# File to PDF (PDF123)

Convert an Office document into a PDF using LibreOffice.

Web version: https://pdf123.xyz/file-to-pdf · All tools: https://pdf123.xyz/skills/pdf123.md

## When to use

- Turn a DOCX letter into a PDF for a portal that only takes PDF
- Print a spreadsheet to PDF when you accept LibreOffice pagination
- Convert ODT that was never opened in Word

## Run it

Replace the sample file names and values with the user's, then run:

```bash
API="${PDFX_API_BASE:-https://pdf123.xyz}"
curl -sS --fail-with-body -X POST "$API/api/v1/convert/file/pdf" \
  -F "fileInput=@input.docx" \
  --output-dir "pdf123-output/$(date +%Y%m%d-%H%M%S)" --create-dirs -OJ -w '%{filename_effective} %{content_type}\n'
```

## Inputs

Everything is `multipart/form-data`. The command above already sends each field with its default; keep them all and change only the values the user asked for, since some endpoints reject a missing optional field.

| Field | Type | Required | Default | Notes |
| --- | --- | --- | --- | --- |
| `fileInput` | file | yes | | .docx, .doc, .odt, .rtf, .xlsx, .xls, .ods, .pptx, .ppt, .odp, .txt (one file) |

## Result

curl saves the result in a new `pdf123-output/<timestamp>/` directory under the server's file name and prints its path and content type. Several output files come back as one ZIP. Tell the user where the file is.

## Limits

- Only formats soffice imports
- No print-area or paper-size fields
- Macros and encryption in the office file often fail
- Upload limit on this website: 500 MB per file, sent in chunks above about 95 MB. A single direct API request body is capped at 100 MB.

## Errors

- A non-zero curl exit means the request failed. The saved file then holds `application/problem+json`; read it and report its `detail` to the user instead of retrying blindly.
- `413`: the upload exceeds 100 MiB. `429`: wait for `Retry-After` seconds, then retry once.
- Send `X-API-KEY: $PDFX_API_KEY` only if the user has a PDF123 API key; anonymous calls work without it.

## Privacy

Files are uploaded to the API host, processed, and deleted once the response is sent. For confidential files, ask before uploading, or use a self-hosted server via `PDFX_API_BASE`.
