About this tool
Photos from modern phones are often several megabytes — far more than a web page or email needs. Compression trims that weight by removing detail the eye barely notices.
For JPG and WebP we tune the compression quality; for PNG we reduce the color palette, which usually saves 50–80% while keeping transparency intact. Turn on “Reduce dimensions” to save even more.
All compression happens in your browser. Your image is never sent to a server, so it's a safe choice even for personal documents.
Frequently asked questions
Will compressing reduce image quality?
With “Recommended” the difference is practically invisible. If you need maximum fidelity, choose “Light”; if file size matters most, choose “Strong”.
Are my images uploaded to the internet?
No. The image is processed on your own device, inside your browser. We never upload or store it.
Which format is smallest?
WebP usually produces smaller files than JPG at the same quality, and every modern browser supports it. You can pick it under “Output format”.
Why doesn't the file get smaller sometimes?
If the image was already well optimized, compressing it again doesn't help. We'll tell you and give you the original file so you don't lose quality.
