Bulk Image Compressor
Processing product photos, a scanned document set, or a family's worth of application photos one by one wastes an afternoon. Select multiple files below, set one KB target, and download each compressed copy from the list. Because everything runs locally, even a big batch costs you no upload time at all.
100% private — this tool runs in your browser. Your image is never uploaded to any server.

Frequently asked questions
Is there a limit on how many images I can compress?
No hard limit — processing happens on your own device, so capacity depends on your phone or computer's memory. Batches of 50–100 typical photos work smoothly on an average laptop.
Can I download all results as a single ZIP?
Currently each file gets its own download link, which keeps the tool dependency-free and fast. A one-click ZIP download is on the roadmap.
Do all images get the same target?
Yes — one KB target applies to the batch. If different images need different limits, run them in separate batches or use the single-image pages.
