Page weight is mostly images, and most images are bigger than they need to be. The ChrysoKit Image Compressor cuts file sizes without sending your photos through someone else's server.
Why use it
Compression sites are a privacy risk. Family photos, internal screenshots, draft designs: none of them should be uploaded to a stranger's machine. Ours does the work locally.
How to use the Image Compressor
- Drag and drop one or more images onto the page.
- Pick a quality target (or trust the smart default).
- Wait a moment for the compression to finish.
- Download individually or as a zip.
Features worth knowing
JPEG, PNG, WebP
Three of the most common formats, all handled locally.
Batch mode
Drop a whole folder of images and compress them in one go.
Preview before download
Compare original and compressed side by side.
Pro tips
- JPEG quality 80-85 is usually indistinguishable from 100 to the eye, at half the size.
- PNG is best for graphics with sharp edges; JPEG is best for photos. Picking the wrong format is the most common compression mistake.
- WebP can save another 20-30% on top of JPEG with similar quality. Use it when your audience supports it.
Privacy first. The Image Compressor runs entirely in your browser. Nothing you enter is sent to a server.
If you ship images on the web, run them through the Image Compressor first. Faster pages, lower bandwidth, no upload required.
