About Batch Image Compression
Compress dozens of images simultaneously without uploading a single file to a server. Drag and drop an entire folder or select multiple files; the tool processes each image in parallel using Web Workers for fast, non-blocking compression. Individual quality settings can be applied per-format (JPEG, PNG, WebP). A before/after size summary is displayed for each file, and a ZIP archive of all compressed images can be downloaded with one click. Ideal for photographers preparing image galleries, developers optimising web assets, or anyone with a large collection of images to shrink. All processing is client-side and completely private.
Frequently Asked Questions

Can I download all results as a ZIP?
Yes. After compression, a single "Download All as ZIP" button packages every output file.
Can I use different quality settings per file?
The tool applies a global quality setting; per-file overrides are shown in the results list.
