How Image Compression Works (and How to Get the Best Result)
What compression actually does
Compression makes an image file smaller by storing the same picture more efficiently. JPG and WEBP use lossy compression: they discard fine detail that the human eye is unlikely to notice, and the quality slider controls how aggressively they do it. PNG is lossless, so it keeps every pixel exactly and the slider has little effect on it. For big savings on photographs, JPG or WEBP is almost always the better choice.
Choosing a quality setting
There is no single correct number. The right setting depends on where the image will be used. As a starting point:
- 95% for photography and anything you may print or edit again
- 80% for websites and blog posts, which is the sweet spot for most photos
- 60% for social media, where the platform recompresses your upload anyway
- 30% for email attachments where small size matters more than detail
Why smaller images matter
Images are usually the heaviest part of a web page. Oversized files slow down loading, use up visitors' mobile data, and are one of the most common reasons a page scores badly on speed tests. Page speed is also a factor in how search engines rank a page, so compressing images before you upload them is one of the easiest improvements you can make.
Private by design
Compression runs entirely inside your browser using the Canvas API and a compression library. Files up to 20 MB each are supported, you can add several at once, and nothing is ever uploaded to a server. That also means it works fast, because there is no waiting for an upload to finish.
