Frequently asked questions about batch compression
How do I compress several images at once?
Add several images to Compression mode, review the queue and run the process. SWD Image Compressor processes each image while keeping the original dimensions.
Does batch compression change the dimensions?
No. In Compression, compression keeps the width and height of each image. Resizing is a separate function.
Can I mix JPG, PNG, WebP and AVIF in the same batch?
Yes. You can work with multiple compatible formats in the same batch and the tool will evaluate the best result for each image.
Is each image in the batch optimized separately?
Yes. Each file is processed individually, so the results can vary depending on the content and the original format.
Can I review the results before downloading them?
Yes. The batch flow lets you move through the results and review each processed image before downloading the complete set.
Is the final batch download delivered as a ZIP?
When there are several results, SWD Image Compressor groups the download to make the full batch easier to retrieve.
What happens if one image in the batch does not improve?
If a specific image does not achieve a worthwhile improvement, the tool can indicate that instead of presenting it as a useful optimization.
Is batch compression useful for preparing many images for the web?
Yes. It is a practical option for processing product images, editorial content, screenshots or graphic assets before publishing them.
Does the batch keep transparency when needed?
If an image in the batch needs transparency, SWD Image Compressor can preserve it through compatible formats such as PNG, WebP or AVIF; JPEG does not support transparency.
When should I use batches instead of compressing one image?
When you need to prepare several images in a row and want to save time without repeating the same workflow manually file by file.
