How to compress an image

1 Add an image; it is compressed immediately at the current quality and the size comparison appears.
2 Move the quality slider to trade size against fidelity; the result recompresses live so you see the effect at once.
3 WebP usually lands 25 to 35 percent smaller than JPG at the same visual quality; pick JPG when the file must open everywhere.
4 Hover the preview and click the eye to inspect the compressed image full-size before downloading.

What quality setting should I use?: 80 is the sweet spot for photos: large savings with no visible difference at normal viewing. Go to 60-70 for email attachments, stay at 90+ when the image will be edited again.
Why did my PNG get so much smaller?: PNG stores photos losslessly and therefore hugely; re-encoding as JPG or WebP applies photographic compression. For graphics with sharp edges and few colors, PNG can actually be the smaller choice.
Does compressing change the image dimensions?: No, width and height stay identical; only the encoding changes. To also shrink dimensions, use the resize tool first, which saves even more.
Is my image uploaded anywhere?: No. Compression runs entirely in your browser; the image never leaves your device.
