Download the ZIP
Each photo comes out just under the limit, all together in one ZIP.
Why this size
One limit, every photo
Upload forms, marketplaces and email all cap the file size. The compressor brings each photo just under your limit: it lowers the JPG quality first, in small steps, and only shrinks the pixels when quality alone cannot get there. Faces and text stay as sharp as the limit allows.
Everything happens in your browser, so a folder of photos never leaves your device.

How the tool works
The compressor first lowers the JPG quality at full resolution, testing several settings until the file is just under the target. Only if quality alone cannot get there does it reduce the width and height, a little at a time. The result is a JPG. Everything happens in your browser; your images are never uploaded.
