Question 1

Are my images uploaded to a server?

Accepted Answer

No. Compression happens entirely in your browser using the Canvas API. Your images never leave your device.

Question 2

Which formats are supported?

Accepted Answer

Common web image formats: JPEG, PNG, and WebP. You can also convert between them on export.

Question 3

How much smaller will my image get?

Accepted Answer

It depends on the image and quality setting. Photos often shrink by 50-80% with little visible loss; the tool shows the exact reduction.

Question 4

Will compressing reduce quality?

Accepted Answer

Lossy formats (JPEG/WebP) trade some quality for size. Lower the quality slider for smaller files, or keep it high for near-original quality.

Question 5

Is there a file size limit?

Accepted Answer

Processing is limited only by your device's memory, since everything runs locally.
