How it works
- 1
Choose JPEG files
Select or drop one or more .jpg or .jpeg images.
- 2
Compress locally
Your browser re-encodes each photo sequentially at a balanced quality setting.
- 3
Compare and download
Review the original size, optimized size, and percentage saved.
Why use this tool?
No upload
JPEG pixels stay on your device throughout compression.
Useful measurements
Results show the real file-size change instead of an estimate.
Unlimited local use
No account, daily image count, or watermark is required.
Common examples
Website photography
Reduce large camera JPEGs before adding them to a landing page or article.
Email attachments
Make a photo easier to send while keeping its original pixel dimensions.
Upload a source above to see measured original bytes, output bytes, and percentage saved for your own image.
Privacy and limits
Optimization happens in this tab. We do not upload the selected image or send its filename to analytics.
- Repeated JPEG compression can introduce visible artifacts, especially around text and sharp edges.
- Metadata is removed by the default quick preset.
- Very high quality settings may produce a file close to, or larger than, the original.
Frequently asked questions
Are JPEG images uploaded?
No. Compression runs locally in the browser and the image is not sent to our server.
What quality setting should I use?
A setting around 75–85 is a practical starting point for web photos. Inspect the result before replacing an original.
Will this change image dimensions?
The quick JPEG preset keeps the original dimensions. Use the resize tool when you also need fewer pixels.
