About Compress Image
Compress Image reduces the file size of a picture by lowering its quality a little. Smaller images load faster on websites and are easier to send. You control the quality with a simple number from 10 to 100.
How to use Compress Image
- Click “Select image” or drop a JPG or PNG onto the page.
- Set the quality from 10 to 100. A value near 70 is a good start.
- Click “Process image”. The file downloads only if it is smaller than your original.
When is Compress Image useful?

- Send photos by email without hitting the size limit

Frequently asked questions
What quality number should I use?
A value around 70 keeps images looking good while cutting the size noticeably. Lower it for smaller files.
What format is the result?
The compressed image is saved as a JPG file.
What happens to transparent PNG images?
JPG does not support transparency, so transparent areas are filled with white. Keep the original PNG if you need transparency.
Why was nothing downloaded?
The tool downloads the result only when it is smaller than your original. If your file is already well optimised, lower the quality number and try again.
Is Compress Image free to use?
Yes. Compress Image is free, with no sign-up and no usage limits.
Are my files uploaded to your servers?
No. The work is done in your browser on your own device, so nothing you use here is sent to our servers.
