Difference Between JPEG and PNG

If you are searching for differences between JPEG and PNG then keep reading this article. Both JPEG and PNG are the most used and popular image formats. Both have their advantages and disadvantages.

In this article, we will list down the differences between PNG and JPEG compression.

What is JPEG?

JPEG or JPEG compression is a lossy data compression algorithm, designed to reduce the storage space usage of digital image files. The major difference between JPEG and PNG is that JPEG uses a lossy compression algorithm whereas PNG uses a lossless compression algorithm. What is PNG? PNG is a free, open-source image compression format that supports transparency, solid color, outline images and can be saved as JPEG, GIF, BMP, TIFF, TGA, JPEG 2000, and JPEG XR files. How do PNG & JPEG Compress Images? PNG or PNG image files can be decompressed into a normal image file which is the same size as the PNG image file. For example, the image file codice_1 in PNG format is three times larger than the image file codice_2 in the JPEG format.

What is PNG?

PNG stands for Portable Network Graphics. PNG is also known as Simple Network Graphics which is used to store images in PNG files which takes much less storage on a computer. PNG offers quality images in the same sizes as a JPEG but unlike JPEG, the quality remains constant in the same size PNG file. As the main feature, both of these formats are image file formats. However, they differ in certain features like compression algorithm, color depth and media type support. PNG vs JPEG – Compression Algorithm JPEG used a lossy compression algorithm. An image may get data loss when it is scaled or viewed larger. Therefore, the JPEG compression algorithm produces lossy image files. PNG uses a lossless compression algorithm which means that the image size stays the same in each PNG file.

What are the differences between JPEG and PNG?

JPEG encodes images as one pixel-sized image file, on the other hand, PNG format encodes images as one pixel.

Further, JPEG allows for storing images as multiple files. JPEG files have an .JPEG extension, whereas PNG files have the .PNG extension.

Image format: PNG represents the image as a two-dimensional matrix of colors and can have different color blending and transparency effects. PNG must be uploaded to a web server with a certain name. PNG has no embedded ICC profile that produces bit-for-bit identical images for the whole range of color spectra.

Instead of such a profile PNG supports various bitmaps for the image to be applied with a set of palettes to produce the color at different levels. The available bitmap sets depend on image size. PNG supports image rotation, cropping, zoom, scales image both vertically and horizontally.

PNG has more than two drawing modes. Each of them is represented by a special comma-separated list, where each list has its own set of commands to draw an image.

JPEG and PNG are both a type of image format to store images. PNG is the lossless format to store images whereas JPEG uses a lossy compression algorithm to store images. Generally, JPEG can store image data losslessly with large file size, though, there is a size restriction for PNG format to store image data.

Example: If you are going to add an image of 2.39 MB in PNG file format, it may cause problems when you try to save the file to disk as it is going to load over 64 Kbs.

The most that you can upload with a 2.39 MB file size is 35 Kbs as per the specification and you should increase it if you have high-performance requirements.
