![]() Platforms: JPEG mini is compatible with both Mac and Windows operating systems.Plugins for image manipulation tools: JPEGmini Pro Suite is a package that includes the desktop version of JPEGmini Pro with additional plugins for Adobe© Lightroom, Capture One© and Adobe© Photoshop.JPEG mini provides a range of predefined image sizes, as well as the ability to define specific dimensions. Resizing Configurations: JPEG mini includes resizing configurations that allow users to resize batches of images and videos all at once.With its wide popularity, JPEGmini implemented the support into its software, allowing the batch processing of. JPEG mini launched a free website in 2017 that allowed the conversion of HEIC images to JPEGs, ( ). HEIC (High Efficiency Image Format) is an image format that was adopted by iPhones but not all devices, browsers, and applications support it. JPEG mini video supports high bitrate videos, H.264/AVC video tracks, AAC audio tracks in MP4, M4V or MOV containers, with files up to 800 Mbps. JPEG mini can reduce videos by up to 50% while maintaining original quality and playability. Video optimization: The release of JPEG mini 3.3 brought the additional feature of video optimization.JPEG mini optimizes high-res photos, with a resolution of up to 120MP. Image optimization: JPEG mini can significantly reduce the file size of JPEG images by up to 80% without compromising image quality.With the use of this technique, JPEGmini Pro may reduce JPEG picture quality by up to 80%, or 5 times, while minimizing visual imperfections in digital photos. This engine does the image transformation and generates an output that complies with all standards when paired with encode and decode blocks. JPEGmini technology is built around a perceptually aligned image quality measure, which reliably determines the maximum amount of compression which can be applied to each individual image or video frame without introducing visible artifacts. ![]() This technology is integrated into JPEGmini Pro allowing users to reduce the file size of their photos and videos with limited quality reduction. Its technology is backed by 53 internationally granted patents and was awarded a Technology and Engineering Emmy in 2021. Beamr’s clients include companies like Netflix, Viacom CBS, and Snapfish. ![]() The Photo Optimization program was developed by Beamr and was released in 2012.īeamr was founded by Sharon Carmel, an entrepreneur with a background in image and video processing. The tool uses a predefined threshold and determines how far it can compress.Ĭhime back in with your final results/preference.JPEGmini is a desktop application for Mac and Windows designed to reduce the file size of images and videos with limited quality reduction. From experience, the feature I think is unique is the automatic one click processing. Notice how it doesn't compare itself to other software, it just promotes itself. Most hate it because it tries too hard to sell itself when other free open source tools also exist and do the same. I also read on a few other forums users' opinions of jpegmini. Extremely handy! I only wish it showed more of the tool's internal options. I used to have a script for compressing PNGs with PNGOUT but now RIOT allows to process them in batch. I tried the tool the user posted on this thread but it produced some weird results, on a few images it cropped the picture by a few pixels. Messing with the Chroma and Luma channels is something nearly every jpeg compressing tool does and I'd like to know which one I'm using to compare their features. I liked RIOT very much but I wish it showed which external tools it uses besides the PNG ones. Hopefully being open source means others will step up with with cool new ideas. I'm sure there are a ton of optimizations to be made, but to be totally honest my math and C programming skills are not the best. if it's a picture of clouds then lower the quality slightly and if it's an intricate building then increase the quality a bit. One thing I would like to add is some measure of overall image complexity, e.g. what's the average pixel value, how do the pixels vary, what's the relationship between the original variance and the reference block variance, etc. The algorithm I use is SSIM, which works by measuring relationships between pixels in 8x8 blocks, e.g. I haven't read the patents (and won't due to possibly tainting my own code with information from them). JPEGmini actually uses some custom patented algorithm for perceived image quality. That's much better than throwing away too much. ![]() Luckily it errs on the side of caution and throws away less data than JPEGmini. I think the groups of solid colors are problematic. Thanks! Feel free to contribute the bat file if you think it'll be useful for others.
