Why Convert Images to PDF?

Bundle scans and photos

Send one clean PDF instead of a bunch of image attachments.

Preserve order

Once bundled, images stay in order — great for numbered pages, receipts, or exam sheets.

Universal format

Every device, printer, and email client speaks PDF.

Add to a larger doc

Merge the resulting PDF with contracts, invoices, or reports.

💡 Pro Tips

  • Compress first: If your images are huge photos, run them through your OS image tools first — smaller inputs = a smaller final PDF.

  • Use Fit to Image for scans: Fit mode keeps the exact page proportions of the scan — better for document capture.

  • A4 for Europe, Letter for US: Match your printer's paper size to avoid rescaling when printing.

  • Merge PDFs after: Convert images first, then combine with another PDF using the Merge tool.
