Why Convert JPG to PDF?
PDF is the universal document format. Converting photos to PDF makes them easy to email (one file vs many), print with consistent sizing, combine into collections, and archive with metadata. Many government forms and applications require PDF submissions.
How to Convert JPG to PDF
Upload one or more JPG files.
KoalaPic embeds each image in a PDF. For multiple files, enable 'Merge' for a single multi-page PDF.
Download your PDF, ready to share, print, or submit.
Quality Note
The JPG is embedded directly in the PDF — no re-compression occurs. The PDF file size is roughly equal to the JPG(s) plus a small overhead for PDF structure.
