Compress images in your browser

How do you compress an image without losing quality?

A JPG or a WebP is made smaller by removing detail the eye is least likely to notice, so some loss is always involved. In practice a quality setting between 75 and 85 removes most of the file size and very little of what you can see. Compare the two files at the size the image will really appear on screen, not zoomed in. A PNG works differently: it is lossless, so the only way to shrink it much is to save it as JPG or WebP instead.

Why do image file sizes matter for an online store?

Every image on a product page has to download before the page settles, and a slow page loses shoppers. Heavy photos are the most common reason a store feels slow, because a phone camera writes files far bigger than a web page needs. Compressing them is the cheapest speed fix there is. Nothing about the page changes except the number of bytes.

Should I save as JPG or WebP?

WebP files are usually smaller than JPG at the same visible quality, and every current browser can display them. JPG is the safer choice when an upload form lists the formats it accepts and WebP is not one of them. A photograph should not be a PNG unless it needs a transparent background, because PNG stores photos very inefficiently.

What if the photo itself needs work?

Compression changes the file, not the picture. A smaller file will not help if the background is messy, the light is flat or the product is sitting on a kitchen table. The DesignerBox studios rebuild the shot from the same photo: a clean cut-out, a studio background, an image on a model, or a product video.
