What is JPEG? Downscaling of Cb and Cr allows you to reduce file size with almost unnoticeable losses in quality. Quantization after Discrete Cosine Transform DCT allows you to control reduction of image size by rounding coefficients for sharp high-frequency details.
Optional progressive encoding allows you to view a low-quality preview of the whole image after partial decoding of its byte stream. Lossless entropy coding for DCT-transformed and quantized image data. Here are some of its advantages: This format has been in use for quite a long time. It is compatible with most image processing apps.
That makes JPEG format the more suitable one when it comes to transferring images over the web. Due to ringing and blocking artifacts it distorts images with sharp edges, which become harder to recognize.
Only 1 or 3 color channels are supported. It does not offer transparency preservation for images there's no separate alpha-channel. Here are some of the reasons why you might want to use JPEG Has single compression architecture for both lossy and lossless compression One master image replaces multiple derivatives different resolutions and quality Works well for video production and live TV content Works well with natural photos as well as synthetic visual content Resilience to bit errors JPEG also has some disadvantages It is not yet supported by web browsers except Safari JPEG is not compatible with JPEG.
PNG Features PNG has several main features that allowed it to become the most popular lossless format for synthetic raster images. Here are some additional advantages of this format: Wide support by web browsers and other software No patent issues Alpha channel for adjustable transparency of pixels opacity High dynamic range up to 16 bits per channel However, PNG is not perfect, and has its drawbacks too: No built-in support of lossy compression Low compression ratio due to outdated compression algorithm No built-in support of animations only in extensions such as APNG What's better: JPEG vs JPEG vs PNG.
The tool automatically switches between 24bit or 48bit storage dependent on the color depth of the raw image in Photoshop. Let's have a look at it Let's start having a look at the extreme end - at a compression rate of See the left 2 pictures in the image row above as a reference without magnification. Nonetheless it does a much better job than JPEG here. You may notice that the in- famous blocks the 8x8 pixel blocks from the cosine transformation are no longer present in the JPEG image.
