Compress Image
Reduce your image's file size with an adjustable quality slider. Everything happens in your browser — files are never uploaded anywhere.
Great for getting photos under an upload limit or speeding up a page full of images. Drag the quality slider and watch the file size update live, so you can balance size against sharpness before downloading.

Frequently asked questions
How much can I shrink an image without losing quality?
Most photos hold up well down to around 70-80% quality. Use the slider and preview to find the smallest size that still looks good for your use case.
What image formats can I compress?
JPG, PNG, and WebP images are supported for compression.
Are my images uploaded to a server to be compressed?
No. Compression happens entirely in your browser using the Canvas API — images never leave your device.
