How to Compress an Image (Free & Private)

Big image files are slow to upload and can be too large to attach. Compression shrinks them while keeping them looking good.

Compress an image

1. Open Compress Image.
2. Drop in your photo and pick a quality level.
3. Download the smaller version.

Everything runs in your browser — nothing is uploaded.

• Resize first. A 4000px photo displayed at 800px is wasting space — use Resize Image.
• Switch to WebP. It's smaller than JPG at the same quality — try Convert Image.
• Choose a medium quality setting; the difference is usually invisible.
