Cloud Storage

PolyDoc can upload generated PDFs and screenshots directly to your cloud storage bucket. The integration is provider-agnostic: you generate a presigned PUT URL from your storage provider, include it in the API request, and PolyDoc uploads the file for you. No credentials are shared — the presigned URL grants temporary, scoped write access to a single object. You can also receive generated files directly in the API response when you omit cloudStorage.

Privacy-first delivery

PolyDoc does not sell hosted object storage for your conversion outputs. We are strict about privacy and security: conversion content is not kept as a long-lived archive on our side. When you use cloud delivery, you supply a presigned PUT URL pointing at your bucket or account — so files end up in infrastructure you already control.

How it works

Works with any storage provider that supports presigned PUT URLs — AWS S3, Google Cloud Storage, Azure Blob Storage, and S3-compatible services are just a few examples.

Generate a presigned PUT URL from your storage provider
Pass it as cloudStorage.presignedUrl in the PolyDoc API request
PolyDoc converts the document and uploads it to the URL via HTTP PUT
The response returns the permanent object URL (without the query string)

{
  "source": "<html>...</html>",
  "cloudStorage": {
    "presignedUrl": "https://my-bucket.s3.amazonaws.com/invoices/inv-001.pdf?X-Amz-..."
  }
}
