WebP vs AVIF vs JPG for Product Images, With File Sizes From One Photo
We delivered one 205 KB product photo through the Filestack CDN at three widths, three crops and three formats, then measured all 27 files.
Image optimization makes image files smaller and sized to the place they appear, through resizing, format choice and compression, so pages load faster at the same visible quality. These guides compare formats and settings using file sizes measured on real product photos.
