Bulk Image Compressor – Batch Compress Multiple Photos to ZIP

The Bulk Image Compressor is engineered for photographers, web administrators, and content marketing teams who need to optimize dozens or hundreds of image files simultaneously without repetitive single-file handling. Accepting mixed batches of JPG, PNG, WEBP, and HEIC files, this batch optimization engine leverages multi-threaded browser Web Workers to compress multiple graphics concurrently using client hardware acceleration. You can enforce a universal compression quality percentage, set a maximum bounding pixel width, or convert all files into lightweight WebP format simultaneously. Once processing finishes, the tool bundles the optimized assets into a single organized ZIP archive for one-click downloading. A necessary operational limitation is that batch compressing hundreds of high-resolution 24-megapixel camera files requires sufficient free browser RAM; processing files in batches of 50 to 100 images ensures smooth performance.
