How does facebook resize images




















I have come across a handful of photographers who feel as though uploading to Facebook as a PNG file instead of a JPEG file gives their images the best display quality. While I can understand where they are coming from, the fact of the matter is that if you upload a JPEG to Facebook with the correct dimensions especially larger, at the human eye cannot distinguish the difference between a JPEG and a PNG.

If you feel as though uploading as PNG makes a difference on Facebook, then by all means, go for it. If you are on the fence, though, stick with JPEG - it is a smaller file extension, so it takes up less room on your computer, and in the context of Facebook's image window, it will not make any difference whether it is JPEG or PNG - all that matters is that you upload at the correct dimensions for Facebook.

As a general rule of thumb, JPEGs are generally used for photo files, while PNG is typically used for graphic design files, such as logos. PNG files use less compression than JPEG, and tend to handle solid colors better, making them very useful in graphic design.

For example, the following have different sizes for your profile photo, a shared image, and a cover or banner image:. The numbers you see above like and refer to the proportions of the image or the ratio of its width to its height.

Most cameras shoot with an aspect ratio of So that means that to share your image on social media you may need to crop it.
