Need to shrink a batch of photos before sending them or saving them to an archive? Caesium compresses image files, with controls for reducing resolution and a live preview to check the visual result as you adjust settings.
Add images and adjust compression
Load several pictures into Caesium and process them together instead of handling each file separately. Adjust compression settings and use the real-time preview to see how those choices affect the image. The preview gives you a way to balance a smaller output file against visible detail before saving the results.
Caesium supports JPG, PNG, WebP, and TIFF images. Resolution can also be reduced when a smaller image is appropriate, alongside compression of the file itself.
Preserve details that matter
Compression changes file size, and the preview helps you judge its effect on image quality. Caesium also provides metadata storage options, so you can choose how image metadata is handled during processing.
- Use the preview while tuning settings for individual images or a batch.
- Choose whether to retain metadata through the available storage options.
Keep batch output organized
Folder-structure support gives you an option for keeping output arranged around the source folders when processing a collection.
