Why compress images?
Large images slow down websites, bloat emails, and eat storage. Image compression reduces file size while keeping visual quality — the classic trade-off controlled by a quality slider.
This compressor runs entirely in your browser using canvas re-encoding. Your images never leave your device, which makes it safe for photos of documents, products, or anything sensitive.
Compression tips
For web use, quality 60-75% is usually indistinguishable from original to the eye but cuts size dramatically. For print, stay above 85%. This tool shows the before/after size so you can tune the slider until the file is small enough.
