(Technically, this kind of detail is high frequency image content.) Areas of solid color have essentially no high frequency content so they compress very well without adding compression artifacts but ones with lots of color variations (even ones not very noticeable to the eye) have lots of high frequency content so they do not.Ī very common source of high frequency content in digital photographs is noise, which adds nothing to the sharpness or quality of the photo, but can easily go unnoticed unless the photo is examined carefully at high magnification levels. What this means is not only do the pixel dimensions determine how much compression can be applied without noticeable artifacts appearing in the export, so does how much pixel-to-pixel detail there is in each image you export to the JPEG file format. The tool will remove optional metadata from the source image, such as profiles or comments. Simply upload your images and let us work our magic. Easy to Use Default options do a great job of compressing. You can target a specific file size, a quality level, or even apply lossless compression. A lower quality will thus also reduce the file size. Best Quality Compress JPEG files without sacrificing quality. The better the quality, the higher the file size. XnConvert can also help with stripping and editing metadata, cropping and resizing, brightness and contrast, customizing color depth, blurring and sharpening, masks and watermarks, and other transforms. Start Add example file Best Quality No visual difference Smallest File Tiny file size Best compression Quality: Decide which quality the resulting image should have. ![]() (There is a non-lossy form of JPEG compression but it is rarely used & Affinity does not support it.) XnConvert is a utility that you can install on the desktop to convert different image formats, including WebP. ![]() So it is widely used in web publishing to reduce the image size maintaining the image quality. With the compression technique it can reduce the image size without losing the image quality. Also keep in mind that JPEG compression is lossy, meaning even at 100% "quality" some details will be lost. JPG JPG, also known as JPEG, is a file format that can contain image with 10:1 to 20:1 lossy image compression technique. ![]()
