Compress a batch toward the file-size limit you need.
When a form, email workflow or website has a maximum image size, a generic quality slider can mean repeated trial and error. BatchKit includes a target-size compression mode where you enter the maximum KB you want and process the batch together.
Compress images by target KBHow to use target-size compression
- Add the images you need to reduce.
- Turn on Compress.
- Select Target size instead of Quality.
- Enter the maximum KB you want.
- Process the batch and review the resulting file sizes.
Why the result can vary
Image compression is content-dependent. A detailed photo and a simple graphic may require different quality levels to reach the same file size. Target mode is designed to aim for the requested maximum, but you should still review the final output when a destination enforces a strict limit.
Useful examples
Use it when you need to reduce photos before an email, keep upload files under a portal limit, shrink a folder of website images, or standardize a mixed batch before sharing it.
Target-size compression FAQ
Can I enter a value such as 500 KB?
Yes. Enter the maximum KB value in Target size mode and BatchKit will process each image toward that limit.
Which formats work best?
Target sizing works best with JPG, WebP and AVIF output because their compression quality can be adjusted.
Can I process several images at once?
Yes. The same target-size setting can be applied across the batch.
