What it does
This tool reduces an image's file size to a target, such as 100 KB, without uploading it. It lowers the quality step by step until the file fits. If lowering quality alone is not enough, it also reduces the dimensions. The result is saved as a JPG or WebP file, depending on the page.
About this page

Frequently asked questions
Is my image uploaded anywhere?
No. The compression happens in your browser, and the file never leaves your device.
Why is my result larger than the target?
Some photos cannot reach very small targets even at low quality and smaller dimensions. When that happens, we show a note and give you the smallest file we could make.
Will the image look worse?
Some detail is lost when a file is compressed to a small size. The tool keeps the quality as high as the target allows.
What formats can I compress?
JPG, PNG and WebP images can be loaded. The result is saved as JPG or WebP, which are far smaller than PNG for photos.
