Compress and reduce image file size without visible quality loss. No upload required.
Large image files are one of the biggest causes of slow websites. Google uses page speed as a direct ranking factor, and images are typically the heaviest assets on any web page. Compressing images before uploading can reduce load times by 40–80% with no visible quality difference. This tool processes images entirely in your browser using the Canvas API — your files never leave your device.
Most photographs can be compressed to 65–80% quality with no perceptible quality loss to the naked eye. At 75% quality, a 2MB photo typically compresses to 300–500KB — a 75–85% reduction. For website images, this dramatically improves Core Web Vitals scores, which directly affect search rankings. The preview lets you compare before downloading.
