How much can I reduce an image file?

Typically 50-80% size reduction. A 3 MB JPEG becomes 500-800 KB at quality 80 with virtually no visible difference.

Which image formats are supported?

JPEG, PNG, WebP and GIF. For best results use JPEG for photos and PNG for graphics with transparency.

No. Compression only reduces file size — the image dimensions (width × height) remain unchanged.

75-80% is the industry standard for web images. At this level, most people cannot detect any quality difference.

Batch compression is available with FileSwiftly Pro. The free tool compresses one image at a time.
