Compress and resize photos in your browser, convert to JPEG, WebP or PNG and compare before and after. Your images are never uploaded.
No. Compression uses your browser's canvas, so photos never leave your device — safe for personal documents.
WebP is usually 25–35% smaller than JPEG at similar quality. Use PNG only for graphics that need transparency or sharp edges.
Lower the quality slider and reduce the maximum width until the 'after' size is below the limit — the new size updates instantly.
