Can I print my photos after JPEGmini optimization?Ībsolutely. You are welcome to test the quality on your own photos: After optimizing them with JPEGmini, compare them side by side at 100% zoom (“Actual Size”), where each pixel on the screen corresponds to a pixel in the photo. JPEGmini technology has undergone extensive user testing according to the ITU BT.500 standard, which proved that average users could not distinguish between original photos and JPEGmini photos. How do I make sure that the quality of my photos is not affected by JPEGmini? For further details, see the technology section. JPEGmini works by analyzing the input image using a unique quality detector which imitates the human visual system and based on this analysis applying the maximum amount of compression which will not cause visible artifacts. Although these formats presumably offer better compression than JPEG, JPEGmini’s perceptual recompression technology can produce JPEG files that are smaller in size than corresponding JPEG2000, JPEG-XR or WebP files. Newer formats such as JPEG2000, JPEG-XR and WebP have not gained significant market share yet. JPEGmini uses the standard baseline JPEG format, which is by far the established market leader in the image compression space. How does JPEGmini compare with JPEG2000, JPEG-XR, WebP, or other image formats?

JPEGmini files are optimized JPEG files, whose parameters have been tuned to significantly reduce the file size without affecting perceptual quality.

JPEGmini files are in standard JPEG format, which can be viewed and edited by any browser, photo software or consumer device. If you have an image-intensive website, your pages will load faster, improving user experience, monetization, and SEO, and you’ll also reduce your storage and bandwidth costs. With JPEGmini you can store more photos on your hard drive and online photo service accounts, attach more photos to your emails and upload your photos faster to the web. JPEGmini is a photo optimization technology that reduces the file size of JPEG photos by up to 5X while preserving the resolution and quality of the original photos.
