Cloud Native
Zero-Transfer Pipelines
Process files without burdening your application. Gotenberg can stream documents directly from your Cloud Storage (S3, MinIO, GCS) and upload the resulting PDF back to it, bypassing your API entirely.
Direct FetchGotenberg pulls the file directly from an S3 Presigned GET URL.
Auto UploadGotenberg pushes the result to an S3 Presigned PUT URL.
EfficiencySave bandwidth. Your server orchestrates; Gotenberg does the heavy lifting.
curl \
--request POST http://localhost:3000/forms/libreoffice/convert \
# 1. Tell Gotenberg where to fetch the input file (S3 GET) \
--form 'downloadFrom=[{ \
"url": "https://my-bucket.s3.amazonaws.com/file.docx?Start=..." \
}]'
# 2. Tell Gotenberg where to upload the result (S3 PUT) \
--header 'Gotenberg-Webhook-Url: https://my-bucket.s3.amazonaws.com/out.pdf?Start=...' \
--header 'Gotenberg-Webhook-Method: PUT'
