Optionally cap the width to shrink huge photos, then click Download compressed.

Private, in-browser compression

Your image is compressed using your own device and never uploaded. No watermark, no sign-up, no size limit. Great for shrinking photos before emailing or uploading them elsewhere.

Why did my PNG become a JPG?

Compression uses the JPEG method, which is far smaller for photos. For graphics with transparency or sharp edges, keep quality high or use a smaller max width instead.

Is the original changed?

No. The original file on your device is untouched — you download a new, smaller copy.
