JPG vs JPEG
JPG and JPEG usually mean the same image format. The shorter .jpg extension became common because older systems used three-letter file extensions.
Quick answer
For normal PDF workflows, JPG and JPEG are the same practical format. LiftPDF's JPG to PDF tool accepts both image/jpeg file types.
Why two names exist
JPEG is the format name from the Joint Photographic Experts Group. JPG is the common three-letter file extension used by many operating systems and apps.
In everyday use, .jpg and .jpeg files are treated the same by browsers, photo apps and PDF converters.
When converting to PDF
Use the same quality rules for both: start with the original file, avoid repeated resaving, and choose PDF layout settings that do not unnecessarily enlarge the image.
FAQ
Common questions
Should I rename JPEG to JPG?
Usually no. Modern tools handle both extensions. Renaming alone does not improve quality.
Does JPG or JPEG create a better PDF?
Neither is inherently better. Source resolution and compression quality matter more.
