Drag and drop a folder or select multiple files. Our bulk compressor handles up to 50 images in a single batch — JPEG, PNG, WebP, AVIF, and HEIC all supported.
✓ Use WebP for smallest output
Selecting WebP as output format typically reduces file sizes 30–50% compared to JPEG at the same visual quality. All modern browsers support WebP.

After compressing, click "ZIP All" to download every compressed image in a single ZIP file. Windows 11 and macOS can open ZIP files without any extra software.
