About JPG Compression
JPG (JPEG) is the world's most common image format, used for photographs, web banners, and social media posts. Its lossy compression algorithm works by discarding high-frequency detail that the human eye is less sensitive to — the same principle behind MP3 audio compression.
CocoConvert's JPG compressor lets you dial in the exact quality level, from maximum fidelity (95) for print work down to web-optimised (60-80) for faster page loads. At quality 75, most images see a 60-80% file size reduction with no visible difference at normal viewing distances.
Beyond quality adjustment, CocoConvert strips EXIF metadata (camera model, GPS coordinates, timestamps) which often accounts for 10-50 KB per image. For privacy-conscious users, this is a security bonus as well as a size reduction.
Batch compression is available: Pro users can compress up to 100 JPG images in a single batch. Every file is processed on secure servers in Germany and deleted within 24 hours.
