About this tool
Reduce the file size of an image by resizing it and lowering its quality, all on a canvas in your browser — the file is never uploaded. See the before and after size and how much you saved, then download the result.
Frequently asked questions
Are my images uploaded to a server?
No. Compression happens locally using the HTML canvas, so your photos never leave your device.
Which formats are supported?
JPEG, PNG and WebP. PNG output stays PNG; other formats are saved as JPEG.
