Compress Image
Reduce image file size and compare the result before downloading in the original format.
Up to 50 MB and 40 million pixels. Your original file is unchanged.

Lower: better quality. Higher: smaller target size and more detail loss. Actual savings depend on the image.
How compression works
The expected size is measured from an encoded result at your chosen setting. JPEG, WebP and HEIC use adjustable quality; PNG and GIF reduce the number of colors. Dimensions stay the same. Compression can lose detail, including at low settings, and metadata is removed.
Animated images export their first frame as a still image when re-encoded. If the result is larger than the original, the original file is kept instead. Some images are already well compressed, so moving the slider may not always reduce their size.
