The JPG format

The photo format par excellence. It compresses the image by discarding details the eye barely notices, so a 12-megapixel photo weighs only a few megabytes. Any device can open it, from an old phone to a photo lab’s printer.

Questions about the JPG format

How do I open a JPG file?

Usually a double click is enough: operating systems and the most common programs recognise it. If the program or website you use won’t accept it, you can convert it here to a more common format, for example PNG.

What extension do JPG files have?

.jpg, .jpeg, .jfif, .jpe. The MIME type is image/jpeg.

Does converting a JPG lose quality?

It depends on the target format: to lossless formats (PNG, FLAC, WAV) nothing is lost; to compressed formats (JPG, MP3, MP4) you can choose the quality to balance size and result.
