# Upload File via Pre-signed URL

> With this method you can upload files up to 100mb in size. Please note that to process these files you should use async=true mode with data extraction and tools endpoints along with [Job Check](/api-reference/job-check) to check status of background jobs you create.

`PUT {presigned url}`

**Important** The presigned URL must be retreived from the /file/upload/get-presigned-url for the PUT operation to succeed.

Content-Type header
When sending PUT request don't forget to add Content-Type header with proper value based on input file type.

For example:

| File Extension         | Content-Type Value         |
| ---------------------- | -------------------------- |
| `.txt .csv .xml .json` | text/plain                 |
| `.pdf`                 | application/pdf            |
| `.msg .eml`            | application/vnd.ms-outlook |
| `.doc`                 | application/msword         |

If you're not sure then use application/octet-stream header. It works for most file types.

All uploaded files are treated as temporary files and are automatically permanently removed after 1 hour. If you have a file that you want to reuse over and over, please upload it to PDF.co Built-In Files Storage and get its filetoken:// link that you may reuse inside PDF.co API.

<Note>
  **Inconsistent URL Encoding in cURL Output:** When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (`&`) may appear as `\u0026` in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you're parsing the response programmatically, your JSON parser will handle this conversion automatically.
