Question 1

Does this tool upload my images to a server?

Accepted Answer

No. All image compression happens entirely within your web browser using HTML5 Canvas APIs. Your original images never leave your device, ensuring complete privacy and security.

Question 2

Why did my PNG image change format?

Accepted Answer

PNG is a 'lossless' format, which means standard compression does not reduce its file size effectively. To achieve significant file size reduction for the web, our tool automatically converts heavy PNG files into modern, highly compressed WebP formats.

Question 3

Does compression reduce image quality?

Accepted Answer

Yes, this is 'lossy' compression, meaning it works by permanently removing some data from the image. However, by adjusting the quality slider (e.g., 70-80%), you can drastically reduce file size while keeping the visual difference virtually undetectable to the human eye.

Question 4

What is the maximum file size supported?

Accepted Answer

Because this tool runs in your browser, the maximum size is technically limited only by your computer's available memory. However, for the best performance without freezing your browser, we recommend keeping individual images under 50MB.
