How to Compress Images Without Losing Quality

Heavy images slow page loads and bounce rates. Compression reduces bytes while keeping photos acceptable for blogs, stores, and support tickets.

Resize before you compress

A 4000px-wide photo displayed at 800px wastes bandwidth. Resize images to the display size first — see resize images for your website.

Pick the right format

Photos: JPG or WebP. Graphics with transparency: PNG. Use Convert Format when the source type is wrong.

Compress with a quality preset

Compress Image with a High or Balanced preset first. Compare preview size before download — aggressive settings show on gradients and faces.

Build PDFs from optimized images

Emailing scans? Compress photos, then Image to PDF or JPG to PDF, and optionally Compress PDF.
