Frequently asked questions
Is this image compressor really free?
Yes. It is completely free with no sign-up, no watermark and no daily limit, because all processing happens on your own device.
Are my images uploaded to a server?
No. The compression runs entirely in your browser using the HTML canvas, so your image never leaves your device and nothing is stored anywhere.
Which format gives the smallest file?
WebP usually produces the smallest file at the same visual quality, followed by JPEG. PNG is lossless, so it compresses least but keeps every pixel exact.
