Compress JPEG

This tool compresses JPEG images by re-encoding them with optimized quality settings. The compression runs entirely in your browser — no file upload to a server.

JPEG is a lossy compression format, meaning some image data is discarded to achieve smaller file sizes. This tool re-encodes at 80% quality, which provides an excellent balance between file size and visual quality.

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.

JPEG compression explained

Lossy compression: JPEG reduces file size by discarding image data that is less noticeable to the human eye. Higher quality means less data discarded.

Quality levels: Quality 80% is typically the sweet spot — visually nearly identical to the original but significantly smaller.

Best for: JPEG is ideal for photographs and complex images with many colors and gradients.

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)
