Compress images to reduce file size.

Start with Balanced or light compression and compare before/after at full size. PNG logos with flat colors tolerate higher quality settings; photographic JPEGs shrink more at slightly lower quality without obvious blur. Resize oversized dimensions first—compressing a 4000 px wide photo when the form needs 1200 px wastes detail and file size.

Compress JPG for web when Core Web Vitals and bandwidth matter. Reduce JPEG file size for hero images, blog photos, and thumbnails while keeping acceptable quality on desktop and mobile.
Pair compression with resize to display width—serving 4000 px images in 800 px slots wastes bytes.
Use modern formats like WebP when your stack supports them, with JPG fallback elsewhere.
Upload your JPEG, choose a web-friendly quality preset, download, and test on your staging site.
Example: compress a 2.8 MB hero JPG at 80% quality WebP export—often under 500 KB for blog headers.
Upload a JPG, PNG, WebP, or GIF image, choose a compression level and output format, then compress. The tool may resize very large images and tries multiple quality settings (and WebP plus JPEG in Auto mode) to find a smaller file. Processing runs on your device—files are not uploaded or stored.
Compression is lossy for JPEG output. Very small images or transparent PNGs may not shrink much without visible quality loss.

FAQ
Start around 75–85% for photos. Compare visually before publishing.
WebP often yields smaller files at similar quality. Use convert-image when your CDN supports it.
