What is JPG?
JPG (JPEG) is the standard format for photos. Its lossy compression makes images much smaller with little visible difference, and every device, browser and program opens it. It does not support transparency, and repeated re-saving gradually degrades quality.
What is JPEG?
JPEG is the same format as JPG — only the file extension differs. It is the standard for photos, with lossy compression that keeps files small and universal support, but no transparency.
Tips for converting JPG to JPEG
- Transparent backgrounds are only kept in formats that support them (PNG, WebP, AVIF); JPG fills them with white.
- For photos, lossy formats keep files small; for logos, screenshots and text, lossless PNG stays sharper.
- Converting an already compressed JPG does not add detail — start from the highest-quality original you have.
- If the image is for a website, a modern format such as WebP or AVIF usually loads faster than JPEG.
