LISTSITE / IMAGE STUDIO V3

Batch Image Compressor

Compress several images in one workflow and collect the results in a ZIP.

Select an image to begin.

Settings

Choose up to 20 images

Maximum long edge (pixels)

JPG quality (20–95)

Processing happens in this browser tab. Keep a copy of your original files.

How to use this tool

Add multiple images, choose the compression settings, start processing and download the ZIP. Check individual outputs before using them.

Before you download

Compression savings depend on the images. Large batches can use considerable browser memory.

Example workflow

Choose a small test batch first and inspect its exports before processing the rest of a collection. Use consistent settings for images with similar purposes. Keep the tab open until the ZIP is ready and verify its contents after extraction.

Check your result

A compressed source can still use substantial memory when decoded. Use fewer files per batch if your phone slows down. Review individual dimensions and formats, since different pictures may reach different sizes at the same settings.
