Batch Image Prep
Drop multiple images and tune compression before export.
Accepted: PNG, JPG, JPEG, WEBP. Each file is compressed toward the same target in your browser. Downloads appear one by one below, and this workflow does not create a ZIP archive. Large images may fail on phones or low-memory devices.
- Adjust target size for the whole batch.
- Process multiple files in one run.
- Review results and download outputs.

How to use
Batch Image Prep compresses multiple images toward a shared file size target in a single pass. Upload a set of images, set the target size, and download compressed versions for all of them.
- Add your images
Select multiple JPG, PNG, or WEBP files. You can add a full folder of images at once.
- Set the target size
Choose a shared compression target — 100 KB, 200 KB, 500 KB, or 1 MB. The same target applies to all images in the batch.
- Run the batch
Click Compress All. The browser processes each image individually and shows progress for the entire batch.
- Download
Download each compressed image individually, or use the Download All button to get a ZIP of the entire batch.
Tip: For batches with mixed content (photos and graphics), the quality of each output will differ since the tool optimizes each file independently toward the same size target.
