Bulk Image Compressor
When a site has hundreds of product or blog images, optimizing them one by one is not realistic. Drop a batch, a folder or a ZIP, apply the same settings to all of them and download a single ZIP with the original folder structure — with a report of how much space you saved.

Frequently asked questions
Is there a limit?
Free converts up to 10 images per batch. Pro raises it to 1000 per batch; your device memory is the practical limit for very large files.
What if one image fails?
The rest continue. Failed files are listed with the reason.
Are my images uploaded anywhere?
No. The files are read and processed by your browser on your device. They are never sent to our servers or to any third party.
