Compressing a folder one image at a time wastes clicks. Bulk Image Compressor applies one quality or target-size setting to as many as 50 images in a single run, while preserving each image's natural dimensions and choosing a sensible output format for its source. The work happens locally in your browser, so the batch never needs to be uploaded to a server.
How it works
1. Choose up to 50 images
Select several JPG, PNG, WebP, AVIF, HEIC, HEIF, or GIF files together, or drag the selection onto the tool. Mixed formats can be processed in the same batch, and the files stay on your device throughout.
2. Use one setting for the batch
The default quality aims for a useful reduction without making ordinary photos look noticeably worse. Open Adjust to choose a different quality or a target size; that setting is then applied independently to every image in the batch.
3. Download one ZIP
After processing, the tool shows a thumbnail for every result and combines the files into one ZIP download. Unzip it on your device to get all of the compressed images with distinct, familiar filenames.
