About Bulk Image Compressor
Bulk Image Compressor shrinks many images at once. Add a batch of JPG, PNG, WebP or AVIF files, choose the output format and how hard to compress, and download them one by one or together in a single ZIP. Each image keeps its original dimensions.
Compression runs in your browser, so a whole folder of photos can be made smaller without any of them being uploaded.
