PDF exports

PDF is the right format when people need to print, archive, or e-sign. ScreenNabster uses the browser's print pipeline so CSS @media print rules apply the same way they would for a visitor choosing “Print to PDF.”

Overview

Request output: "pdf". The worker loads your URL or HTML, applies viewport and interaction options, then emits a binary PDF stream back through the gateway. Large documents may take longer than a PNG—plan timeouts accordingly or switch to background jobs.

Minimal example

curl

curl -X POST "https://screennabster.com/api/v1/capture" \
  -H "X-API-Key: pk_live_…" \
  -H "Content-Type: application/json" \
  -d "{\"url\":\"https://example.com/invoice\",\"output\":\"pdf\"}" \
  --output invoice.pdf

Paper size & orientation

pdf_format accepts A4 (default), A3, Letter, Legal, or Tabloid. Set pdf_landscape: true when charts or tables need horizontal room.

body.json

{
  "url": "https://example.com/report",
  "output": "pdf",
  "pdf_format": "Letter",
  "pdf_landscape": true
}

Margins & scale

Provide pdf_margin as a CSS shorthand (e.g. "1in") or set individual sides with pdf_margin_top, pdf_margin_right, pdf_margin_bottom, pdf_margin_left. Use pdf_scale between 0.1 and 2 to shrink or enlarge content when the default print density is too large for archival policies.

Background graphics

By default pdf_print_background: true keeps gradients and hero images. Set it to false for ink-saving documents where only text matters.

When PDF beats PNG

Text stays selectable and searchable inside the file.
Multi-page articles become one artifact instead of a huge bitmap.
Branded templates with print CSS can omit chrome you do not want in screenshots.

When you need pixel-perfect marketing thumbnails, PNG or WebP from the viewport guide is usually simpler.
