Batch Image Compressor

Drag and drop multiple images, check their compressed sizes, and download individually or as a ZIP. All image processing happens locally in your browser. HEIC/HEIF decoding requires an internet connection to load the decoder library.

Note: Animated GIFs use the first frame only. Transparent images are filled with white when exported as JPG. PNG is lossless and may produce larger files. ZIP uses STORE mode to avoid recompressing images. HEIC/HEIF files are decoded locally using heic2any (loaded from CDN on first use); only the first image is processed.
