Need to prepare a whole set of photos for a form or a website? The bulk image compressor lets you compress multiple images at once to an exact KB size and download them together in a single ZIP folder. It is built for the times one image is never enough — a family's exam applications, a batch of product photos, or a folder of scans that all need to fit the same limit.

Like the rest of imageto10kb, batch compression runs entirely in your browser. Your images are never uploaded to a server, there is no sign-up, and there is no watermark — just drop them in, set the size, and download the ZIP.

How to compress multiple images at once

  1. Add your images. Drop several photos onto the box, or click to select multiple files at once. JPG, PNG and WebP all work.
  2. Set the target size. Enter the KB size you need — the same target is applied to every image — or tap a preset. Lock exact pixel dimensions if a form requires them.
  3. Compress all. Click Compress all. imageto10kb resizes every image in your browser, showing the new size for each one.
  4. Download the ZIP. Click Download all to save every compressed image together in a single ZIP folder, ready to upload.

Frequently asked questions

How do I compress multiple images at once?

Drop all your images onto the bulk compressor, set one target KB size, click Compress all, and then Download all to get them together in a ZIP folder. Everything runs in your browser.

Is there a limit on how many images?

There is no fixed limit. The tool processes as many as your device's memory allows, which is comfortably dozens of typical photos. Very large batches simply take a little longer.

Are my images uploaded to a server?

No. Every image is compressed locally in your browser using the Canvas API, so your photos never leave your device — even in bulk.

Can I set a different size for each image?

The batch applies one target size to every image, which is what forms usually need. To use a different size, compress that image separately or run the batch again with a new target.

What formats can I use?

You can add JPG, PNG and WebP images, and choose JPG or WebP as the output. The download is a standard ZIP folder containing your compressed files.
