About Bulk Image Compressor
The Bulk Image Compressor compresses many images in one pass and hands them back as a single ZIP. Add a whole folder of photos, set one quality level or size target, and the tool processes each file in the browser and packages the results with JSZip. It is built for clearing out a camera roll or preparing a batch of product shots without uploading anything.

Download the ZIP
Run the batch and download all compressed images together in one ZIP file.
Frequently Asked Questions
How many images can I compress at once?
There is no fixed cap — the practical limit is your device's memory. Desktop browsers comfortably handle hundreds of typical photos in a batch.
Can each image have a different setting?
Bulk mode applies one setting to the whole batch for speed. For per-image control, use the Universal Image Compressor on each file.
What do I get back?
A single ZIP archive containing every compressed image, built in your browser so nothing is uploaded.
Will the originals be changed?
No. The originals on your device stay exactly as they were; you only download new compressed copies.
