100% Private – Images never leave your device

Bulk Image Compressor

For bloggers and store owners who need to shrink a whole batch of web images at once, without sending sensitive product or unpublished photos to a cloud server. Everything runs on your device, so a 20-image batch is processed locally and downloaded as individual files or one ZIP.

Drag and drop images here, or click to choose files

Up to 20 images per batch. For dozens of images, run another batch of 20.

PNG output ignores quality. WebP and JPEG use it.

How to use this tool

  1. Drag and drop up to 20 images, or click to choose them.
  2. Pick WebP, JPEG, PNG, or keep the original format, set quality and max width.
  3. Press Compress all, check the before and after sizes, then download one by one or all as a ZIP.

Why this page is separate

Each tool on this site has its own page, its own title, and its own explanation, so search engines can match a specific search — for example, this exact job — to this exact page, instead of to one generic homepage. That is also why the steps and questions above are written for this tool only, not copied from the other tools.

Do my images leave my device?

No. This page uses only your browser's Canvas code and a ZIP builder in the same page. There is no upload endpoint and no external library.

What quality should I use?

80% is a good default for web photos. Lower it for thumbnails, raise it for hero images where detail matters.

Why only 20 per batch?

To keep phones and low-memory laptops stable. Run another batch of 20 for dozens of images.
