# PDF.co

All-in-one PDF processing API. Convert, extract, merge, split, compress PDFs and more. Supports OCR for scanned documents.

> Official docs: https://docs.pdf.co/

---

## When to Use

Use this skill when you need to:

- Extract text from PDF files (with OCR support)
- Convert PDF to CSV, JSON, or other formats
- Merge multiple PDFs into one
- Split PDF into multiple files
- Compress PDF to reduce file size
- Convert HTML/URL to PDF
- Parse invoices and documents with AI

---

## Prerequisites

1. Create an account at https://pdf.co/
2. Get your API key from https://app.pdf.co/

Set environment variable:

```bash
export PDFCO_API_KEY="[email protected]_your-api-key"
```

---


> **Important:** When using `$VAR` in a command that pipes to another command, wrap the command containing `$VAR` in `bash -c '...'`. Due to a Claude Code bug, environment variables are silently cleared when pipes are used directly.
> ```bash
> bash -c 'curl -s "https://api.example.com" -H "Authorization: Bearer $API_KEY"'
> ```

## How to Use

### 1. PDF to Text

Extract text from PDF with OCR support:

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-to-text/sample.pdf",
  "inline": true
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/convert/to/text" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

**With specific pages (1-indexed):**

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-to-text/sample.pdf",
  "pages": "1-3",
  "inline": true
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/convert/to/text" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 2. PDF to CSV

Convert PDF tables to CSV:

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-to-csv/sample.pdf",
  "inline": true
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/convert/to/csv" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 3. Merge PDFs

Combine multiple PDFs into one:

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-merge/sample1.pdf,https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-merge/sample2.pdf",
  "name": "merged.pdf"
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/merge" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 4. Split PDF

Split PDF by page ranges:

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-split/sample.pdf",
  "pages": "1-2,3-"
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/split" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 5. Compress PDF

Reduce PDF file size:

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/pdf-optimize/sample.pdf",
  "name": "compressed.pdf"
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/optimize" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 6. HTML to PDF

Convert HTML or URL to PDF:

Write to `/tmp/request.json`:

```json
{
  "html": "<h1>Hello World</h1><p>This is a test.</p>",
  "name": "output.pdf"
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/convert/from/html" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

**From URL:**

Write to `/tmp/request.json`:

```json
{
  "url": "https://example.com",
  "name": "webpage.pdf"
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/convert/from/url" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 7. AI Invoice Parser

Extract structured data from invoices:

Write to `/tmp/request.json`:

```json
{
  "url": "https://pdfco-test-files.s3.us-west-2.amazonaws.com/ai-invoice-parser/sample-invoice.pdf",
  "inline": true
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/ai-invoice-parser" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 8. Upload Local File

Upload a local file first, then use the returned URL:

**Step 1: Get presigned upload URL**

```bash
bash -c 'curl -s "https://api.pdf.co/v1/file/upload/get-presigned-url?name=myfile.pdf&contenttype=application/pdf" --header "x-api-key: ${PDFCO_API_KEY}"' | jq -r '.presignedUrl, .url'
```

Copy the presigned URL and file URL from the response.

**Step 2: Upload file**

Replace `<presigned-url>` with the URL from Step 1:

```bash
curl -X PUT "<presigned-url>" --header "Content-Type: application/pdf" --data-binary @/path/to/your/file.pdf
```

**Step 3: Use file URL in subsequent API calls**

Replace `<file-url>` with the file URL from Step 1:

Write to `/tmp/request.json`:

```json
{
  "url": "<file-url>",
  "inline": true
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/pdf/convert/to/text" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```

### 9. Async Mode (Large Files)

For large files, use async mode to avoid timeouts:

**Step 1: Start async job**

Write to `/tmp/request.json`:

```json
{
  "url": "https://example.com/large-file.pdf",
  "async": true
}
```

```bash
bash -c 'curl -s --location --request POST "https://api.pdf.co/v1/pdf/convert/to/text" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json' | jq -r '.jobId'
```

Copy the job ID from the response.

**Step 2: Check job status**

Replace `<job-id>` with the job ID from Step 1:

Write to `/tmp/request.json`:

```json
{
  "jobid": "<job-id>"
}
```

```bash
bash -c 'curl --location --request POST "https://api.pdf.co/v1/job/check" --header "x-api-key: ${PDFCO_API_KEY}" --header "Content-Type: application/json" -d @/tmp/request.json'
```
