JPEGmini
JPEGmini recompresses images and video to reduce file size while preserving visual quality. The maker says standard JPEG photo sizes can be reduced by up to 80%, depending on resolution. Desktop Pro optimizes JPEG and HEIC images; paid plans also support H.264 and H.265 video compression. Desktop plans include batch processing, while paid Automations plans add watch folders, background processing, and batch presets. Pro + Plugins lists integrations for Adobe Lightroom, Adobe Photoshop, and Capture One. JPEGmini also offers a Photo Server that runs on company servers and a Cloud service for wedding photographers and filmmakers, which sorts uploaded photos and footage by people into galleries. Cloud capacity varies by tier: Free holds one wedding and 5 GB, Pro holds 55 weddings and 100 GB, and Studio holds 275 weddings and 500 GB. The Cloud FAQ says files are stored in AWS US East and encrypted in transit and at rest; uploaded media is not used to train AI models.
