So far, when we upload an image on Twitter, the site compresses the image and results in lower image quality. However, Twitter has now announced that it will no longer compress your images uploaded to Twitter through the web.
According to Twitter engineer Nolan O’Brien, the social media giant will now preserve JPEGs as they are encoded for upload on Twitter for web.
Previously, Twitter just transcodes the images for upload, which results in smaller image sizes but reduced image quality.
For example, Nolan also shared a photo, which is actually a guetzli encoded JPEG at 97-percent quality with no chroma subsampling. However, to see the actual impact, click the example image > left-click > open image. The results are pretty awesome.
A guetzli encoded JPEG delivers high-end image quality with a significantly smaller image size at equivalent quality.
Nolen also clarifies crucial information that it will only apply to bitmap encoding, no EXIF (metadata) orientation. On the other hand, there are some limitations, no unbounded file size or resolution. The social network will preserve 8 megapixel photo and even up to 16 megapixels (but in square aspect ratio)
This change in Twitter can actually make a great impact on the photographers, who love to share their works and can use Twitter as a platform.
