JPEG (Joint Photographic Experts Group) is the world's most widely used image file format for digital photography. Due to its advanced discrete cosine transform (DCT) lossy compression algorithm, JPEGs provide an exceptional balance between visual quality and file size.
While PNG files use lossless compression, JPEG compression is intrinsically lossy. When a photo is saved as a JPEG, frequency information is analyzed and high-frequency color variations that the human eye is less sensitive to are discarded. By choosing an optimal quality level (typically 75% to 85%), you can achieve up to 90% file size reduction without any noticeable difference in visual clarity.
When applying for government online forms or uploading job documents, portal servers often strictly require file sizes under 20KB, 50KB, or 100KB. ReducerImage's Target File Size engine uses a real iterative binary search. It tests multiple quality coefficients on your image and calculates exact output Blob bytes in real-time until the best quality candidate below your designated KB limit is produced.
Unlike traditional online image compression websites that require uploading your private family photos, passport scans, or sensitive documents to third-party cloud servers, ReducerImage executes all compression routines 100% locally inside your browser using the HTML5 Canvas API and Web Workers. Your images never cross the network.
