Hi!
It is best if the client publishes the layouts in png format because in this format, the compression doesn’t affect the quality of the image.
Unlike JPGs, which blur images at a certain point, a PNG file will always look at least as sharp as the original image. Unfortunately, PNG files also tend to be a bit larger than JPG files, especially when they’re high resolution.
Thus, JPG compression tends to create smaller file sizes at the cost of image quality. However, PNGs are better for capturing lossless images, and in situations where minimizing file sizes isn’t of utmost importance. Best,
