Compress JPG Online — Free JPEG Optimizer
Reduce JPG file sizes by up to 80%. Adjustable quality slider for the perfect size/quality balance. Free and private.
JPG is the most common photo format, but camera files are often much larger than necessary. Use the quality slider to find the perfect balance — most photos look identical at 75% quality but are 50-80% smaller. Ideal for web, email, and social media.

How It Works
This compressor uses your browser's native Canvas API and intelligent quality reduction algorithms to minimize image file size while preserving visual quality. Drop your images, adjust the quality slider, and see the compressed result with a side-by-side comparison.
The tool re-encodes images at your chosen quality level, stripping unnecessary metadata (EXIF, ICC profiles) and optimizing the encoding. You see the exact file size savings and visual difference before downloading.
