats.
Specifications
Format: PDF
Recommended size: 100 pages or fewer
Import methods:
- IAM Delegated Access
- Signed URLs (
httpsURLs only)
When importing document data to Labelbox, you are no longer required to provide an OCR extract in the form of a JSON file. Labelbox generates text layers automatically during PDF import using Google Document AI if the data row doesn't include a text layer. The JSON file generated will be your text layer, rendered on top of your PDF in the Document Editor.
Note: Previously generated PDF documents without text layers will not be retroactively filled with the text layer generated by Labelbox.
Google Document AI has the following limitations:
- The document must have no more than 15 pages
- The file size should not exceed 20 MB.
Additionally, Google Document AI optimizes documents before OCR processing. This optimization might include rotating images or pages to ensure text appears horizontally. Consequently, token coordinates are calculated based on the rotated/optimized images, resulting in potential discrepancies with the original PDF document.
For example, the document is rotated 90 degrees before processing in a landscape-oriented PDF. As a result, all tokens in the text layer are also rotated by 90 degrees.
Text Layer Validation Schema
If you want to upload your own text layer, the textLayer JSON file must adhere to the following JSON schema.

Verify files are processed
File processing can take up to 20 mins
Since PDFs and OCR'ed files can be very large, the conversion can sometimes take up to 20 minutes to perform a data upload.
By checking the Media Attributes section, you can verify whether a file conversion using a custom or Labelbox-generated text layer is complete.
- If
Is text layer valid = true, the file was successfully processed.
