JPG Compress

How to compress JPG images

1. Drop one or more JPG or JPEG files on the box above, click it to choose files, or paste a screenshot with Ctrl+V.
2. Move the quality slider. Every image is re-compressed as soon as you let go, and the table shows the size before and after.
3. Optionally enter a maximum width. Photos straight from a phone are often 4000 pixels wide; 1600 to 2000 pixels is plenty for a website or email.
4. Click Compare to check the result with a before/after slider, then download single files or everything as a ZIP.

Why smaller JPG files matter

Images are usually the heaviest part of a web page. Lighter images load faster, improve Core Web Vitals such as Largest Contentful Paint, use less mobile data and fit within email and upload limits. Shrinking a 4 MB phone photo to 300 KB is common without any visible change at normal viewing size.

Tips for the best result

• Resize first, then compress. Halving the width cuts the pixel count by three quarters, which saves far more than lowering quality.
• Keep a master copy. JPG is a lossy format, so every save throws away a little detail. Compress from the original, not from an already compressed copy.
• Use PNG or WebP for graphics. Logos, screenshots with text and flat illustrations look cleaner as PNG or WebP than as JPG.

Private and fast by design

This compressor runs entirely in your browser using its built-in image encoder. There is no upload queue, no waiting for a server and no account. Your photos stay on your device, and camera metadata such as GPS location is stripped from the compressed copies.
