Workflow: Add images → (optional) reorder → choose paper/fit/margins/quality → Create PDF.
Paper Size: Auto adapts the page to your image's aspect (limited to a reasonable size). A4/Letter use fixed page boxes.
Fit Modes:
- Contain - fits whole image inside margins (may leave whitespace).
- Cover - fills page; parts may be clipped.
- Scale 1:1 - places the image at native pixel size (1 px ≈ 1 pt) inside margins.
Margins: points (pt). 72 pt = 1 inch.
JPEG quality: PNGs are converted to JPEG for compact PDFs. 0.85-0.90 is a good balance.
Privacy: 100% in-browser. Files never leave your device.
Tip: Large images can create very large PDFs. Consider margins ≥10pt for printers to avoid clipping.

Technical note: The PDF is assembled client-side: each image becomes a page with a single /XObject (DCT-encoded JPEG). Coordinates are in points (1/72"). XRef offsets and streams are computed precisely to produce a valid PDF 1.4 file.
