100% client-side. Your image never leaves your device.
Choose an image to compress
JPEG, PNG, or WebP · up to 15 MB
PNG and WebP files are converted to JPEG. Transparent areas become white. Target KB uses decimal units (1 KB = 1,000 bytes). Compression may reduce image quality or dimensions; some images cannot reach every target size.

How this image compressor works
Your image is decoded and compressed on this device. The tool adjusts JPEG quality and, when needed, image dimensions until the downloaded file is at or below the selected byte limit. The displayed file size is checked before success is shown.
Compression uses JPEG, which is lossy and does not preserve transparency. Transparent pixels are filled with white. Animated WebP files become a single still image. Very small targets or complex images may not be achievable; choose a larger target and retry.
