Compress Many Images at Once
Upload a batch of images and compress them all to a smaller file size in one go, then download the whole set as a ZIP. Lower the quality slider to shrink files further; WEBP usually gives the smallest result.
Features
- Compress dozens of images in one batch
- Adjustable quality for size vs. clarity
- Export as JPG or WEBP
- Download everything as a single ZIP
JPG vs. WEBP
WEBP typically produces 25â35% smaller files than JPG at the same visual quality, and it's supported by all modern browsers. Use JPG only when you need maximum compatibility.
Why compress in bulk
Large images slow down pages and eat storage. Compressing a whole folder at once â instead of one image at a time â saves hours when preparing galleries, product catalogs, or email assets.
Private & Processed Locally
Every image is compressed in your browser and zipped locally. Nothing is uploaded to a server.
