Compress Image reduces a photo's file size with a quality slider, and can convert it to WebP for even bigger savings. It's ideal for speeding up a website or fitting under an upload limit. The before-and-after sizes are shown so you can dial in the right balance.
Drop a JPG, PNG or WebP file in; its current size is displayed.
Slide to your preferred quality, and optionally tick Convert to WebP for a smaller file.
Export to compress, then see exactly how much smaller the image became.
Often 50–80% for photos, depending on the quality you choose and whether you convert to WebP.
JPEG and WebP use lossy compression, so lower settings trade some detail for size — the slider lets you find the sweet spot.
For photos, yes — WebP is much smaller than PNG at similar quality while keeping transparency.
