When you snap a passport, contract or receipt on your phone, the choice between sending it as a JPG or a PDF matters more than people think.
Here is the honest answer.
Where JPG wins
Smaller files for single pages. Universal — every app and OS opens them without thinking. Great for quick share-with-a-friend cases.
Where PDF wins
Multiple pages in one file. Searchable text if OCR is applied. Professional standard for legal, financial and HR documents. Most submission portals demand PDFs, not photos.
Quality compared
Both can be lossy or near-lossless. A high-quality JPG and a PDF made from that JPG are visually identical. The PDF adds structure (multiple pages, search) but no quality.
Best for…
JPG for casual single-page photos to friends. PDF for anything official or multi-page. Convert-image-to-pdf does the switch in seconds.
FAQ
Will the JPG fit in a PDF?
Yes — JPGs embed into PDFs without quality loss.
Why do portals demand PDFs?
PDFs combine pages, support signatures and are tamper-evident. Photos are easier to crop suspiciously.
Can I combine multiple photos into one PDF?
Yes — convert-image-to-pdf handles batches and orders them.
