Compress JPEG

This tool compresses JPEG images by re-encoding them with optimized quality settings. The compression runs entirely in your browser.

JPEG uses lossy compression, meaning some image data is discarded to achieve smaller file sizes. The visual quality remains high while the file size is significantly reduced.

How to use

  1. Drag and drop JPEG files onto the upload area, or click to select files.
  2. Each file is compressed automatically and the compression rate is displayed.
  3. Download individual compressed files or use Download All to get a ZIP archive.

About JPEG compression

JPEG compression works by analyzing the image and removing visual information that is least noticeable to the human eye. This is why it is called lossy compression.

Typical JPEG compression achieves 40-60% file size reduction with minimal visible quality loss. The compression ratio depends on the original image content.

Compress with Python

You can compress JPEG images programmatically using Python with the Pillow library:

from PIL import Image

original = Image.open('input.jpg')
original.save('compressed.jpg', optimize=True, quality=80)
