Compress your images without uploading them anywhere.

Why image optimization matters

Images account for roughly half of a typical web page's weight. Uncompressed photos shipped straight from a camera or design tool can easily exceed 3-5 MB each, stalling page loads on mobile connections and hurting Core Web Vitals scores. Reducing file size by 60-80% through quality adjustment and format conversion is usually possible with no visible difference at screen resolution. WebP generally delivers the best size-to-quality ratio for photographs, while PNG remains the right choice for graphics with transparency or sharp edges.

Most online compressors upload your files to a server. This tool does not. Every pixel stays in your browser tab using the Canvas API, so there is zero network transfer, no file size limits beyond what your device can handle, and no privacy concerns. Pick a format, adjust the quality slider, and download the result — or batch-process an entire folder at once.
