Question 1

What image formats can I compress?

Accepted Answer

This tool supports JPEG and PNG image formats for uploading. All images will be converted to JPEG format upon compression.

Question 2

Are my images uploaded to a server?

Accepted Answer

No, all image processing and compression happen directly in your web browser. Your images are not uploaded to any external server, ensuring your privacy and data security.

Question 3

How does the quality slider work?

Accepted Answer

The quality slider ranges from 0.05 (highest compression, lowest quality) to 1.0 (lowest compression, highest quality). A lower value will result in a smaller file size but may reduce image detail.

Question 4

Is there a file size limit for uploads?

Accepted Answer

Since processing is done in your browser, there's no strict server-side limit. However, very large images (e.g., over 20-30MB) might perform slowly.

Question 5

What is the best quality setting to use?

Accepted Answer

For web use, a quality between 0.7 (70%) and 0.85 (85%) often provides a good balance between file size reduction and visual quality.
