The rate limits per time are lenient to spikes caused by individual documents with page counts greater than the limit. They are triggered only as soon as the rate limit had been exceeded by the previous request.

File Limits#


Files uploaded to the processing endpoint are currently limited to 100 MB.

Supported Types#

  • Image formats: JPEG, PNG, GIF, TIFF
  • Document formats: PDF

Uploaded images should have a sufficient resolution to support good extraction results. Conversely, lower resolutions lead to faster upload times. We recommend 220 dpi, which makes dimensions of 2600x1800 pixels for an A4 document.
