# Batch processing: compress up to 20 images at once

> Upload up to 20 images per batch and compress them all in parallel. Download results one by one or as a single ZIP, with per-file size savings shown.

Fluximage processes multiple images in a single submission. You upload your files, configure your conversion settings once, and all images in the batch are compressed in parallel — there's no need to re-upload or reconfigure between files.

## Limits

* **Max images per batch:** 20
* **Max file size per image:** 20 MB

<Note>
  If you need to process more than 20 images, split them into multiple batches. Each batch runs with its own settings, so you can use different formats or quality levels across batches if needed.
</Note>

## Shared settings

Every image in a batch is processed with the same conversion settings: format, quality, dimension limits, watermark options, and AI features. There is no way to apply different settings to individual images within a single batch.

If you have images that need different output formats or quality levels, process them in separate batches.

## Parallel processing

All images in a batch are compressed at the same time, not sequentially. A batch of 20 images takes roughly the same amount of time as a batch of 1.

## Downloading results

Once processing is complete, you can:

* **Download individual files** — click the download button next to any image in the results table
* **Download as ZIP** — download all optimized images from the batch in a single archive

## Size savings dashboard

The results table shows each image's **original size** and **optimized size** side by side. You can see exactly how much each file shrank before you download anything.
