Compress images
Shrink your photos for a website, an email or an online form. Set the quality and maximum size, compare the weight before and after, then download. Your images never leave your device.
Your files stay on your device — nothing is uploaded.
How to
- Add one or more images.
- Adjust the quality, output format and, if needed, the maximum width.
- Click “Compress” and download your lighter images.
Frequently asked questions
Which quality should I pick?
Between 70 and 80%, the difference is usually invisible while the file size often drops by half or more.
How do I drastically shrink a PNG?
Choose WebP as the output format: it keeps transparency and is far lighter than PNG.
Does resizing help?
A lot. Smartphone photos are often over 4000 pixels wide: capping them at 1920 pixels cuts their size dramatically.
How do I reduce a photo to under 1 MB or 200 KB?
Pick the maximum file size: the tool adjusts quality automatically, then the image dimensions if needed, to get below the limit.
Are my images uploaded to a server?
No, compression is done by your browser. No image is ever uploaded.
