Compress many images at once
Add a folder-sized group of JPG, PNG, WebP, or BMP images and export compressed WebP or JPG files with one shared quality setting. Files are processed sequentially to keep browser memory under control.
Built-in safety limits
Each batch supports 50 images, 20 MB per image, and 100 MB in total. Files are processed sequentially to reduce the risk of browser slowdowns on phones and lower-memory computers.
Batch compression FAQ
Are the images or ZIP uploaded?
No. Compression and ZIP creation both happen locally in your browser.
Why is the ZIP not much smaller than the output images?
JPG and WebP are already compressed formats. The ZIP is mainly used to package all results into one convenient download.
