Image Compressor
Shrink JPG, PNG and WebP file sizes with a quality slider — see the size before and after, instantly.
How to use it
Choose an image, pick a format and quality, and press Compress. For most photos, 75–85% quality cuts the file size by half or more with no difference your eye can see. WebP usually beats JPG by another 20–30% at the same quality and is supported by all modern browsers.
Why file size matters
Large images slow websites down, eat mobile data, and bounce off email attachment limits. Compressing product photos, blog images and listing pictures before you upload them is the single easiest speed win — and it costs nothing here.
Frequently Asked Questions
Are my images uploaded anywhere?
No. Compression happens on your device using the browser's built-in canvas. Nothing is sent to a server.
Why does PNG not get smaller with the quality slider?
PNG is lossless, so the quality setting does not apply. Convert to JPG or WebP for big savings on photos.
