How to Compress an Image Below 1 MB
A file-size limit is easiest to hit by controlling both dimensions and encoding quality. ImageShrink does both locally, so the original image never leaves your browser.

Start with the right format
Use WebP for most photos and website images. JPG is widely compatible for photos. Keep PNG for screenshots, sharp graphics or transparency; photographic PNG files are often much larger.

Set a sensible maximum width
For online forms and email, 1600–2000 pixels is usually enough. Choose 1920 px first. Smaller dimensions remove more data than repeatedly lowering quality.
- 03
Enter the target
Set Target KB to 1000, choose about 80% quality and compress. The tool gradually lowers quality when necessary. If a detailed image is still too large, try 1600 px or 70–75% quality.

Check before replacing the original
Open the downloaded file and inspect faces, text and fine edges at normal viewing size. Keep the original separately; compression is designed for sharing, not archival storage.
