PDF4ME

Comprehensive PDF processing API with 60+ operations: convert, merge, split, compress, OCR, watermark, form filling, digital signatures, and more.

Official docs: https://dev.pdf4me.com/apiv2/documentation/

When to Use

Use this skill when you need to:

Convert documents to/from PDF (Word, Excel, PowerPoint, HTML, images) Merge multiple PDFs into one Split PDF into multiple files Compress PDF to reduce file size Add watermarks, stamps, page numbers Extract text, tables, or images from PDF Fill PDF forms programmatically OCR scanned documents Protect/unlock PDF with password Create barcodes and QR codes Prerequisites Create an account at https://dev.pdf4me.com/ Get your API key from https://dev.pdf4me.com/dashboard/#/api-keys/

Set environment variable:

export PDF4ME_API_KEY="your-api-key-here"

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 -c 'curl -s "https://api.example.com" -H "Authorization: Bearer $API_KEY"'

How to Use 1. Convert to PDF

Convert Word, Excel, PowerPoint, images to PDF:

Convert a text file to PDF

echo "Hello, PDF4ME!" > /tmp/test.txt BASE64_CONTENT=$(base64 < /tmp/test.txt)

Write to /tmp/pdf4me_request.json:

{ "docContent": "${BASE64_CONTENT}", "docName": "test.txt" }

Then run:

bash -c 'curl -s -X POST "https://api.pdf4me.com/api/v2/ConvertToPdf" --header "Authorization: ${PDF4ME_API_KEY}" --header "Content-Type: application/json" -d @/tmp/pdf4me_request.json' | jq -r '.docContent' | base64 -d > /tmp/output.pdf

  1. HTML to PDF

Convert HTML content to PDF:

HTML_CONTENT=$(echo '<html><body>

Hello World

This is a test.

</body></html>' | base64)

Write to /tmp/pdf4me_request.json:

{ "docContent": "${HTML_CONTENT}", "docName": "test.html", "layout": "Portrait", "format": "A4" }

  1. Merge PDFs

Combine multiple PDFs into one:

PDF1_BASE64=$(base64 < file1.pdf) PDF2_BASE64=$(base64 < file2.pdf)

Write to /tmp/pdf4me_request.json:

{ "docContent": ["${PDF1_BASE64}", "${PDF2_BASE64}"], "docName": "merged.pdf" }

Then run:

bash -c 'curl -s -X POST "https://api.pdf4me.com/api/v2/Merge" --header "Authorization: ${PDF4ME_API_KEY}" --header "Content-Type: application/json" -d @/tmp/pdf4me_request.json' | jq -r '.docContent' | base64 -d > merged.pdf
