We then converted the original PNG images to the following formats. While most of the images uploaded to Cloudinary are JPEG images, there were about 1 Million PNG images that were uploaded in the last few days. We have more than 70,000 developers signed-up to Cloudinary’s service, managing their sites and applications images, so we have quite a nice diversity of actual image files. In order to make the comparison, we used images that were uploaded to the Cloudinary accounts of our customers. Benchmark results – FLIF is the winnerĪs mentioned above, we wanted to compare FLIF with the other image formats. FLIF is the newest format to join this arena. A few modern image formats aim to solve this problem and provide the best algorithm for storing images losslessly in the most efficient way. This affects the storage space required for saving the original images as well as the bandwidth consumed in uploading and downloading these images, negatively impacting the user experience as well as increasing the IT costs involved.įinding a way to save images without compromising on quality while having the smallest possible file, is definitely important for the modern web and mobile world. However, when you save photos using PNG, the generated files are huge, compared to lossy formats such as JPEG.
It is lossless, so the original image is saved as is, it has a wide color space (in contrast to the 256 colors of GIFs) and it has an alpha channel for supporting the different opacity levels of pixels in images. The PNG format is usually used in such cases. In addition, the most popular lossy format for photos is the JPEG format, which has no alpha channel support and therefore doesn’t support semi or fully transparent pixels, which are required by common graphic design practices (see PNG optimization – saving bandwidth on transparent PNGs with dynamic underlay). A lossless format allows you to keep the original images intact in your backend and decide later on regarding which lossy compression to use when delivering images and thumbnails to your users. However, JPEG is a lossy format, which means that there is a trade off between the file size and the loss of visual quality. JPEG is the most popular format for uploading and downloading images efficiently. Why do you need an efficient lossless image format? The benchmark results are detailed below. We performed a benchmark test and compared the generated FLIF file size with the other lossless image formats.
In addition, we wanted to verify FLIF performance using real life examples of our customers’ user images. Therefore, we quickly added support for FLIF: uploading of FLIF files and dynamic conversion of any image format to FLIF or from FLIF. According to the creators of FLIF, it is supposed to significantly outperform the other image formats that have lossless modes, such as PNG, WebP and the new BPG format.Īt Cloudinary, we always seek to seamlessly leverage the best optimized image formats for any of the different use cases for web and mobile applications.

It is called FLIF, which is an acronym for Free Lossless Image Format. A fresh new lossless image format has recently been introduced.
