What is a JPEG file?

JPEG (Joint Photographic Experts Group) is the most widely used image format for photographs and complex images. It uses lossy compression to reduce file size while maintaining acceptable visual quality, making it ideal for web use, photography, and sharing images online.

Is there a difference between JPEG and JPG?

No, JPEG and JPG are exactly the same format. The only difference is the file extension. JPG became common because older Windows versions required three-letter extensions. Both .jpeg and .jpg files are identical in format and quality.

How does JPEG compression affect quality?

JPEG uses lossy compression, meaning some image data is discarded to reduce file size. Higher quality settings preserve more detail but create larger files. For web use, 70-80% quality offers a good balance. For archiving, use higher quality or consider PNG format.

Does JPEG support transparent backgrounds?

No, JPEG does not support transparency. If your image has a transparent background, it will be replaced with a solid color (usually white) when converting to JPEG. For images that need transparency, use PNG or WebP format instead.

What is EXIF data in JPEG photos?

EXIF (Exchangeable Image File Format) data is metadata stored in JPEG files by cameras and phones. It includes information like date taken, camera model, exposure settings, and GPS location. Our converter can preserve or remove EXIF data based on your privacy preferences.

Is JPEG the best format for photos?

JPEG is excellent for photographs due to its efficient compression and universal support. For web sharing and everyday use, JPEG is ideal. For professional editing, consider RAW or TIFF. For web with better compression, try WebP. PNG is better for graphics with text or sharp edges.

Can I resize images during conversion?
