Frequently Asked Questions

Are JPG and JPEG the same?+
Yes. JPG and JPEG are the same image format—“.jpg” is just a shorter file extension that became common because older systems preferred 3-letter extensions.
Are JPG or PNG higher quality?+
It depends on the image. PNG is lossless (great for logos, text, UI, and sharp edges). JPG is lossy (usually better for photos at smaller file sizes). For “pure quality,” PNG preserves more detail, but it’s often much larger.
Can JPG be a video?+
No. JPG (JPEG) is an image format, not a video format. A “JPG video” is usually a misunderstanding, or a slideshow/video file using JPG frames.
Can JPG be transparent?+
No—JPG doesn’t support transparency (no alpha channel). If you need transparency, use PNG or WebP.
Can JPG files have viruses?+
The JPG format itself isn’t a virus, but any download can be risky if it comes from an untrusted source. Stick to reputable sites and scan anything suspicious.
