# Keep image pixel data as-is (no resample) and just wrap per page
magick image1.jpg image2.jpg -compress jpeg -quality 85 out.pdf

# Mixed orientations? Set per-image page size or rotate first:
magick img-land.jpg -rotate 90 img-port.jpg -compress jpeg -quality 85 out.pdf

Keep order, size, and orientation correct

Follow these tips to Convert Images to PDF that look right the first time:

  • Order: Images combine in the order you select. For predictable order, rename with leading numbers (001‑, 002‑…): Batch Rename.
  • Page size: Choose Letter/A4 (or larger) to avoid heavy downscales; use “Scale” or “Fit” judiciously to prevent cropping.
  • Orientation: Rotate images beforehand so each page orientation is correct. Most print dialogs don’t auto‑rotate mixed sets perfectly.
  • File size: Large PDFs? Use JPEG‑compressed pages (ImageMagick), smaller paper sizes, or run a pass with: Compress PDF.

Common workflows (copy these)

These quick recipes Convert Images to PDF with minimal fuss:

  • Receipts → single PDF (Windows): Drop photos in a folder → rename 001‑, 002‑… → select all → Print → Microsoft Print to PDF → Full page → Save.
  • Notes → tidy PDF (Mac): Preview → reorder thumbnails → Print → Save as PDF → then reorder/merge if needed.
  • iPhone scans → PDF: Notes app → new note → Camera → Scan Documents → Save → Share → Save to Files (PDF).

Troubleshooting (real fixes)

If you Convert Images to PDF and hit snags, try these:

  • Pages out of order after export.
    Sorting changed during selection. Rename with 001‑, 002‑… and select all again, or reorder in Preview (Mac) before saving.
  • PDF is huge.
    Use a smaller paper size, enable JPEG compression (CLI), or run a compression pass: Compress PDF. Photos at 300 DPI are usually enough.
  • Some pages are sideways.
    Rotate images first (Photos/Preview/Photos app) or split landscapes/portraits into separate PDFs, then merge.
  • Quality looks blurry after printing to PDF.
    Disable “Fit picture to frame” (Windows) or increase Scale. For text scans, shoot sharper images or use 300 DPI scans; consider OCR: Extract Text from Images (OCR).
  • Can’t select text in the resulting PDF.
    Image PDFs are pictures of text. Run OCR to make it searchable: OCR guide.
